Hi, I followed this tutorial for an awesome looking low-poly water for a simple looking Android 3D game.
Unfortunately the code needs GLES3 partial derivative functions like dFdX() and dFdy(), which crashes when deployed on my Oneplu5 (Android 7.1.1).
Only GLES2 runs on my device, which means, no access to partial derivatives...
It seems OpenGL2 can run extensions including the one containing dFdx() and dFdy().
I see people using this define to enable the extension
#define GL_OES_standard_derivatives 1
Is there any way to either
I have a lot of C++ experience but not in OpenGL and not in Godot shading
