Shader tools

[Thyandyr]

I saw some references to node based shader designers, but could not find any proper ones with quick looks. Anyone know any?

Also a simple syntax validator would also/alternatively be beneficial. Like I wish there was an easy way to just write

sqrt(a*b)

and the edit would tell you if there is a sqrt in the version GLxx being definied instead of trying to find out from manual/compiling the shader. Anyone know such things?

Other than Sublime text. I love it and I hate it too. Syntax highlighting, OK. Build environment setup is more of a mess. I got it working to compile Skyrim Papyrus (through MO) and I'm too scared to touch it now. I don't even know what is ANGLE. (https://github.com/WebGLTools/GL-Shader-Validator)
