Please post if there is anything I should change before adding the text to the “Performance Issue: Python Calculation” page.
@zonzagolo: Sorry, but there can’t be a single page for “how to get stunning rendering”. I’ve never seen anything like that in other engine’s documentation as well. it wouldn’t make much sense, there are hundreds of ways to make your scene look better, each deserving its own topic, stuffing them all in one page would be a bad idea. If you would read some more of the manual, I’m sure you would learn “how to get stunning rendering” by using different features explained in different pages.
I would suggest the pages about the “Shader Generator” and “Common Image Filters”.
