I copied/pasted the Trunk and Branches materials from Bulky to ConeShaped Conifer plant.
I increased the TAA boost to +4 for leaves1, leaves2, trunk and branches materials.
I enabled the TAA parameters as "Ultra" settings in the Rendering Options.
But the result is the same! Nothing changes.

I think that the problem is not over trunk and branches materials (procedural barks).

I have seen  with 3dsMax RAM Player viewer, the previous/after renderings:
The problem seems to be over the too crisp leaves, not over the barks.
Also with TextureFiltering 100%, the smooth is not enough over ConeShapedConifer leaves and they flickering...
Any suggestion?
