Raytracing Overrides

Video captions: Open Render Settings and select the Raytracing Quality tab. Select Precomputed Illumination as the Interactive and Stillframe modes. Activate Raytracing in the toolbar. Open the Material Editor. Select the tire geometry in the render window, in order to see the material properties. Open the raytracing section. Activate the function, Override Illumination Mode, select Precomputed + IBL for both the interactive and stillframe modes. Now your scene will be calculated in Precomputed Illumination and the tire material in Precomputed + IBL. This means that glossy reflections and correct shadowing will be visible on the tire. Select Shadow Material. Open the Raytracing section. Activate the function, Override Illumination Mode, select Precomputed + Shadows for both the interactive and stillframe modes. Now, shadows will always be calculated in the Precomputed + Shadows mode. Activate the function, Override Shadow Sampling Quality and select setting 2 for interactive and stillframe quality. Now, shadows will be calculated in higher quality. Play around with the several render modes and settings to achieve the optimal quality and performance for you.
