How to enable GLSL extensions like `OES_standard_derivatives`?

See original GitHub issue

Feature

How to enable GLSL extensions like OES_standard_derivatives?

library version

├── gl-react@3.15.0
└── gl-react-dom@3.15.0

Expected behavior

I tried using the onContextCreate function of the gl-react-dom Surface which exposes the gl instance to enable the extension via gl.getExtension('OES_standard_derivatives')

Actual behavior

Assigning a custom function to onContextCreate actually silently prevents any rendering from happening!

Is there another way to enable additional WebGL extensions?

Thx

Thanks @brysonandrew, good to know that works. In the end I found a way to do what I needed without the derivatives extension, but good to know for the future 👍

@efirdc You’re welcome, yes, componentDidMount.

Here is a gist of the whole component

Do you have something like this is your shader -

#ifdef GL_OES_standard_derivatives
  #extension GL_OES_standard_derivatives : enable
#endif
