Attached is a preliminary render of my current project. After finally having
found an appropriate sky and light set up I'm now struggling with some ugly
triangle shadows on the foreground rock (bottom right side). Does anyone
have an idea how to get rid of them?
The rock is a smooth triangle mesh but it doesn't look like this in some
places. The scene has one light source, media sky, uses radiosity and is
rendered with Megapov 0.7. I tried double_illumination with the rock mesh,
but it doesn't have any effect here. May be an area light for the sun would
help, but that would make the render too slow even for 2 GHz PC. What else
should I try ?
By the way the cylinders are just dummies. They will be replaced with trees
if I can fix the triangle shadow problem ...
Regards and thanks for any hint ...

See section 9.8.1 of the POV-Ray docs.
I'm currently working on a patch that works around this, but it probably
won't help your particular case 100%, because of an issue I plan to work on
solving next.
Basic solution: See if you can make it have no_shadow without affecting the
rest of the scene.

try a fill light
I suspect many of the triangles are due to the rock structure - use an
Isosurface rock instead?

Thanks a lot! The no_shadow keyword works perfectly here because the shadow
of the rock is not visible in this scene. I will also try the isosurface
suggestion over the weekend ...
