Hello, I am on a journey now optimizing for a web game I’m making, there are many steps to get entities scaling up and I’m trying to tick the boxes where it will count. My solution for entities en masse that share the same model but varying textures (a plate breastplate vs chain, a polar bear textu…

Side question: has anyone experimented with compressing VAT textures? Those things can get huge!

cc @alexchuber I’d love to see this feature in the engine honestly :slight_smile: Would you be open to do a PR @knervous ? Maybe with Alex’s help

After getting some results across different GPUs it seems like even when mapping engine capabilities to the basis compression type there ends up with some bad sampling, so it seems like it’s not a given that this could work right out of the box… Also in a bit over my head here maybe :slight_smile: I…

Wow, this looks awesome! That’s a significant difference in memory. As you’ve probably noticed, we don’t currently support 2D texture arrays in our basis, ktx, and dds loaders-- only 2D and cube textures are handled. I believe these loaders actually predate, or nearly predate, texture 2D array supp…

Thanks! Here’s an updated PG with some preflight config for the basis transcoder to tell it which formats to try to transcode to… Babylon.js Playground Babylon.js playground is a live editor for Babylon.js WebGL and WebGPU 3D scenes Not super familiar with …

Thanks @ryantrem - so cool to see you guys knocking down the dominos of the past so quickly, and it’s great to see the array handling move into the decoder/engine rather than requiring private engine patches. I eventually worked around the original gap downstream in Shado/Requiem. The assets are mu…
