Hey all,

I am currently trying to develop some replacement shaders for Paraview, I know that there is a replacement shaders tab but I am trying to understand that when replacing shaders, how to find the original shader to replace.

Continuing, when replacing a shader it replaced all the existing code for the shader (at least I think), is there a way that when replacing a shader it replaces only that specific line instead or replacing everything?

Any other information regarding shaders and Paraview would be greatly helpful.
