white lines / light leaks

alexworx

Hi all,

I am wondering if anyone can shed some light ( no pun intended ) on why I am getting these strange white lines in my scene.  The enclosed images show a pretty high bake with what I am talking about. The mesh density is pretty high so I know its not that. There are no overlapping UV's so its not that. I am little stuck on why its happening.

As always thank you for your help

Isn't this the same thing as this one of your previous threads?

Yes and No. What worked on the last post is not working now. I am just trying to figure out what I did different and what to look for.

Is the floor a one sided plane , or does it have some thickness? If it doesn't have, have you tried it with a mesh that has thickness? You could just slap a box there for testing, rebake, and see if the error is gone. If it is, just add some thickness to the floor mesh.

I think your on to something but its not the floor because its not happening to everything. I just looked at the far wall with the squares on it. That had no bottom plane on it. But the kitchen cabinets do have a plane on the bottom of it? I wondering if the floor placement is the reason. Taking a closer look I noticed that the floor intersects the cabinets?

I am going to run a bake and see what happens.

Thanks!

Put a new floor mesh from UE4 in and it went away. I guess it was my floor mesh.

Thanks for the help

So it means you need thickness.
