Baking Perfect Texture Maps Using a Cage | Blender 2.8

[@321357w]

It's good when you make mistakes and correct them live as we can also learn how to correct them following your examples.

[@grabbitt]

Yes I feel that's important too :)

[@pablolopez6721]

very well pointing it out

[@MsPortia12]

Seriously, these videos are super well done are so helpful. I don't mind small errors or changes and editing the video is not worth it. Especially if you preview the video and take notes. It's not like 9:20 is a huge investment in time.

[@TerryMartinART]

I say that exact same thing when I make videos lol... But the partial truth is I don't have patience to edit videos.

[@durgam_sumerian7815]

I was struggling with baking with the previous tutorials but with the Cage method, I got amazing results, and of course, it's all thankfulness for your efforts.

[@foxyfujitora3868]

I know this was an old video. but I just checked it tonight and I really want to thank you, you dont know what this means to me, I've been trying to bake into normal maps for 3 weeks but never got good result till I finally learned from this video, thank you, wish you succeed more and more in this field

[@MikeG-en1zu]

Thank you for this. I have always had difficulty getting truly good normal maps made; now I not only know the reason why, I have a ready solution. This is going to greatly improve my render times, and the overall quality of my art. Along with many of the other tutorial makers here on KZbin (CG Geek, Andrew Price, etc), your content has helped me grow; please keep up the amazing work!

[@ferretscraze11]

I am really glad you had the same ray distance issue I had when baking because last video I was panicking but you solved it here. What a relief!

[@1lllllllll1]

Side tip for finding overlaps: use object viewport coloring, that way the overlap area will stick out visibly.

[@elliejohnson2786]

Honestly, I like that you show mistakes. Following tutorials sometimes gives a false impression of confidence that quickly fades when you try your own projects.

[@G4ADStudios]

Dude, I spent like two hours jumping from video to video looking to fix that exact issue, you've saved my psychological stability

[@fredboussada8025]

Baking with a cage in Blender is something I wanted to learn, especially to get rid of baking in Marmoset (at least for now), thank you very much for the ever helpful tutorials!

[@Skeindem]

This was super useful! As I haven't used baking much before, your baking series were super useful especially this one. Used it on one of the most complicated freelance projects I've ever had :D

[@racheleprojects]

This video was so helpful Grant! Never quite understood how to use the Cage properly. This was very well explained. Thank you!

[@Duticyaa]

Fuck me dude this is amazing. This is basically deciding the ray distance for individual parts. Absolute legend for making this video.

[@gaboxtrox531]

I didn't understand nothing because my english is very bad, but it worked, and I don't know why, thank you for doing this tutorial :D

[@petramala3916]

extremely useful. I have those *valleyball seams or football ball seams* and I hope this wil help me get rid of it. I read a lot of edvices online and none mentioned baking with a cage. BTW, it finally worked very nicely :)

[@derfmode]

I drop render samples from 128 down to 10. Then in “performance” (just below that) I change “tiles” from 64 up to 512. Now it bakes WAY faster and result looks incredible

[@virginijasileikiene1989]

[@Kholaslittlespot1]

Some days it feels like I'm really grasping Blender. Other days I feel like I have only scratched the surface! Wonder if I'll ever get good? Thanks again for your free resources. I'm a mature, self taught student who is not working, so they are very helpful.

[@grabbitt]

Thanks :) keep going and keep having fun :)

[@bluethumbbuttoneek9465]

Howd this tut go for u then

[@ProgNoizesB]

your only scratching the surface if you keep looking on youtube. All the same easy kinda tutorials. But if you ask more difficult stuff, they can't do shit. The uploader don't even show the end result which i have on my screen right now. It's horrible. He probably made that normal map from a texture and not from a mesh. I knew this was not right. Glad i use adblocker.

[@TheosResearchDiary]

haters gun hate. Thanks for the excellence Mr. Abbitt

[@Tuskajussi]

@@ProgNoizesB I did this for my shield and got a very good game object with 1k polygons and nice sculpted wood parts embedded into the normal map

[@soroush0700]

Thank you man

[@zardify_]

Fyi, these types of cages have since been implemented in Blender under the "extrusion" setting in the bake options. :) you only need a cage if your geometry is complex. Maybe even concave.

[@theunaimedarrow4903]

Great tutorial. My system isn't baking quickly, and messing with Ray distance was killing me. Cage worked and quickly.

[@lucashaymaker5927]

Omg this is what I needed! xDDDD

[@1lllllllll1]

Awesome tutorial, even better than blender guru!

[@grabbitt]

Thanks

[@michaels5381]

I found out that for complex objects its better to use solidify modifier for low poly cage and after applying the modifier delete the inner portion of mesh. That way you dont need to adjust manually too many faces and the cage nicely covers the high poly.

