I have never seen the transferring normals. Thats dope.

Cool video buddy. FYI, you don't need to add the cast modifier to spherize a cube. You can just hit Shift+Alt+S and drag the mouse in object mode.

[@JoshGambrell]

Ah perfect! Would've been a lot quicker that way, I just never have to do it in vanilla

[@DECODEDVFX]

@@JoshGambrell Slight correction. You do it in edit mode after you apply the sub-surf. Still usually faster though compared to manually applying the cast.

How would you model a cylinder that transitions to a hexagonal section and back to a smaller smooth cylinder with a rounded top?

[@zarajwong]

As a teacher, I have to commend you on your natural ability and gift for explanation. Your approach reminds me of Richard Feynman. I appreciate that you take the time to explain the reasoning behind your decisions and not simply how to accomplish something. I am new to this and i have lamented that there are few videos available that discuss principles of 3D . Your lessons address how to think about the process of modeling and the relevant considerations . You are a great introduction to the subject. I see from your work that Im learning from someone who is accomplished. Keep teaching ! Thank you.

[@JoshGambrell]

Ah thanks a bunch Travis! Fortunately it is an innate skill for me and I am so happy I can use it to help others. I also do the EXACT opposite of 90% of my College professors... lol. Most are genius but simply cannot teach.

Great video, in particular because you showed the vanilla way. As a student/pupil who doesn't earn any money with blender, add-ons are usually out of one's budget.

[@gorans007]

Man thanks for showing us these, finally some proper tutorial to show me the real problems and not to just looking for bunch of tutorials where they won't give you any information like this, which for me this is so important. You have no idea how much videos and tutorials I was looking for to give me a proper explanation about this and I can never find anything close to this. I am 3ds max user, but I guess i have to change my workflow to Blender and get these things more easier.

@@JoshGambrell so glad to see such an great quailty of the vedio ! but one thing makes me wonder that when it comes to model a car and trying to make a panal gap on really complexed curved surface, the way shown in this vedio could also be a solution??

Great video as always Josh. The knowledge you give away for free is incredible. And to the people commenting on the cost of add-ons: If you have HardOps, Boxcutter, Meshmachin3 and Kit Ops you’ve got the best set of modelling tools for less than £150!!! You can’t even rent Cinema 4D for one month at that cost 😂😂😂 Plus you get FREE tutorials from Grant Abbit, Josh and Ryuui, Masterxeon to name a few. Blender users are the luckiest in the 3D world!!!

[@JoshGambrell]

Thanks a bunch Chris! Anything behind a paywall will unfortunately always have controversy, so I try to find that balance between showcasing both the vanilla workflow and addon workflow so people can learn fundamentals and find their preferred modeling strategy :)

[@DarkAutumn3D]

I admire that and I'm the same way. Even as an experienced 3D model artist myself - I still run into problems and have to then think outside of the box to come up with ways of fixing it. I think there's often a stigma that, once you pass a certain level, you can literally model anything without a single hiccup. I find that it's just unrealistic to think that way and you'll always be learning from little mistakes and hurdles. That's why I enjoy being a 3D model artist. There's always little challenges that help you to better yourself.

[@fransomoza2399]

Dude, I just love you for this, its been many hours trying to fix a damn mesh with booleans and this data transfer thing is the shit thanks forever ❤

[@abrahamwondafrash7549]

even out, the cutter and source object is a very helpful method!

[@FlickerJab]

I believe you can shrinkwarp the vertex group on the second sphere to get the same results. Shrinkwrap and this method you just mentioned are the best workflows to use when cutting holes and creating creases in car modeling. This is a very interesting alternative, good stuff as always, thanks man.

[@JoshGambrell]

Thanks a bunch! Yeah, shrinkwrap is awesome, especially when using the conform tool built into mesh machine.

