currently im reworking our 3D Trees to fit to the new LOD requirements. In this context i want to decrease the "shine" at my alpha textures for the branches and leaf. as you can see at the screenshot, whenever the sun hits the faces applied with the alphha material from behind , i notice some strange shine at those faces.
the roghness channel is pure white, the metallness pitch black, from this side there should be no shine applied by the PBR material. Are there some settings for the material to avoid the shining alpha textures?
