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?
I would like to know the answer to this as well. I can use 3D Studio Max to expert a mesh using the gMotor plugin to make the transparency but not the IBL shaders using the MaterialEditor. The only way I got it to work was set Src Alpha and Inv Src Alpha in the blend settings is that the prefered way or is there another way to do it?
