V Ray dont use all CPU Power

[sanny81]

Hello Friends,

I have a scene here with dont use all of my 8 cores (local mashine).
Vray only use 1 core spltted in 8 bukets :-\


It says in Render Progress window ten times....

"Light cache time interval is (0.000000, 0.000000)"


When i render with overide material it works fine.
Thats the reason why i converted all my textures to jpg and very low quality too (small size).

Imagesize from final Rendering is 3000 x 4000
I use IR Map and LC.
IR standard settings and LC with 500 Subdev and .02 size
Cubic camera
DR spawner to two slaves
and IR Map from file.

Sometimes Vray stop after 10% and dont finish rendering.
It is not possible for me to share this scene cause its highly confidential.
Is there someone who know those issue and give me some input to fix it?

THX

Yeah i think i´f got it now !!!

The only problem was my Polycount.... Resize and decrease my 3D Models to lowest Polycout and now it works!

It was a RAM issue!

That makes sense to me - if V-Ray needs to buffer write to the HDD, the process slows way down so that only one core is needed to calculate the rendering. :
