Let me know your Discord name tag and i'll add you as a friend on there.
I can show you my custom tree textures as well as how to alter the treeBranchShader coding to stop GIANTS crazy over the top saturation.
The issue is they have autumn tree leaf colour set to change by nearly full saturation. On in otherwords it takes the autumn colour on the diffuse and moves the saturation to nearly 255 on the RGB scale.
Whoever came up with that at GIANTS is the biggest numpty ever and does not deserve to be paid as a professional dev.
