Anybody written a Plugin that adds Material Nodes?

You could first make a material that ourputs your scatter values incremented by the UV-Y value or something to make a texture inside of the editor.

basically you just make your scatter function, then at each point you use the Y value of your UV to solve (and bias-scale if you need to capture over -1 to 1 etc). then using the render to texture blueprint or just by taking a screenshot you can get your image.

Does making an exr screenshot save your shader values into the texture to half float 16-bit nicely? how would that work across vendors?

Also I haven’t used the renderToTexture node yet but what if you want precise values to be stores per pixel? Does filtering mess with that or can you specify no AA/filtering etc to get pixel perfect textures. One thing I want to do is store precomputed blackbody temperature in U and white balance offsets in V.