[@grabbitt]

clever idea :)

[@mws_3d]

You can also use Solidify modifier instead of manually scaling in edit mode. Should give good results most of the times

[@grabbitt]

That's an interesting idea

[@kloa4219]

Doesn't it create doubt the verts?

[@ar2chef46]

thnx mate

[@v124entkl9]

*3:48 I recomend using a displace modifier. But other than that great video

[@grabbitt]

yes makes sense

[@seanposkea]

I've been playing with Displacement, but when I use them my PC really chugs and it rarely does. For static renders, and/or arch/viz walkthrough animations are Displacement maps more efficient or is it faster/better to just have a high-poly mesh? The latter seems to be the case to me but I could be doing something wrong. Thanks

[@grabbitt]

Displacement maps are better in some way but it still requires high poly

[@apemant]

Thanks! Not easy, but it's doable. Just make sure your objects are smooth shaded (rightclick in Object mode -> Shade smooth), or you will get weird creases, at least that worked for me on my mesh (a damaged concrete wall). EDIT: If the normal map is going to be displayed on a smooth shaded mesh it should be baked on a smooth shaded mesh; and vice versa: bake on flat shaded if it will be displayed on a flat shaded object. This because the tangent space basis must be exactly the same.

[@AuxiarMolkhun]

Blender was giving me some difficulties with this that I'll explain here, including how I fixed it, in case anyone else runs into the same issue. I was following the tutorial step-by-step with no issues until it got time to actually bake the map. For whatever reason, I kept getting the error that the Cage object had a different number of faces than the Active (low-poly) object, and so it wouldn't do the bake, even though I made doubly sure that I duplicated the low-poly mesh and just scaled it up. No modifiers, no editing other than that. I was still getting this error though. Restarting Blender didn't fix it and reduplicating the low-poly mesh to make a new cage didn't seem to fix it either. What did fix it, is whenever I tried to bake it backwards. Instead of selecting the high-poly mesh first and low-poly mesh second, I instead selected them backwards and attempted the bake. Ironically, it went through, though obviously with unwanted results. Seeing as it worked this time, I decided to reselect them in the correct order and re-attempt the bake. Lo and behold, it actually worked with no Blender errors. I hope this really odd issue doesn't bug anyone else, but if it does I hope that my fix works for you too. Happy Blending.

[@grabbitt]

very interesting.

@@grabbitt I have the same problem. Blender gives a warning as low and hig poly mesh must be same numbers. Is there any way to fix it? I just followed the video and the result is as I mentioned. It just gives a warning and not finishes the nomal baking.

[@grabbitt]

@ i think you are trying to use a cage - your cage must have the same polycount as the low poly

@@grabbitt This time it is close to perfect 👍 There are some glitches but I know why are they and I can handle it easly. The big thing is I really understand the baking 😊👍 Thank you Grant Abbitt 🧡👍 After having a good baking as quaick as possible I tried texture painting but where I paint with brush it paints the other side. Is there a way to fix it?

[@FireBert85]

I think I figured out a weird quirk with Blender. If you are clicking objects with the outliner, it seems that the object you click First is your Active Object, and it stays that way no matter what you click next. However, this is reversed when clicking the same objects in the same order from within the 3D Viewport---there, you will get the second object clicked becomes the active. (v 2.83a) I tried this until my eyes bled to make sure I wasn't going crazy, watching how the object names changed colors to indicate which was active vs selected

[@willdebohun7028]

Had huge difficulty with this until I realised that in 2.9 the last selected mesh from the list doesn't become active and I had to pic it from the 3d view - thanks for all your awesome videos

[@grabbitt]

yes the outliner has changed slightly i think

[@user-ku7xp5ns9o]

thank you to share the video,I understand the useful of cage.I notice that the "ray distance",may I ask this para work outside and inside the lowpoly ?or just outside the low poly?

[@grabbitt]

outside the high poly

[@1lllllllll1]

Taking a personal note for reference: alt+s is for scaling via normals, then shift is for increasing mouse sensitivity on the scale operation.

[@draskang]

It's nice to know the basics of cage projection, but tbh, you really should be showing this on a character where you have to project into a mouth, in arm pits & between fingers.

[@grabbitt]

It would be tough for people to follow along

[@1001panoramas]

Thanks for this useful tutorial. Keep making mistakes because I learn a lot from them... and if you don't make them... I'll do make them... but I'll do'nt know where they are coming from.

[@grabbitt]

Thanks :)

[@prod.bywwhateva]

I have noticed if my low poly mesh is too low poly it will create weird jagged shadows. It took me a good hour to realise what went wrong with my bake. But on the end subdividing helped me out.

[@grabbitt]

Yeah that's more s lighting issues than mesh issue

[@RomboutVersluijs]

PS with the new tricks in bl 2.80, you can make use of the normal direction checker. If you flip the normals of the cage and than go into that view. You would clearly see item popping true because the normals are Red and Blue. Its under Overlays > Face Orientation. Quite a handy feature to use for this.

