BETTER PERFORMANCE in Blender with the Decimate Modifier!

[@TheCGEssentials]

Hi everyone! Let me know what you think about the decimate modifier in the comments below! :)

[@MysteryFinery]

@thecgessentials sorry for the off topic question but do you know how to import fbx with imbeded textures? opening the file does'nt show any textures..

[@dzomlamasina1560]

Great video and tutorial. I think im winner of all sub problems 😂 I make mushroom and sub it 2 times i copy it i 6 mushrooms and make colection,that colection i copy 15 times and that 15 times i copy 3 more.times.. 3x45 + x6 more mushrooms ..810 copied mushrooms with sub lv 2 when i opet decimate modf it was in 1 colection over 4 mil faces and i got 3 colection,that was 12mil faces my pc crash and blender 😂

[@chocloretin]

It's so cool!

[@rosalioinojosa]

It was really helpful. It was exactly what I was looking for. I wanted to upload a model to Pepacura to make a real 3D sculpture and the only way to do it was to decimate my model to get way fewer faces. Thank you, man.

[@KyleHart-m7n]

Wonderful! The way you actually take the time to explain everything in your videos is awesome.

[@kayosiiii]

For game models to get the most optimal results use planar, with the option that preserves your uv seams. Then select an angle that gives you an acceptable amount of detail. Place a triangulate modifier after.

[@danieljolani3404]

This is actually such an under appreciated simple step to stop blender crashing...while everyone is focused on cutting down the esthetics...ur chopping down the base structure...well done buddy!

[@jklwjk]

I notice every time I need some Blender info I end up coming back to you. Concise and clear, thank you. I was panicking about what I was going to do with my model that caused Blender to slow down severely. I used the decimate modifier and brought it down where it still looked good. Now I can even use duplicates of the object in my scene. Thank you, thank you, thank you!!!

[@Kimmy_Nami]

I just made a 3D scan for the first time in my life, and was figuring out how to make it smoother. Thank you for your tutorial!

[@wendysbrian1]

Whoah that PLANAR method just stopped me from ripping my hair out man. I was stuck trying to do UV work on a model that had waaaay too much topology, this is way better. You are a life saver. THANK YOU!

[@xtremegamemaker]

Thanks bro. I had downloaded a terrain model for my game in python and it had so many faces even my rtx 2070 super couldn't handle it. This saved my life (and my computer) today.

[@TheCGEssentials]

Awesome - glad I could help!

[@clairestrickland5140]

Thank you, really helpful. My mesh was so huge from Rhino 8 shrinkwrap (me not really thinking about what settings I was using), so needed to jump into a quick and helpful decimate tutorial. Thanks so much! My first time using Blender.

[@cheshirecatproductions]

Explaining the plane modifier saved so much time and effort on my avatar.

[@Kyle_Butterfield81]

thanks for the info. i'm super new and i brought a model in to here with 16m triangles from nomad sculpt and it took forever to load and then decimate the model. I appreciate your instruction!

[@billywhitaker6658]

Are you me? Lol

[@Cferg]

I started using Blender in the last month. You’re videos are a wealth of knowledge.

[@penelopesaladfingers426]

i love you for this - it made staying up till 3am fretting about a messy 2m triangle mess of a scan - wondering how i'd ever get anywhere with my pc moving at the rate of a snail , well worth it , thank you , your tutorials are spot on.

[@donsorenoelchapogringo1182]

This is really helpful for game assets, especially creatures which are difficult to edit after subdivision surface and triangulation has applied.

[@TheCGEssentials]

Exactly!

[@stevejones9044]

What a completely clear and easy to follow and understand tutorial!

[@aliceleblanc7318]

Thank you for explaining all 3 decimate options! Saved my life! :D

[@mysterious_monolith_]

That was ABSOLUTELY BRILLIANT! Thank you! I didn't think a newb like me would be able to understand this but I do! You explained it so clearly.

[@kevindomara]

Thank you so much! This is exactly what I needed. Very clear and understandable. I watched 2 videos before this from other people that I couldn't understand.

[@raccoonicorn3172]

this has helped me so much with Importing my avatar onto the Quest. Thank you!

[@SHEMZILLER]

Best tutorial on KZbin

[@The_Ninedalorian]

Your tutorials have helped me immensely. I'm creating an entire new furniture replacer set for Skyrim. Log Furniture! Because Nords you know

[@Deleted1794]

Do you not know who frecken helpful this is! Dude thank you! I always use subdivided to make my models but everytime I use it to animate it the bones never actually connect but because of this not only the model doesn’t change but it still looks nature! So thank you! Now my computer runs easier and faster, truly thank you!

[@LisaMurphy]

So I notice that when I go into edit mode to delete some things all the original vertices show up again. It makes me wonder. So all of the original geometry is still there, so what is really being accomplished with decimate? Does this mean the rendering will go much faster? As far as just working with the environment in the layout mode, I don't really see a difference in performance. I hope it does help in rendering time.

[@MaiaCoimbra]

Congrats Thanks and that Silves One of my issues with my models regarding maintaining the UV Maps ,Many thanks again

[@WalkCareful]

Thank you CG for the best explantion of how to get vertex's numbers down, these other youtubers beat around the bush! you kept your vid/instructions simple and short, this helped alot man big ups

Dude this was so helpful! Had a scenery with a terrain that had about 5 Million faces (I don't remember what happened LOL!) and I turned the Collapse ratio to 0.1, and now my .blend file is about 155 MB instead of 855 MB! And the terrain looks the same as it wasn't even touched! Thank you so much for this tutorial, I will use this if this (God forbid) happens again!😁👌

[@EIendir]

Great JOB !

