How to make an Atlas in blender(2.93)

[@instantworldfacts4382]

this is super amazing, super informative, to the point, Thanks man

[@fmmustafa]

If ive udims means 7 diffuses 7 normals and 7 roughs , then how can i make atlas for them

[@callmemarc5274]

so ive made the atlas should they still be seperate meshes?

[@loafers9214]

You should make an underwater avatar

[@kelsiesutton4532]

I'm conufued how to do the alpha version. Please could you make a follow up video regarding this or explain how I can fix this as the head I'm using uses an alpha, yet the body does not.

[@soviet_ren4412]

depending on what it is you can either use a cutout or leave it its own material and use something like fade or transparency

I am not sure why you say that bigger textures are less optimized and we should avoid 4K textures. A 2K texture has 4 time the amount of texels as a 1K texture. That means you can losslessly atlas four 1K textures into a single 2K texture. A game engine would generally prefer to have 1one large texture over multiple smaller ones, because a single large texture can be looked up within a single draw call, while having multiple smaller textures requires splitting the rendering of your model into multiple draw calls - one per material used. More texture sets (individual smaller atlases) = more materials = more draw calls = slower rendering. Unless you're atlassing textures very wastefully leaving lots of unused UV space or you are atlassing lots of objects that are not going to occupy the same space (making the engine keep the whole atlas in memory, while you render using only 5% of it or something like that), it should always be preferred to use a smaller number of larger textures over a large number of small ones. Is there something I am missing here?

[@soviet_ren4412]

No you are generally right but textures are logarithmic, as well as draw calls are upon initial load, but having really big textures causes the gpu core to be used quite a bit more so it’s a balancing game between cpu and gpu which one you want to stress more

[@soviet_ren4412]

As well as if you atlas say a 256 texture in a 4K body then you crunch that texture in say unity too 2k that 256 texture becomes unrecognizable

please help mine doesnt give a propt just says duplicates have been combined

[@soviet_ren4412]

Could you elaborate further on this as I’m still a little confused as to what the issue is

[@egmachine]

Whenever I try to create atlas it doesn't give me the option to save somewhere. It just seems to make the one texture and apply it to everywhere that was selected

[@ellitheloser]

same

[@kyotokira2589]

do you perchance have a alt link to the material combiner plugin? when i press download mat combiner it says vrchatclub cannot be reached.

[@bloom-mania]

yeah it seems to be broken unfortunately as i also cant download it

[@kyotokira2589]

@@bloom-mania I think I got around this by searching it up on Google And that was able to pull it up, So if anyone asks in the future hopefully that helps c:

[@fmmustafa]

donno why but when i got to setting tab where we set custom resolution , its showing image size 32px by 32px , though the texture size is 2k, then why its showing 32px,

[@soviet_ren4412]

Double Check the texture size try reimporting restarting and making sure read only is off on the files, I personally have never had this issue so I do not know the proper solution.

[@lemythologia4315]

Hello, After carrying out all the required steps, the list of materials does not appear (neither in "cats", nor in "material combiner"). What should I do please? Thank you very much.

[@soviet_ren4412]

That’s a very interesting problem, unfortunately I have never encountered the materials not appearing. Try 1. Reinstalling blender and all plugins 2. Making sure you have the correct versions for the plugins, what I recommend is 2.93. And lastly make sure you didn’t miss any key points in the video.

[@Eddiemation]

I’m having the same issue. There is also no button to update material list.
