I need an object that is working as emission surface lighting my scene and another object that is also emitter but casting shadow only and retain its lighting completely off.
I am working on a project with orthographic render and I need a light that is blending in to dark from a middle of the scene so I have sides of the render dark but center brignt… this is all good but I have no shadow cast visible due to its emitter position.
If I add an emitter that cast shadow to a side only but not the light I should then be able to get shadows and still keep the light blending out from center.
hi agian, do you know why do I have blue shadow instead of black appearing both in viewport as well as render? I have set the power, shape, size and spread of the positive and negative light to exact same value for both and I also placed them in exact same position, then I added third light which is my main light that does not cast shadow.
Hmm, I have tested and get something similar when I give the objects a bit of colour, no idea why, it seems to be something to do with the roughness value and the colour of the objects, with roughness. The tinting changes depending on the object colour the more saturated the colours the worse. (greyscale has no tinting.)
Maybe something to do with shadows darkening reflected colour.
Edit, changing roughness does have an effect but does not always fix altogether. At first I thought that with roughness at 1 or 0 the shadow was black but depending on the colours of the objects they also tint the shadow.
