Description
We use a tree model with alpha masked texture in gltf form that has a strange blending artifact when viewing many trees behind eachother and OIT enabled. The artifact is not present with OIT disabled, but then rendering is incorrect, as expected.
**OIT enabled**

**OIT disabled**

Contributor guide
Research direction
The report concerns additive-blending artifacts in Order Independent Transparency when rendering many trees with alpha-masked glTF textures. No file, test, or entry point is named; first reproduce the scene with OIT enabled and disabled, then trace the OIT blending path. Done means the artifact is removed while transparent tree rendering remains correct.
