Unions with Decals Appearing Dark

[dr01d3k4]

The trains in my game are made using CSG for the body shape, and decals for the livery. I opened studio just now to find many of these unions are now quite dark. For some reason, it’s not all of the unions, and I can’t seem to fix the unions that are broken. I’ve tried: adding/removing textures, changing colour, transparency and UsePartColour, and duplicating the union.

Screenshots of the problem:

The bug has affected the union on the left, but not the union on the right. You can see how much darker the left union is when it’s supposed to be the same colours as the right.

Edit:
It appears to only be happening to unions that had UsePartColour = false before loading the place file.

Another instance of the same issue although UsePartColour was set to true before, unsure what’s causing it and what solutions there may be.

Thanks. This was literally a single character fix.

Still occuring in my game as of now. It appears to be making decals more “brown” rather than just “dark”.

Happening in my game too.

The fix is in for the next update that will happen this Tuesday night.
