[Solved] Error with ContrastAdjustmentFilter in Android

Troubleshooting android
1

Hello everyone…

I am creating a game for android, I tried to use the ContrastAdjustmentFilter so I run my game on three different devices, on one it works fine, but on the other two it gives me the error below, does anyone know how to fix it?
I really don’t know much about material definitions. :neutral_face:

Not sure why it does not fall back to the second Technique if the first one is not supported. Probably I am missing something but anyway try to remove the first Technique (GLSL150) which requires GL_ARB_texture_multisample extension and see if it solves your issue.

Also, please put the stack trace inside code blocks so it would be easy to read.
