I want to create a material that has transparency and by default is completely transparent.
However, I want shadows to appear on the material which have transparency based on their intensity (so a full black shadow would have 0% transparency and a mild shadow might have 50% transparency).
The effect I am after is what shadows would look like if being cast on to invisible objects.
Is there a shadow colour/intensity variable i can use in a pixel shader? I’m new to ue4 shaders.
