Slow render - High CPU

Post by Wiggs7 »

Hi all,

Wondering if I am missingh something.

V 7/0/3 on windows
3D view/create a photo/

Even if I choose 3 quality, it's taking a very long time.

I also note that CPU usage is high (99%), but GPU low (10%). I have a decent 2080 GPU and was hoping to use that to assist the render?

SH3D doesn't use GPU, only CPU.

If rendering takes too long, there are many options to reduce rendering time. Search the forum or try one of these:
- reduce number of lights
- choose smaller models
- make models invisible that do not appear in the image
- etc

Thank you, all.

SH3D must determine for every object where it is and whether or not it is visible in the image that will be produced. This takes time.

If you remove all objects that will not appear in your image, the render engine doesn't need to do these preparatory steps.

So... make invisible all levels that don't appear in your image and do the same for all objects.
