lightmap issues #3

Closed illwieckz closed 4 years ago

illwieckz commented 6 years ago

This happens with high quality lightmap, may be a q3map2/engine issue:

Those weird effects usually happen on part of lightmaps that are not expected to be seen (hidden by an opaque brush) but in this case it must not happens.

It must looks like that (low quality lightmap):

Even with low quality lightmaps it can happen, but in different places:

I noticed that everytime I see that artifact (on this map or on others) it's on a detail brush, and there is some translucency next to it.

The bug looks to be in the specular map or its rendering, there is no visible bug when r_normalMapping is set to 0, which also disables specularity.

illwieckz commented 4 years ago

This bug is not related to specular maps. We now have an r_normalMapping option to disable it and disable it does not workaround the bug.

But disabling r_deluxeMapping workaround the bug. It then looks to be related to the normal/deluxe light computation.

Also, this behaves like an overflow.

Closing the issue on this side as it looks to be an engine issue and unrelated to the map.
