What is the best practice (for performance) dealing with skinned mesh using decals (here) or texture update (here)? Decals example seems to be fps greedy way in case of hi-poly skinned mesh due to it consists of whole positions attribute recalculations as well as normal etc ? If I need customize skinned mesh by adding some details such as scars, tatoo, etc… I believe the best approach will be texure update but not decals? In this case what is the main advantage of decals over texture update (from description “adding unique details to models” seems to be disadvantage in this case) ? Only covering seam?
Thanks in advance!
