Rendering with mental ray: Tips and TricksBelow are the steps for creating this beauty pass:1. Create a Daylight SystemWhen you first click on Daylight it will ask tochange your Exposure settings under yourEnvironment dialogue. Choose Yes. Simply clickand drag to set the scale of the compass. Whenyou release your mouse it will ask to create a mrSky map in the Environment Map slot. ChooseYes. Now when you move your mouse it will movethe height of your Sun. The location is irrelevant,and just a visual indicator.2. Adjust ExposureOpen your Environment dialog by goingto Rendering->Environment or hitting “8”on your keyboard. Adjust your EV(Exposure Value) to 9. The standard forinterior daylight is 10, but I prefer 9 togive it a little more light6

In all scenariosthis will shoot all of the calculatedrays back to the camera, makingthe render brighter. Sometimesthis does create some artefacts.If so, you can switch back toStandard.Also Turn on GI (Final Gather).Typically the default values workfor most scenes. If not, checkMaximum Sampling Radius, andspecify a size that’s very large like30’. When off, the default samplesize is 1/10 th of the scene size.4. Place your LightsOften it’s not the light fixtures in 3D that light your scene butrather the Indirect Illumination. Now that your overall lighting iswhere you want it, we can add lights to show interior lightfixtures your scene. These do cast shadows and make yourscene brighter, but are more for the visuals of the render thananything else.7
