Hi everyone.

I'm making a 2D platformer and quite fascinated with what Godot engine is capable of. 

But now I'm on a struggle bus with some shading issues.

On desktop my 2D shaders seems to work quite well.

However, when I'm running my game on Android device they are gone.

I'm receiving the following messages from ADB whenever my shader should activate itself:

All shaders are implemented within materials for the TextureFrame nodes.

Here's the example of one that doesn't work:

// this is a simple texture-based Vignette modulated shader uniform texture vignette; uniform float lightness; uniform vec3 modulate; vec3 screen = texscreen( SCREEN_UV ).rgb; vec4 tex = tex(vignette, UV) lightness; // combine final color color res = color( tex.r, tex.g, tex.b, tex.a); res.rgb = mix( res.rgb, _screen.rgb, lightness ); res.rgb = modulate; COLOR = res;
