Texture Atlasing for VRChat

In this video we will cover the basics of Draw Calls and close with Atlasing!
This will facilitate a smoother experience while socializing on VRChat.

Very to the point, impressive

Did my best, it was a lot of work to be as concise as possible! Hope it helped :)

Question, is texture packing the same as what atlasing is? I'm using substance painter and have got pbr maps split up with multiple material slots, trying to understand if there's any differences or differences in usecases between these two terms or if they're just the same thing with different terminology?

[@SwaMusic]

Ah, excellent question! Atlasing is the process of taking multiple textures and combining them into a single texture. Packing, is the process of taking all the data maps(AO, Roughness, Metallic) and "packing" them into R/G/B channels rather than using 3 separate textures in those respective slots. You end up with greater file size and wasted channels if the shader doesn't support excluding them at runtime. I should make a video on that topic next! :)

We'll all be wearing blocks soon. Was'nt virtual reality supposed to be high fidelity and immersive? Why are we going back to roblox? When does it fall upon the user to actually upgrade their hardware?

[@RunicRasol]

Short answer to this is that VR Chat needs to keep growing a larger and larger userbase. They got all the PC & PCVR users they could get, then they got all the Quest users. But they still need more, so they made the app available to smartphones & tablets. Despite all the dunking people did on the Quest 2, the thing is an absolute monster in terms of horsepower compared to an iPhone or an iPad, so they had to lower the requirements even more to make it so the mobile users could still use the app.
