Suggestion: ZBrush testing

[MadJ]

Hello Linus Tech Tips,

 

you guys might ask yourself for what those threadripper cpus are. Who are those 3D-People that use it. Frankly it is not so often 3D-Rendering but 

a Programm called Zbrush. It is used for 20 years now for making all sorts of 3D-assets. Because the programm already exists for such a long time it does

not use the gpu (just for bevel pro) and needs a multicore cpu, a fast ssd and lots of fast ram. With 128gb you are fine, 64gb can get tricky but often does also the job.
A better PC (except gpu) will literally cut work time, allows for higher detailed Assets/ easier workflows and increase the quality of life for the artist.
If your machine can't handle the workload you have to split a character for example in 3-4 parts to detail it.

If you have an high res model that has... idk like 200 million polys (probably someone will donate a model for you), you can test it like this:
- decimation master pre process: This analyses the mesh before you can reduce the poly count. It is pretty much like blender scene rendering, the less second it takes the better.
- zremesher (same, adapt off):  It will analyse the mesh and give you even quads. Again, less seconds the better.

- project all:  Rays from the first mesh get send out to hit the detailed mesh. Less seconds are better.
- rotation the model utilises all the cores.  Even a 7950x still is not enough, that is why people buy threadrippers.

- sculpting on the mesh: Single core performance. When does it lag?

I mean most of the stuff you mention here is basically on a case by case basis because if you even work slightly optimized this:

Doesnt happen

Sorry, but whats the point here? Are you asking them to do something so you could benefit? Or just thinking up something that can utilize more cores?

Since all performance test are synthetic  cinebech, geekbench, etc.   and the real performance test are exclusive to blender render, video export and game fps, I wanted to suggest another test that show statistics for  "3d professionals" linus is often referring to.
