1. Here's how
Render speed will decrease if your Project is 'too complex' and if your hardware is not powerful enough and/or lacks available System Memory and Virtual Memory.
The symptoms of a 'too complex' Project are that the screen turns white and your PC becomes unresponsive while rendering.
1.1: To reduce the time it takes to render a Photo or a Clip, you should try to reduce the number of each of the following elements in your Project.
| A: The number of different models you have added to the Project. |
| B: The 3D Points number in the top right corner of Build Mode. Click here to see how to reduce this number. |
| C: The number and resolution of textures/materials. |
| D: The Movie/Photo Effects you are using, in particular, the Sky Light and Hyperlight effects. |
| E: The number of Reflection Planes you have added to the Reflection Effect. |
| F: Sky Light in Planar Reflections in the Sky Light Effect is turned on and you are using Reflection Planes in the Reflection Effect. |
| G: The number of Spotlights that are set to Shadows: Dynamic in the Project. |
| H: The number of Spotlights you have selected in the Global Illumination Effect. |
| I: The number of large surfaces you have assigned 3D Grass Materials to. Click here to see how to optimize them. |
| J: The number of Video Textures you have assigned to materials. |
1.2: Please also note that you can also shorten render times by reducing the Output quality, the Frames per second and the Output resolution.
- Example: Rendering a Clip at 1280x720 pixels in 3-star quality and 25 frames per second is a lot faster than rendering the Clip at 3840x2160 pixels in 5-star quality and 60 frames per second.
