Are Texture Arrays supported?

[DevIsDave]

Hi,

Just want to enquire whether texture arrays are supported on WebGL 2.0? I know the manual says it is supported, and SystemInfo.supports2DArrayTextures returns true when run on WebGL, but the creator of MicroSplat believes it is not supported and hence why MicroSplat does not work in WebGL (it does in the editor, just not in a build).

This is the error been thrown in WebGL, don’t think it’s a texture array issue but thought I’d share in case it is something on Unity’s WebGL side anyway.

exception thrown: TypeError: Argument 8 of WebGL2RenderingContext.compressedTexSubImage2D is not an object.,_glCompressedTexSubImage3D@blob:null/4a382246-6107-6b4d-9ed6-e01c080e3867:3594:7

Thanks.

which version of Unity?
Have you tried 2018.2? If that persists, it would be great if you could submit a bug report.

Yes.

Actually, I remember this issue. It used to be a bug in emscripten. If you upgrade to a recent patch/version of Unity it should be fixed.

Ah perfect, thank you Marco!
