We will be testing the wall clock time for all renderers. Every renderer will be run 3 times in succession and the average time will be taken. We make sure that nothing is running on the machines so not to slow down the poor renderers. The render is launched from Maya. We have three test machines available:
| Mac | Linux | Windows |

Multi-Light Rendering Performance Test using 3Delight OSL
3Delight has a feature called multi-light . It – it let's you separate lighting components per light or per sets of lights. It is a subset of the LPE feature, in OSL parlance. This extra test was done to see evaluates the performance degradation when using this feature. Setup is easy and can be Multi-light rendering is enabled in the Image Layers section of the OSL render pass. Just ; just select the RGBA layer and select the two area lights.
