Hello,
I have a strange issue when using Ambient occlusion (set to Raytracing and Constant QMC). (I’m also rendering to a texture) What happens is that most of the objects in my scene Bake nicely, but three objects turn out very dark. Does anyone have experience with this issue?
The first thing I’d try would be to remove doubles (W / remove doubles) and recalculate normals (Ctrl+N)
Hi, that did not do the trick. (In case it’s necessary to know, I’m using 2.49)
(I just realized, the lit circle on the right of the image could be confused as the backside of the object, it’s not, it’s a different object.)
My guess is you have a hidden object on the same layer. Even though it’s hidden, it still gets accounted for in the bake. What I do is temporarily move it to a layer of it’s own, do the bake, then move it back.
Hi, I am able to do this, but I need to bake with other objects in the scene. I have tried ALT+H to show everything, and no object is hidden though.
Have you checked the UV? It’s possible that in the UV unwrap faces are overlapping. When faces share UV coordinates all but one will be overwritten with baking.
… and if that’s not it, you may need to post a blend, otherwise we are just guessing. I’m sure we could find exactly what is wrong in much less time.
check normal
check doubles no criss crossing edges
at last use the edges split modifier
happy 2.5
Hiya,
I found if I reset the scale and flipped the normals, everything was okay.
