I know both of these are being worked on, but I just noticed that GI wasn't applied to the fake stones.

The fake stones in this file are heavily displaced and have TG surfaces for texturing. There are 3 fake stones layers, small to big from bottom to top. Adjusting the levels in Photoshop shows the shadows to be a solid colour. Stone sizes up to 1.5, GI detail 1, quality 4. Render time was also shorter than expected.
This is something we're aware of. Thanks for the report. :)
