Do alpha blending shaders exist in IBL? I don't seem to see them in the material editor. Could it be a hidden feature that needs to be typed in json? And I DON'T mean the confusingly named "standard blend" shader, which just blends 2 textures inside an opaque shader. I am trying to use it for painted lines, with chroma transparency it doesn't look good, it's just floating above tire marks. If no, what is the shader to use instead?
