Title: Is still the problem of the sun
Post by: woshilvba on 2012-10-26, 17:12:29

In one scene, I use the sofa. The sofa material contains reflections and bump. When the sun on the sofa, the sofa will appear irregular point.
I would like to ask how can I reduce the irregular point?

Maybe you should show material settings?

This is because specular surfaces are VERY sensitive to bump. The sun gets reflected at multiple positions, due to varying normals. This is correct - it should happen, but it's probably not what you want. Best solution would be to disable the reflection visibility of the sun, but that is not implemented yet. You'll have to work around the problem. It should be implemented in next alpha

Will use the next version of delta computation in the reflected or refracted?

I'm sorry, I don't understand that...
