DR vs workstation

[grasshopper]

Hi All,

How come when I render using DR I am able to use my workstation almost as normal allowinging the render to complete in the background. But if I do the same render with DR off my workstation becomes usable? I always assumed that both methods utilised all cores. IS this common to everyone else?

Cheers

I did not quite understand - is the problem during the normal render, or during DR?

Create a text file, "priority.ms" and put it in the scripts/startup folder wherever 3ds Max install created it. Inside this file, type the following:

(
sysinfo.MaxPriority = #low
)

Restart 3ds Max, and you can verify it is working by opening the task manager and see what the 3ds Max priority is set to.

@Vlado: The issue is when doing a normal render. When I DR a render I can launch a second instance and happily work in another scene.


When rendering with DR is Max automatically set to low priority?

@Glass-Canvas:Thanks for the info. I'll give that a go. Will it effect the speed of the render? (If I am not working on something else e.g rendering over night)

Yes, when doing a DR render, V-Ray creates the rendering threads with lower priority.

Thanks Vlado that explains it.

Although in the task manager is still appears set to normal.

It changes the thread priority, not the whole process priority. The regular Task Manager does not show thing (but Process Explorer does).

For the normal render, you could try the "Low thread priority" option in the System settings for V-Ray.
