Godot Version
4.3
Question
Hi,
When I export a tree from blender as fbx, then it looks like this after inporting in Godot. The colors not match what I import so have to change that:
Where are the weird colors came from?
Then when I export to glb the colors are fine after import in Godot:
But… when inserting in in a scene and play the color of the bark is suddenly white:
I can change the albedo color a little so it is more brown but am curious why it changes, someone know?
Also am curious why the fbx is green with purple colors after import, someone know?
And Fbx is smaller in size but guess glb is better?
Would have to know about your export settings to solve the strangely colored fbx, guessing you are using vertex colors as data though.
Does your environment have a non-white ambient color?

Where do you get the tree from? Maybe this tutorial can help you?
Create trees with wind effect
True, it is not white so that could be the issue, thanks for noticing that 
I use treeit just as your tutorial only the shader is different then in the example, I go t read it and use it also, thanks
The color issues with FBX may stem from how vertex colors are handled. Exporting as GLB is generally better for preserving materials and textures.
