Why is light not showing up on my mesh?

Having a lighting issue if anyone has any input it would be much appreciated. The image on the left is the back wall before I build lighting on it, where we can see the light from the window (and previously I was getting nice light maps on the wall from the same source.)

However, looking at the image on the right it seems the wall is now ignoring the light coming from the window. Light map res is appropriate and like I said it was working before so not sure whats happening. . .

Hi JustGarry,

Looking at the two images and knowing that the two image on the left is before the lighting has been built and the image on the right is after lighting has been built it would appear that there is a problem with the lightmaps.

I know you said that your light map res was adjusted but there are a couple more things we can check with this as well.

If you could post an image of your second UV channel that is used for lightmapping it would help greatly with diagnosing the issue.

Thanks!

Tim

Here you go this is the light map UV’s.

The strange thing is I moved the wall until it was completely bisecting another piece of geometry, and the light map was created correctly, but won’t build when the wall is on it’s own, close to the other walls :confused:

Hi JustGarry,

Double check the settings on your other meshes, like the adjacent wall in the image and see if light will be baked into that. If so, see if perhaps there is a setting in the details panel that is unchecked/checked that should not be.

Beyond that, would you be willing to attach your mesh to this post or a make one that is giving a similar issue?

Looking at the UV there doesn’t appear to be an issue. At this point, it would be kind of hard to diagnose without a similar mesh causing the same issue.

Thanks!
