Sweet! Great image.

Do you have any tips/workflow on displacement from zbrush to Octane?

Hope you don't mind a crit, but the pours/skin texture looks either a tiny bit big or tiny bit heavy. Rest is awesome.

Cheers.

I'm not sure who this is... Kinda looks like VanDamme, is he him?
You should fix the hair attachment, it needs way more hair and more thin.
Also, he looks sweaty, was that intentional?

Hi prodviz~~

I use Zbrush to blender , and didn't use displacement but I use Vector displacement instead , displacement in lots of application can have good result, but VD can do , and can make your model more the same as in ZB. so maybe you can give it a try , and I don't understand that you mean "pours/skin" , or you talk about pores and skin ?

Hi Rikk the Gaijin~~

you guess right , I really made a JCVD portrait , and about the hair , that is the most hardest part while render in GPU render , heavy and lots GRAM , but I'll try add more hair and make it more thin, and I really want make him looks sweating , just like after do aome exercise.

thanks your reply~~

Cheers for the info.
Using Vector Displacement, do you still need to tweak Octane's 'level of detail' or 'Offset' value?

And sorry, bad spelling, I meant to say 'pores'.

Not if you export Alembic and use Octane built-in hair system. Very light on VRAM.

I just only use blender plugin , so i don't know how to setup in octane render , sorry can't help you

Very nice!

Some people have big pores but just a bit smaller would help i think

Also he looks not really sweaty. He looks like moisturised

Some sweat drips would help to sell the effect and a spec map to make this wet look more uneven.
But since this is a pure portrait and you dont see anything that indicates he is or just was working out I would not give him a sweaty look.
It's kind of irritating.

Other than that pretty well done!

P.S. I just realized that. Could it be that his shoulders are to narrow compared to the head?

P.S.S. .... oh I know im a pain in the ass now but I also saw that the background is showing pure white.
I would leave the brightest tones in the image only on the model so that the background doesnt draw attention to the viewers eye.

haha~~moisturised~~~thanks~~
add some sweat drips might be good idea , I'll give it a try. about the shoulder might be the camera focal length distort or might be really too narrow ,
I'll check that , and about the background too bright that should be true,I'll tweak it~~

thanks for all suggestions~~
