Hi allI notice on my scene that sometimes .. not always .. when I render the nods render without using all core , this is very strange and is not happening all the time, is any way to set the core ?Thanks
I think what you may be experiencing is something particular to blender's render engine. We use the cycles or blender internal engine in the background to render on your computers. So if you have set threads to automatic in the performance tab, then the render that will be done should be equivalent to using blender its self to render in background with those same settings.
It would be great if you could try something and let us know. Would you be able to test the same scene using blender alone and see if it has the same issue with your CPU cores not being pushed to 100%?
