Support WEBP for textures #65

Closed nicolasayotte closed 4 months ago

nicolasayotte commented 1 year ago

WEBP offers full transparency support (32-bit) and is very space efficient as compared to PNG.

But, I mean, only if you think 80-95% smaller file size matter in web.

I dont know how to encode webp textures... is there a C# WEBP encoder I can use from Unity ?

Nice!! Will test and come back to you

MackeyK24 commented 4 months ago

Shit, I forgot to upload the new builds... So re-download to get the latest WEBP update.

Which I love now, I use the WEBP options all the time...

Note: Lightmaps, heightmaps and splatmaps are still exported as lossless png to main pixel precision

I default color maps to -q90 and normal maps to -q10

Yo @nicolasayotte

Checkout the built in compression support for webp compressed textures and gzipped gltf scene files

https://forum.babylonjs.com/t/compressed-interactive-unity-gltf-content/50105

Here is a demo playground using full compression where its possible. Lightmaps, heightmaps and splatmaps still use lossless png to main the pixel precision needed for hdr lighting and terrain texture blending
