How to use KTX2 / BASIS compressed normals

[bghgary]

@Dshah_H

I encountered few warnings for POT like: “warn: Texture dimensions 512x367 are NPOT, and may fail in older APIs (including WebGL 1.0) on certain devices.” , I presume it is necessary to correct those for better performance , right?

Yes.

@Dshah_H

I have created some standard /custom material texture in babylonjs, which are not embedded in GLB model , how would I go about to compress them? (I couldn’t find a command for this on glTF-Trsnform)

I’m not sure. Maybe ask on the GitHub? Issues · donmccurdy/glTF-Transform (github.com)

@Dshah_H

in above commands you are only using baseColorTexture , should I also process on other texture types?

The commands I sent will compress all the textures. Only the color texture uses ETC1S where as everything else uses UASTC.

@Dshah_H

what are these parameters for? --zstd 22 --slots and which other parameters are available? couldn’t find in docs.

--zstd specifies the zstd compression level. --slots indicate which texture slots to apply the command to. I’m not sure. I got this information from Don

@Dshah_H

are there some other helpful commands to process my model from glTF-Transform?

Seems like you got all of them.
