Taking too much time to render. Can someone help please?
Taking too much time to render. Can someone help please?
PC Specs
Window 11 Pro
Graphic Geforce RTX Nvidia 3080
i7 12300
32gb ram
1tb ssd
1tb hdr

Only 4% of GPU is in use and 25% of CPU (how to increase it consumption so as to make the rendering much faster?)

Paid version of Sweet Home 3d from Microsoft Store
All plugin install

Re: Taking too much time to render. Can someone help please?
The current renderers (SunFlow & YafaRay) use the CPU for rendering, not the GPU so it's no surpise that the GPU load is low.
What you can try is to increase the amount of memory Sweet Home 3D is allowed to use. This might avoid some swapping and should increase the overall speed.
How-to is described here: http://www.sweethome3d.com/faq.jsp#increaseMaxMemory

The time needed to render mainly depends on the complexity of what you render. A tree takes a lot longer than a simple box. Textures take more time than colors. If you can simplify the scene you want to render this should help more than anything else you can do.

Re: Taking too much time to render. Can someone help please?
General tips to reduce render times:
- use small models (in Kb) with low poly count (e.g. avoid trees/plants)
- use few light sources
- avoid mirrored and/or transparent surfaces/objects
- make invisible what is not in the image (models/levels)
- use no or small textures (512x512 pixels is generally enough)
