User is using keyin : RENDER VIEW (Ray Trace, Phong or whatever) and it resulted in a blank screen.
Steps to reproduce:
1. Open any 3D dgn example files in MicroStation 08.11.09.578*
2. Key in command : RENDER VIEW and select View 2 (Isometric View)
3. A blank screen is produced.
Note: The same file is tested in version 08.11.09.459, it rendered well.
* With Descartes 08.11.09.578
I am not sure if this should be a wiki page, because it's more like question to a discussion forum and it doesn't provide any solution.
From MicroStation help file: As of MicroStation V8i (SELECTseries 1), the radiosity, particle trace and ray trace rendering modes have been replaced by Luxology rendering.
It means these modes are not supported anymore and in my opinion the bug is not the key-in doesn't work, but that the key-in exist in MicroStation.
