Directional Lightmap issues have been gone over a few times in the past for issues with specular reflections, but I can’t seem to find any that relate specifically to this.
The attached image shows a simple test scene with a Splotlight and an Point Light, casting a shadow. Specular hilights are incorrectly represented by the lightmap scale texturer in the penumbra of the shadow, and spotlight contribution.
This has nothing to do with multiple light source contributions - the effects are the same with 1 light or a hundred.
Area Lights have no such issues - see the cobbled together spotlight in the bottom image.
Is there a solution to this? Or an explanation as to why it can’t be fixed? Is it because Beast wants Photometric lights? And since I’ve mentioned it, can we expect support for photometric (i.e. IES) lights in a future release?
