Render raytracing problems

Post by grimey » Mon Nov 21, 2005 4:47 pm

I'm seeing some issues with blender raytracing. Basically, raytracing seems to cause faces not to be rendered. I might even be doing something wrong :?

Might not be that, but try to recalculate normals outside.
How to use a Blender:
Put your model, rig, animation and textures in the Blender, turn the Blender on and wait for it to Render, then turn the Blender off and show it to your friends.

If you use a CVS build... I think thi's a bug.

Negative on recalculate outside, same problem.

Um, CVS build...? I'm using 2.40 alpha 2 installed on win XP pro, so I think so!

I take it then, that this is already reported?

This perhaps a bug in the raytraced shadows.
Unified render don't fix it for me, but disabling shadows yes.

No bug, just overlapping faces. The coil is build from several parts, which overlap eachother at the endpoints.

Overlap or not, wouldn't that be a bug?
