Reflectance is more saturated on Meshes and Unions compared to normal parts

[Panwellz]

I have 3 parts, 1 MeshPart, 1 standard part, and 1 Union. They all have the same color and same reflectance, yet the union and meshpart looks much brighter than the normal part in the middle:

This happens with all colors, and it gets even more noticable with higher reflectance. Here are the parts i used in the screenshot: Reflectance Example.rbxmx (8.5 KB)

I have a gtx 1070 with the latest drivers on the computer i took the screenshot on, but it appears on my laptop with integrated graphics as well so that’s probably not the problem.

This started happening a few months ago, i’d say more than a month ago but less than 3 months ago. But i can’t tell more accurately than that.

There are currently a lot of visual differences between normal parts and MeshParts or Unions, which is very noticeable on some graphics levels.

Perhaps this is related to:

Normal and Bump maps not showing on MeshParts

When materials are used on MeshParts, the bump and normal maps do not appear. Foil appears flat and Plastic appears flat, even though the diffuse and specular maps appear fine. [image] The mesh that is shown was uploaded pre-materials update.

Same here.
I was putting Unions into an older map that had only Parts and noticed this and it looks pretty odd in gameplay when the Parts/Unions shouldn’t appear different but do.

I reported this as an issue.

Thankful!
