Thanks for your comment.
For my renderings I'm using PTC Creo Advanced Rendering Extension - I like it and you can see that it is easy
You can see here my last video tutorial: How to... ADVANCED RENDERING with PTC Creo Parametric 2.0
- Yes, you are right. In the future, I expect full window real time preview rendering. The small preview window it is not enough at this days for complex rendering (whole scene).