[@ThomasStevensontutor]

Thank you sir, this was really helpful! I appreciate how you compared the different methods of decimating and their effects on pre-applied materials. :)

[@frankrussell9489]

Oh cool I need to reduce my 211MB STL to just under 100 MB but retain enough detail. I will explore the decimate feature. My artist made this guy and after smoothing it got up to 211 MB. Thankyou Thankyou!

[@morielpereira4299]

I know there're 100k vertices still, but now as it is decimated, can you rig it and animate it? or like you have to retopologize it, bake the maps and then rig the low poly textured mapped mesh in order to animate it? plz don't say yes, my pc has a graphic card from 2014 btw, lol

[@iaskedaitodoit]

Do you need to apply the modifier to spped up the viewport performance? my observations are you don't need to, but I'm not sure

I would have liked to see the wireframe on the "Bonnie" model when you did the different Decimations. Thanks for using that model, btw. I've been watching a lot of Blender tutorials lately, and the "Suzanne" Monkey face is getting pretty tired. (c:

Nice tut. thanks

[@user-kp4cn5hn5y]

After I add decimate modifier and change the bar, nothing happens

[@fabiansantiago93]

Wow thank u very much this save me a lot of time. I am using blender to import models to a lighting software so with lower poligons it makes the calculation so much faster. Also I have a question is there a site where I can find simple 3d models already made, like chairs, tables, trees, display furniture for shops?

[@TheCGEssentials]

Sketchfab or Blenderkit

[@bitsurface5654]

You will get small (black) triangles when you do this. This is due to the UV map which is also reduced, and blender do not know where to take the texture from. It is also good to have two (objects) of them an rebake the Texture from hi to low poly so you can get rid of the black triangles.

[@TheCGEssentials]

I didn't get small black triangles when I did this, so...

[@bitsurface5654]

@@TheCGEssentials ??? Maybe it depends on the UV map? I tried this with a Meshroomscan.

I've imported a model from Zbrush but decimate doesn't seem to do anything. The numbers aren't going down either. Is there a way to solve this?

[@TheCGEssentials]

Are you sure you applied it to the entire Zbrush model? Is the Zbrush model in different parts?

[@kiwinesss]

Use the ZBrush decimation before you import into Blender.

[@florijanftw]

I did all this and my whole file only reduced by 5 % why is that ?

[@GeotrxIsSwaggierThanYou]

mine doesnt say add modifer how could i get that to pop up?

[@Sorra1-Mods]

can i have the Decimate object in the Edit mode? I mean when i have a model with many tris and would like to reduce them with this modifier. Can I somehow bring the result into edit mode so that I can edit it further manually? Because if I go after the video and then switch to edit mode, in edit mode it has the original model (with the original amount of tris) and only in object mode does it have the reduced tris that I reduced with the Decimate modifier.

[@bhoffman1967]

very helpful video, but there is something you didn't going into that is killing me: I can only apply a Decimation to items within my collection that have the downward facing triangle icon next to the item, not the container (?) item with the 3-branch icon. since I have over 3,000 item in the container, apply a decimate to each item in turn is not an option. Help?

[@normg2242]

very helpful, thank you :)

how do i combine mesh into one big mesh so it wount take to mutch of my pc power??

[@joespadaford8736]

I use decimate often when I bring in models from Adobe medium. It’s a massive struggle to retain what looks like simple geo for some mud brick looking houses I am making for some villages. But when I decimate. To get even simple looking meshes of homes down below 500k polys homes always start to look like melted butter. It like the trade of for voxel work is either work small or have a scene that looks like melted butter. I wish decimate kept hard edges

BIG HELP 🥰

[@mehildemeh6907]

Thanks for posting this tutorial on the Decimate Modifier. I notice you joined all the objects before using the modifier. Is it possible to apply the modifier to different, unjoined meshes? For instance, a Decimate Mod for the horse's mane and a separate modifier for the robes, resulting in a reduced edge count for the densest part of the mesh.

[@TheCGEssentials]

Sure - they just get applied to the individual meshes as you add the modifier - not sure how they'd look when they run into each other

[@Hunterunt]

This creates rips in my model. Is that preventable?

[@Hunterunt]

Nvm, planar doesn’t do this

[@janlos202]

veery good video!! TXH!

[@adamarcher7847]

great vid, thanks!

[@lindariccijacobs]

Is there a way to decimate, but mask part of the mesh where you want to keep a little more detail?

[@AhbibHaald]

You can split the mesh (not in practice, just so that the inspector considers them 2 meshes) and apply different modifiers. You can ask on r/blenderhelp if you want more info

[@DeWessel97]

you can also select the vertice/faces you want to decimate in edit mode, go to mesh > clean up > decimate to reduce the amount of polys only on the selected area

[@Spicypaprikaband]

Nice thanks a lot !

[@RodieOsc]

The problem i have is the Hair exported from Daz3d it has so many polygons like one piece had like 2 million so it would crash the program at times

[@Kralkuscov]

I have a question however I am unsure what exactly to ask for when going on public forums, for example I have some models I've ripped from old games I used to play and wanted to do some non textured Blender art but the only way I can make the rips/meshes look really nice was to use the flat shade thing and now there's a bunch of individual flat faces/edges or whatever it's pronounced and I have no clue how to keep the overal amazing look but making the edges/faces flat/smooth it's weird I guess.

Well your file size wouldn't change unless you applied the modifier because an active modifier doesn't change the underlying geometry
