Weird shadow issues

Not sure if this is in the right category, let me know if there is a better category for this post.

So I have a forest full of trees and a day night cycle. When night arrives, Lightning Brightness is tweened to 0, aswell as Ambient and OutdoorAmbient. I’ve noticed that the trees for some reason generate light?

They glow on the bottom as if they are projecting a negative shadow. As if instead of absorbing and reflecting light they intensify it. The tree stump is about 0.1-0.3 studs buried into the ground. There are absolutely no light objects inside the tree model. The ground is Sand, colored (200, 200, 200). The trees are made up of cylinders for the branches and sphere meshes for the leaves. This has not been an issue up until recently.
Please tell me there is a way to fix this because this looks horrible.

I made a new place on roblox with about the same settings as my game.
As you can see, the area under that huge block that is covering the moonlight is somehow better lit than the surrounding environment. the taller the block is, the more intense is the light.


Setting to Realistic didnt help. Changing EnvironmentDiffuseScale and EnvironmentSpecular scale helped.

have you tried toggling cast shadow?

That did solve the weird shadow problem, but now the tree or the block won’t have shadows from the sun.

I’d start by refining these values. You can test the effect by setting them and adjusting ClockTime manually in the editor to quickly preview the outcome.

i mean i’d just toggle the property on the parts based on the time of day, like once its turning day just turn it back on

I’ve settled to turn EnvironmentDiffuseScale and EnvironmentSpecularScale to 0. It seems to fix the problem just fine. Very weird behaviour though.