[@kolupsy]

he talks about intuition when it comes to merging verts when cleaning up. i think the best way to to merge towards the vertex thats not on a straight line. if you merge a vertex, that is on a straight line towards a vertex that formes an angle with the others, you keep the right shape of the cutout

Useful tutorial. But... I couldn't follow what you did, starting at 4:58 where you slide the vertex along the edge to a nearest vertex and (apparently) automatically merge it. In the keycast all I can see is that you are hitting G ...!? How is it done? Thanks. OK - I think I found the answer to my own question: the symbol to the right of Mirror XYZ option is ticked on, and that means AutoMerge On.

An alternative way to create a Quad-Sphere is to just "Shift A" - Add a "Round Cube", then under the "operator presets" dropdown menu, just change it to a Quadsphere

[@rudranathmistry6957]

I think this quad sphere increases geometry. Rather I use uv sphere and rotate it to the position where I remove the upper triangle loop by Boolean. Circular Booleans really fit well an minimize artifacts on bevel

I usually do voxel remesh and smooth corrective + sculpting and then remesh again. By the way if for someone bolians crash blender - Houdini Apprentice (Free non commercial) works fine with them, even if its procedural noise erosion with crazy ammount of polygons.

[@kacperwojcik4794]

One question. When I use built in option, merge by distance in cleanup menu. I'll get the same result? I'm talking about that moment, when you merge all the vertex manually in 5:29.

[@tricky2k]

When you move the vertices, the spatial position is respected? I mean, the place (x,y,z) where it should be without messing the geometry

[@milkndsugar]

I like doing Ctrl shift - more than Ctrl - since it deletes the area that the boolean mesh is in rather than making the boolean mesh always be doing cuts or whatever it does, then I extrude inwards and join those vertices

[@viktorovich27]

is there a drawback somewhere down the road for using the data transfer trick on a low poly mesh/high vertex count cutter instance?

[@keithlewis255]

Great video Josh, thanks man! Mine ended up with more triangles than I wanted, but was still very smooth... and overall the normal face data transfer REALLY did a nice job on the surrounding surface! Tips and techniques like these really make learning a lot smoother. I appreciate your knowledge and dedication.

Thanks Keith! My pleasure!

[@ollie4859]

thank you so much josh your tutorials are really helpful！

[@spartan.X]

You can also, (For the destructive modeling team), do a manual subdivision and use Mesh -> Transform -> To Sphere, It does the same job and it's already applied, and there's no size modification (wich is the case when using the subdivision surface modifier). Hope It'll help ^^

[@shawnhollahan590]

Thank you Josh for the great tutorial. Interestingly I'm trying to apply multiple round cuts in a cylinder and the vert process is more complicated. The cylinder is made of long stretched quads that make up its wall. There are no verts to move to create a bevel. When I shade smooth it looks awful even though I've followed your suggestion of matching vert density (between object and cutter) and cleaned things up. I'd love to see a follow up tutorial in which you do this process to a cylinder, cone, torus, etc. FYI... I'm mastering Blender for the purposes of Scientific Visualization and Presentations. I'm getting pretty good at Blenders basics (interface, tools and workflow) but now am mastering the details of modeling and next animating. I'm building a syringe that ejects a rice-sized capsule that has two rows of 6 holes, each hole carries a different drug. The capsule is injected into tumors and then later it is removed and doctors examine which drugs, from which holes have had the best effect at killing the tumor. So... accuracy of my model, realism and zooming in and out of scale (to show tiny capsule in detail, then zoom out to show full tumor and animating the process) I'm also having a hard time finding tutorials that teach array-modifiers that can create cellular architecture (molecules, proteins, cell walls, cell interiors, etc.) ...any tutorials in that direction would be greatly appreciated. Thanks for considering.

[@JoshGambrell]

Hi Shawn. First off, very interesting stuff you're working on! Second, my guess is that you have just a basic cylinder with no holding cuts. You need to add horizontal cuts as well so the shading doesn't stretch. The topology where the vertical cuts meet the horizontal cuts should roughly be square shaped if you want a decent amount of geo. Here is a great tutorial from my friend Ryuu: kzbin.info/www/bejne/bYi6pZuKh9SXpc0 and one similar one that I made: kzbin.info/www/bejne/gJClnYJ4mZyKrdE&t Best of luck!

