easy rendering for Rhino in Windows
Block issue
I've noticed an issue where Blocks do not render properly. The block has weird shadows. These go away when it is exploded into a polysurface. I let both versions of the render run for 16 passes.

Can you send me the model? This is very interesting, I cannot get it to happen here, but I have some ideas of what it might be.
Are you running Rhino 4 or Rhino 5?
You can post it here, or email it to scottd@mcneel.com

The Beta build 28 should have this problem fixed.

Blocks that had a negative transformation matrix. That would be blocks that are mirrored in specific ways would get completely reversed normals on the render mesh. This essentially turned the render meshes inside out.

I see the problem and will talk to John about it.
The problem seems to be from Blocks which are mirrored. This will creates a negative transformation. You can copy and rotate these blocks into place and will get good results. I know this is a workaround and not a final solution.
