Light Leaks

Hello friends

Check out this wonky light leak I'm gettin:





Strange, aye? Oh, and my lightmapper's resolutions are 2, and my parameters are Default-LowResolution.
I have a big open world, so having high quality lighting isn't really gunna work, from my experience.

Any thoughts? It ain't pretty ^_^

You must increase lightmap resolution or lightmap scale for your important models

This problem is only related to lightmap resolution

 

Alright, turns out the issue is a bit more complicated.

When I have the house in a modular form (many meshes) the light doesn't leak.

However, when I merge the house into a single mesh, the light leaks happen!

*thinking emoji*

 

Each model has its own UV space (lightmap UV)

For Example :
1 mesh with 1000 poly = 10 unit uv space for each poly
10 mesh with 1000 poly = 100 unit uv space for each poly

In this case (combined model) you can use higher lightmap size (2k or 4K)

 

This was my guess! How do I change lightmap size?

I tried switching the lightmap resolution in it's lightmap parameters, and it just makes the gaps higher resolution:

EDIT: Alright, I changed the resolution for the object to be 3, and most of the leaks are gone. This seems like a really high resolution, but I guess it makes sense since the combined object has 26k verts!

Thank you friend
