Hey! Looking for some optimization magic here! I have a character customization system where the player can pick out clothes (shirts, pants, shoes, hats, etc). All of these items have their own material slots, which means each have their own draw calls. Is there any way that I can get the materials from the items the player picks and somehow merge them all into a single material so that there is only one draw call? Or at least reduce the amount of draw calls to an extent.

I don't even feel this method is optimal to be honest

Hey! Looking for some optimization magic here! I have a character customization ...
You could build your materials around a common patent and just merge the textures into one new render target
You. Could use a big virtual texture
You could use texture array
The character merging plug-in I'm using allows you to shift or scale the UV per mesh
So there are a lot of ways to do this depending on how many different things you need to account for

fair but i feel like it's a really good gateway video to get into material optimization with how beginner friendly and in depth it goes

Make a big Virtual Textures, youβre looking for a UDIM, and manipulating the bigger part of the UV values so that you can select the texture.

Yes that's what I was suggesting
But if you use mesh merge you literally don't need to change the material at all
All these characters literally have this material
There is no math, a single texture sampler
And they can be produced in many combinations
Probably some 4 thousand something combinations I don't remember exactly
