Title: Strange spots on the geometry
Post by: art-MIXER on 2013-12-17, 08:04:09

Strange spots on the geometry. Quite incomprehensible nature of these spots. Maybe there is this explanation?

Alpha 5

1. It maybe geometry topology?
2. Or, maybe you have somethnig in the scene, what reflect light in this difficult way.
Material of your walls have reflection or not?

Yes, I have stuff on the walls with a bump. My stuff was done using standard procedural maps and a bitmap texture, perhaps the crown is not entirely correct understands them?

Stuff on the walls looks like this:

That's what the texture found in the settings, do not know how this parameter has been changed, but maybe it could serve as such a reaction?

ok, then this is probably caused by a bug I've already fixed. The next stable release should work fine

tried a lot of things:

Bake procedural textures
Changed for different HDRI environment
HDRI changed on Corona sky
Hidden geometry curtains
Reset Xform geometry walls and smoothing groups
Turn off all the lights except for the environment
Changed the types of glass on the door (it was thought that some caustic curve of the glass in the door)

And nothing helped, this bug has remained on the walls (

until there is no more any thoughts about possible causes, so that the only hope for you)))
and when will the next stable version? )

Yet I found the source of this bug )
They were portals in the windows as soon as I hid them, this strange effect on the walls disappeared, only in this case the room was noticeably darker, but it is fixable by exposure)
