Compressed Textures in WebGL?

15

I have not setup Android compilation successfully, only tested via WebGL. Can you therefore try to add some trace like below into openfl/_internal/stage3D/opengl/GLTexture.hx in uploadCompressedTextureFromByteArray?

replace:
var format = GLTextureBase.__compressedTextureFormats.toTextureFormat(alpha, gpuFormat); if (format == 0) return;
with
var format = GLTextureBase.__compressedTextureFormats.toTextureFormat(alpha, gpuFormat); trace("gpuFormat: " + gpuFormat + " format: "+ format); if (format == 0) return;
