I’ve been trying to render things with the blenderseed renderer in Blender and it’s not quite working as I expected, and the lack of easy to understand documentation does not help. When I had just only area light (figured out these work the best, but correct me, if I’m wrong) all renders without problem, as shown here:
HOWEVER. If I add one or two more lights to the mix, small dots of light start to appear:
It does not matter which light is enabled, as long as it’s the only one enabled. If I enable only the light which caused me an issue in the previous render (in this example the rectangular light to the right), it renders without the dots. What am I missing? By the way, this was rendered with caustics on, SPPM lightning engine selected and 4 samples, 500 passes. I’ll be glad for any help on this, google and youtube are not giving any answers.
Edit: The only solution I’ve found for this is to render the light sources separately and then compositing them in photoshop, but that’s hardly a solution.
