Hello, I’m trying to figure out how to get rid of these white highlights that
appear on my tree canopies. This happens as the distance between the tree and
the camera is increased. I have tried every material setting I can think of in
Blender, including adding a COMP ( R : White, G : White, B :
Black) and removing the normal texture. I even compared the model with some 3D
pine tree models I have that work without issue, and mimicked the material
settings based upon that. Here are my current material settings:
Because I know it will come up,
I have also tried it with
Alpha Mode set to
Masked ,
No Cast Shadow
enabled , BSDF (Shader) instead of Principled BSDF (BSDF is default, and
what I normally use),
Backface Culling enabled with leaf geometry
duplicated and
normals inverted (So backfaces could have proper shading).
flat shading vs. smooth shading, and probably a couple dozen other settings
combinations. I feel like I have exhausted everything, but maybe there is
something dumb that I’m missing… Any ideas?
Hello @Rotornut44 Can you check you do not have the issue described here?

Hello, That was the first thread I went to, and I have tried all of the
recommendations made there. The issue appears to be different. From what I can
tell, it seems to be something with lighting still reflecting off the tops of
the leaves, then because of the number of polys, it just looks worse at a
distance, as the model decimates and the lighting shader begins to change. To
me, it just looks like specular highlighting, but there doesn’t seem to be a
way to null it out.
Hello @Rotornut44 I think the problem comes from your albedo maps. You’re
using a light color background where the alpha is set to 0 but when
downsampling those maps, this light color is bleeding on your leaves. You want
to use some sort of edge padding to avoid that like in the picture below:
Try that and let us know if that
solves your issue. @Nocturne Probably something we should mention in the doc.

Hello, I have generated padding for the leaf texture sheets and verified that
the textures compiled correctly (Solid background, with padding and an alpha
channel). However, I’m still running into the same problem. I will attach the
updated DDS files in a private comment.
