To use radio city, you first need to create a scene in 3D Max. The scene should include a model of the object that you want to render, as well as lights and cameras. Once you have created the scene, you can open the Render Setup dialog box (Rendering > Render Setup). In the Render Setup dialog box, you can enable radio city and specify the settings that you want to use.
The following are some of the most important radio city settings:
* Quality: The quality setting determines the number of rays that are cast from each pixel. A higher quality setting will produce more accurate images, but will also take longer to render.
* Max. Depth: The max. depth setting determines the maximum number of times that a ray can bounce off of a surface. A higher max. depth setting will allow for more realistic reflections and refractions, but will also take longer to render.
* Light cache: The light cache is used to store the results of previous light calculations. This can help to speed up rendering by reducing the number of times that the same calculation has to be performed.
* Global illumination: Global illumination simulates the way that light bounces off of surfaces and indirectly illuminates other surfaces. Enabling global illumination can produce more realistic images, but will also take longer to render.
Here are a few tips for using radio city:
* Use a high quality setting for best results.
* Use a low max. depth setting for scenes with simple lighting and materials.
* Use a high max. depth setting for scenes with complex lighting and materials.
* Enable the light cache to speed up rendering.
* Enable global illumination for more realistic images.
Radio city is a powerful tool that can be used to create photorealistic images. By understanding the settings and using the right techniques, you can create stunning renders with radio city in 3D Max.
