[BUG] TMFX breaks/cancels all light underneath overlapping overhead tiles

[baileywick]

Module Version:
v0.6.1.2

Before open any issue
console errors attached. console-errors-1665100226981.log

Describe the bug
Whenever there are two overhead tiles in a scene, and those tiles are overlapping in any way, all lighting under or above the overlap is rendered inert. This only happens when TMFX is enabled and active in the world. No other modules active.

To Reproduce

1. create two overhead tiles in a scene. Overlap them any way you like.
2. put a light under or near the overlapping area of the tiles
3. place a token under the overlapping area of the tiles
4. you will see that the light does not render around the token

Expected behavior
Expecting to see lights shine properly in a scene with overlapping overhead tiles.

Thanks for the report. I will investigate it and try to fix it for the next release.

Interestingly, I opened another session and couldn't replicate the problem. I'm afraid something else is a factor here, too.

Your error logs indicate you had tiles that were <= 0 width and height? Might be something there.

Do you still have those errors in the console with it now working?

I'm afraid this bug is back. And I can reproduce it reliably.

PROBLEM:
If there are two overhead tiles that have TMFX filters applied to them, the overlapping area does not allow light to shine. This is specifically when using the following modules:

• TMFX
• Levels / Better Roofs / Wall Height
• Libwrapper

Ripper thinks it's a problem with TMFX.

No console errors.

Scene export is attached, if it helps.

These are two sample scenes (.json changed to .txt so they would upload). You'll see that scene only has a single TMFX tile, and it still blocks light.

This problem is related to core. I know how to solve it.
