Light Portals - Accelerate Interior Rendering

Post by Mario Tran Phuc » Tue Apr 04, 2017 7:42 pm

Here a basic Light Portal Setup to speed up your interior renderings based on this tutorial: https://www.blenderguru.com/tutorials/u ... der-times/

Left without Lightportal - Right with Lightportal
Both with 32 samples
Rendertime Left : 32 sec , Rendertime Right : 34 sec

The light portal version took only 2 seconds longer but with a much better result.

Here an example file using the build in sky node. You could use your own HDRI Environment instead. Just place the lighportals where the light should shine through.