[@mazashayeri1411]

That was a very useful tip. Thank you! By the way what do you think about the zebra strips mat caps? in my opinion they show the shading issues pretty well. I saw people using them in Rhino3D to review shading issues.

[@xstasis]

[@nook1e.]

Do u use shrink wrap modifier? I watch some guides and it helps to deform shape almost the same way

[@count23all]

Your shading errors came from the edge slides deviating the surface when you moved them around as part of your cleanup, the mat cap is a Class A surface. The trick is that you need to push the verts back _into_ place to restore the curvature of the sphere, that will also resolve your defective cut without using the normal transfer. An easy way to implement this is to shrinkwrap the cut surface onto a clean surface without the cut, and let the shrinkwrap modifier push all the verts back into place that you knocked around for you. also, another fix would have been to apply a bevel with a profile of 1.0 first to create effectively a reverse inset around the cutout evenly spaced from the edge, then the shading issues would have been confined via that created control loop and the cut. The low res cutter problem can also be resolved by running to "tosphere" operation on the edge loops once the cut has been done, it will realign the high poly edges and let you have a low poly interior of you really require hard edges.

[@JoshGambrell]

Yeah, this is precisely what the conform tool does in mesh machine, but I wanted this tutorial to be in vanilla and I really can't be bothered to fuck with the vanilla tool set for some of those shrinkwrapping operations when it's 2 clicks with MM. But you are correct about the shrinkwrapping being an effective solution as well.

[@count23all]

@@JoshGambrell All good, I'm just suggesting that the shrinkwrap is a faster and less confusing way than the data transfer modifier at the end there to clean up the shading issues. One click like a bool and apply, it'll restore vert positions and achieve the same result, theoretically a bit more noob friendly. I fear that the data transfer modifier will confuse people who undo a cut later and aren't away of having to clean up normal data to be able to do any further work on the affected faces.

[@Keilnoth]

@@count23all what you are saying is, if you then move the boolean around or remove it your normals will be f*cked? Can't we just re-transfer the normal data again from the base sphere?

[@count23all]

No, it's a bit more complicated than that. If you never apply the data transfer modifier and keep booleaning away, it'll work fine for you and update the modifier as you go. However, if you apply the modifier and start moving verts around, even if you manually clean up the boolean to make a sphere again, or even just manipulate the edges of the cutout (to create a bevel) without the transfer modifier in place or a "guide" mesh for hte modifier to work, the verts, edges and faces will retain what's called "custom normal data" which needs to be cleared for shading to work properly again. A far more effective way is to use shrinkwrap instead of data transfer, it means the verts, edges and faces will not be getting this custom data and for newbies to the software who may not be familiar with the concept of normals or split normals, it's easier to managed and troubleshoot. Because using shrinkwrap instead, your vertices are being pulled into the right spot for the shading data they're using, rather than using shading data that overrides their normal one.

[@Keilnoth]

@@count23all OK, thanks for the info. Well it's interesting to learn both methods. I will have to dive into the shrinkwrap stuff again. I think Josh has another video covering that one. I use MESHMachine also but I prefer to understand what the add-on is doing so I know how to fix things myself.

Well, I've been at it for around 7 years now, but I think it's less about the timeframe spent and more about the hours and dedication put in. My good friend Ryuu started 3D just over a year ago and is at my skill level now, if not better. Someone could work for a decade on and off and someone could work fora year non-stop, and the guy working the year may be more competent with the software :)

[@millie2079]

You definitely get better the more HOURS you consistently put in. I’d been messing about with Cinema since about 2015, just a few hours here and there and never really got anywhere. Then last year I wrote a list of projects and time permitting I put in as much effort to tick those projects off a list. If I’m fortunate to be able to work on a project every day I can finish one in a month, but when I’m super busy with work and family it takes ages. I’m switching over to Blender now though so it’s taking a bit longer but soon I’ll be up to speed again. blender is 👍🏻
