Godot 3.1 GLES2 not working

[websterek]

Sadly Shader is not working with GLES2 in latest Godot 3.1 :(

For reproduction perfect is provided in repo example file and changing GLES version.

Greetings!

If it works in GLES3 but not GLES2 then it probably isn't supported by GLES2 (probably because depth texture isn't supported). Otherwise, it's an engine bug, which I doubt.

[leopoldek]

Another reason could be because textureLod(...) is not supported in the fragment shader.

Ah ok it seems its because inverse(...) is unsupported in GLES2. I might be able to modify the math to get rid of it but no promises...
