RenderTexture limitation with WebGL?

Unity Engine

I have a weird problem since we started with WebGL (january).

Is there a RenderTexture limitation with WebGL?

I have 2 render texture (asset not temporary RenderTexture)

128x128 / ARGB32 / 24 bit depth buffer
1024x1024 / ARGB32 / 24 bit depth buffer

I render multiple mesh and I use that after in a RawImage. On all other platform, the alpha work. But on WebGL there’s no alpha on the 1024x1024. But the 128x128 the alpha is correct.

Is there a limitation the size of the render texture? Or it’s supposed to work?

There is no reason known to me why this should not work. I suggest filing a bug report with a repro case.

It’s not related to the size of the render texture. It was hard to reproduce from scratch. The problem happen with 2 camera created at runtime. I filed a bug: 719438.

there is no known issue related to render textures at this point. Does it work on GLES platforms?

Just happened with me as well, two cameras (but at the same display) but getting the black screen as result. Not happening on standalone builds.
