Hi,
I'm experimenting with fragment shaders and would like to ask if there is a workaround for inputting statements like "#extension GL_OES_standard_derivatives : enable" in the playground, which results in a syntax error? In CYOS such statements are accepted, so it's not a big topic for primary shader tests.
BTW, I'm a new user and I enjoy this forum, it helped me a lot for the first steps learning babylonjs, thanks to all of you for the great effort for this amazing project!
My first shader results: http://www.babylonjs-playground.com/#26UUE1#19
have fun
