Just when I think I know everything there is to know about RPCs, I learn something new. My latest nugget of knowledge came from long time user Steve Phong, of Overland Partners in San Antonio Texas. Steve taught me a super easy way to change the opacity of RPCs using Mental Ray. I had always thought that the only way to do this was via the material editor or via scripts available for the Scanline renderer.
To change opacity in Mental Ray:
1) Right click on an RPC and select Object Properties.
2) Change Visibility to a value between 0 and 1. A value of one is completely opaque. A value of 0 is completely transparent.
Thanks to Steve for this excellent tip. If you you have a tip or trick to share, please e-mail me at support@archvision.com.
