I'm getting this artifacts when rendering. Sorry I cannot post the scene.
Blender version: 2.76b
TheBounty version: 0.1.6.4
Operating system and version: Windows 7
Official build downloaded from https://www.thebountyrenderer.org/downloads (yes).
Subdividing the floor gives similar results.
Don't can appreciate the possible cause of artifacts only see the render image. You can shared the scene, please?
Sorry I can't.
Here is the wireframe:
I'll make more tests.
