Hello every one!
I try to make sail material with good translucent effect. But when i apply shader , translucent return bad grided effect.
I try use classic shader core refractions with GGX and translucency. All give bad view. (

First of all - PC spec: Threadripper 2990wx, 128 Gb memory, GTX titan X. All devices not overclocked. Only stock.
Problem - mantra render work slower when all 32cores (64 threads) is active. But! When active only 16 cores (32 thread) mantra render work faster. 32 cores - 2.54 min, 16 cores 2.11 min. At same time Arnold render, in Maya 2018 update 4, work more predictably. More cores - more speed. 32 cores 1.26 min, 16 cores 2.17 min. Screenshot and test scenes in attach.
UPD. Interesting situation with SMT (simultaneous multithreading) technology. When SMT off with 32 active cores, mantra work much faster - 1.53 min vs 2.54 (SMT on).
When active 16 cores and SMT off - 2.30 min. vs 2.11 min. (SMT on).
Bottom line.
Mantra - 16 core, SMT on - 2.11 min.
Mantra - 16 core, SMT off - 2.30 min.
Mantra - 32 core, SMT on - 2.54 min.
Mantra - 32 core, SMT off - 1.53 min.
And after some tweaks in bios (not direct CPU overclocking)
Mantra - 32 core, SMT on - 2.19 min.
Mantra - 32 core, SMT off - 1.35 min.

Has anyone work with shop_oglpath? i'm trying to make simple material for visualization textures. The easiest way is make shop_materialpath link to material with ogl properties, but its not interesting.. The idea is use simple shader only for viewport, in help we have this
shop_oglpath string The path to an OpenGL shader to use to shade the surface in the viewport.
but when i set path to my material in shop_oglpath nothing changes. If i use shop_materialpath for same operation - it works. Can anyone explane why? And how to make shop_oglpath work? Th
