Light leaks when rendering to texture

[YoyoBoy]

I have a scene that renders just fine, even at high resolutions, but when I'm get leaks in nearly every corner when I render to texture.

Can anyone recommend some good settings to make it stop? Would it help if I broke the model into smaller chunks?

Thanks!

Can you show an image? Generally, if you are baking an interior, make sure the walls have some actual thickness.

Best regards,

I can't post any images, but I do not have thickness on the walls, so I'll try that.

Ok, that partly solved the problem. I found that a lot of the problems were happening where an object with a standard material was up against an object with a VRay material. And this also happened within a single object with a Multi/Sub-Object material.

Assigning VRay materials to everything fixed it.
