I added a dithertemporalAA on the opacity because it doesnt look like hair without it

This is without dithertemporalAA

I’ve been tinkering on the hair materials and I can’t seem to remove the bluriness on the hair. Changing TemporalAA to FXAA/SMAA on the project settings introduces alot of aliasing which destroy the strands.

Will the stylized Hair Shader in the Marketplace solve this?

Edit:

Also the motion blur. Even though it was set to 0 and no postprocess in the scene. It will still blurred the movement.
