How to get the best scene performance

In-depth guide to increase the 3D rendering performance.

Do you want to render fast? Real-time rendering is a valuable solution when it comes to delivering your projects in time. But the possibility to render even faster won’t just save you time. It also helps you to be more competitive and stay creative.

12 tips for a faster performance

In this article, we collected 12 easy tips that will improve the performance of your scenes. You can get more details about each tip, by watching the quick tip at the end of this page.

  1. Lower Polygon Count: There are a lot of ways to get rid of too many polygons of an object, but one great way is to use the Remesher of Cinema 4D that in some cases will help to make the viewport a lot quicker.
  2. Decrease Live-View Scale: If you go to Live View, in the U-Render Settings Dashboard, you can enter a lower percentage value on the scale to make the  viewport way quicker than before. 
  3. Decrease Blurriness Parameter: In some cases it also helps a lot to decrease the blurriness percentage.
  4. Multi-frame Sampling: By activating Multi-Frame sampling, the viewport can get a bit slow. So you can decrease the amount of samples, or you can deactivate the Multi-Frame samples at all, just for editing. You will notice that the viewport is way more performant. Turn it back on for the final rendering.
  5. Lower Volumetrics Resolution: The Volumetrics resolution is also something that can be decreased for more performance. In the video you will even find another small tip for you.
  6. Change Shadow Resolution: The general shadow resolution is important for the performance as well. A lower resolution while working on the scene, can help to increase the performance.
  7. Use IBL instead of standard Lights: Image-based Light can also help to have a better performance. Watch the video below to discover how.
  8. Use Spot-Lights: Did you know? Spotlights are much more performant than normal Omni lights.
  9. Lower Near Clip – Far Clip: It can also help to lower the near clip and far clip settings in the light tab. And again, of course, in the scene, if you’ve got a high resolution shadow map, you can lower this one to get even more performance.
  10. Lower Object Count: When you are finished working on your scene, you sometimes end up with a lot of objects that are actually not needed. Cleaning up and decreasing the amount of objects will make the viewport faster. 
  11. Create a Render Setting Child: While editing a scene, it will help a lot to create a second render setting, where you deactivate some features for a quicker viewport.
  12. Lower Displacement Level: Go to the settings and change the subdivision level to increase the speed of your viewport.
