As every body knows, making a final render or animation can take a lot of time.
You can optimize the time of render by choosing between the CPU or GPU.
What I do is render in GPU. And then open a new Blender session and start modeling work with CPU. So in the background, Blender one is rendering a scene, using GPU. While I’m working with Blender two on a next project with CPU rendering.
If both Blenders use the same hardware, my PC is very slow. I use this trick also for daily work. On the background Blender one is rendering on GPU time.
awesome tip, i need a better cpu to do this! i believe theirs also a way to render in both ways and combine them some how? maybe thats the animation portion when we did the bouncing lamp
In Blender you mostly render animation clips, frame by frame, like 1, 2, 3, 4, … Or use a configuration where only the n-th frame is rendered, like 1, 6, 11, 16 etc…
So you can configure Blender 1 with CPU doing 1, 3, 5, the odd frames.
And Blender 2 with GPU doning 2, 4, 6, the even frames.
Another solution could be, using a commercial render farm. Or build your own with Raspberry Pi’s
I just watched the video on the multi render … Fantastic … But I wanted to know if I use the CUDA (with cpu n gpu) can it give problems?
If I use both gpu and cpu does it give advantages to use 2 instances or not?
What kind of problems? Blender just works fine in all modes.
Using two blender instances simultaneously, one for rendering a project. The other one to work on a project. Will divide the workload one is using GPU and the other CPU. I see them as two separated hardware devices.
If I render in CPU and work on a model also in CPU, my computer is too slow. So I divede the workload to GPU also.
And at night I start 4 or 5 Blender instances for render. But I must say, sometimes my laptop is becoming unstable due to overheating.
And if I’m informed correctly, Eevee can not use GPU, Cycles can.
In daily work it is obviously a great help to use one instance to render ONLY with the gpu and another to design where you use the cpu.
And this is FANTASTIC!!!
I ask you, if I use both gpu and cpu in Blender’s preferences, do I use both to render whatever I choose as a device in the render properties?
So I should set the Cuda so that I can choose only the gpu or only the cpu as a device … or not?
What if I use 2 instances to render on one machine as seen in the lesson … in this case is it really useful? Is it faster to use 2 separate instances using cpu and gpu separately with the appropriate settings or to use only one with the use of both with CUDA?