[@RomboutVersluijs]

I do hope they can some port items from baking from Blender Internal now to Cycles. Blender internal had some options which Cycles does not have. I dont see a method to bake just Vertex Colors?

[@grabbitt]

no you cant bake vertex colours any more it seems. I will try the normal's direction checker in future :)

[@RomboutVersluijs]

@@grabbitt I think i read something about using an attribute node. Perhaps it can be done that way. Im not sure if they would take such a feature out. It is possible, see here blender.stackexchange.com/questions/45964/how-to-bake-to-vertex-colors-in-blender-cycles

[@grabbitt]

@@RomboutVersluijs ah yes that makes sense I wonder how different this is from the pointiness node?

[@RomboutVersluijs]

@@grabbitt i find it weird that its a bit hidden. While BI engine it was dedicated option.

[@Titanscreaming]

This technology man ahaha. like go fgures we have to build a cage around light to set up a paremeter. - But i was thinking. In reverse, couldn't you bake in the negative direction? So your HPoly is larger than your LPoly retopo mesh and you direct the textures on the Hpoly faces down, (shrinking them a bit also ) unto the LPoly Retopo mesh? So in essence you build your retopo not around or above your HPoly mesh but within it, so it is slightly smaller. That way there are no curvatures that don't overlap strangely or not at all.

[@airbud914]

i just want you to know I love you

[@leaphymoon9881]

Do you know how I would bake other textures? I have textures and an entire node tree modifying the texture behind it. Is it possible to bake that? Thanks for the tutorial, hard to find ones as good as yours

[@grabbitt]

Yes it's possible to bake all textures i believe apart from animated ones. Search baking on my channel and it should come up with the other tutorials I have created on the subject

[@drjarman]

Hey! Great Tut Grant! I'm wondering about an issue im having while following along. When baking, both my objects (HP and LP) are shaded smooth but when the Normal map is generated and then applied to the LP model the shading seems flat/sharp. Any ideas?

[@grabbitt]

that's a new one for me. have you got any doubles on your high res?

[@drjarman]

@@grabbittThanks for the reply! Blender just needed a restart. Not sure what the issue was. Thanks for your help! I look forward to your next tut :D

[@tris0913]

baking hard surface textures for substance painter (NOT MESH just the painting normals): deselect 32bit float and leave at sRGB

[@BreakMaker2904]

Unnfortunately, I have encountered an issue that makes the inflated cage approach as introduced in the video unusable. When I use alt+s (shrink/fatten) to scale the cage along the normals, some vertices and faces get deleted! My low poly has 66 307 faces, when I fatten the cage so that it covers the entire high poly model only 66 305 faces remain! As a result, when I want to bake it stops with an error that the poly count must be the same... Any ideas, Grant, how to go about this? Using "max ray distance" gives bad results, because the high poly sticks out from the low poly.

[@grabbitt]

i've no idea why that would be sorry

[@MarkoDijan]

I just encountered the same problem. The thing was that my "Auto Merge Vertices" was ON and while scaling some of the vertices came too close and merged. Check if you did the same mistake and just turn it OFF. That should solve the problem :)

[@BoboTheImp]

Any particular reason you used Alt+S instead of just scaling the cage? Does it have to do with the origin?

[@grabbitt]

Alt s scales on the normals if you have a more complex object it makes more sense.

[@kray3d]

When baking, you dont need to unwrap the high poly one correct?

[@grabbitt]

indeed

[@cabreram.4734]

There's no uv unwraping needed for Hp or LP? Edit: sorry, I jumped the gun😅

[@adelinacool]

I've been trying to use this method to make normals for a big object (make out of multiples ones that i joined together) but for some reason, I don't get normals for like half the stuff in the scene. any suggestions?

[@grabbitt]

could be a number of issues but mainly check face direction

[@skilat193]

Can we use a shrinkwrap modifier first or it's better to don't do it for a cage ?

[@grabbitt]

Yes that works as well

[@chrissem5200]

Hi. Do you know why my normal map have some blury spots in it and why it has a blury streched outline which isnt a part of the texture map.

[@grabbitt]

Not sure. Does it work when you put it on your object?

[@guidodingemans]

Hi Grant, thank you for another excellent tutorial, extremely helpful! My normal maps look much better when I use cages. Forgive me if this is a stupid question, but does the size of the cage actually matter? Like, the tighter it fits around the other meshes, the better? Or will the results be the same, no matter how tight or loose the cage fits?

[@grabbitt]

Tighter fit is more accurate

[@guidodingemans]

@@grabbitt Thanks for replying, much appreciated!

Silly newbie question. Does the unwrap method make any difference to the outcome of the normal map
