Maxwell for SU VS Twilight

[Fletch]

For future reference on the Twilight Render website there is a "Tutorials" link.
There you will find the video tutorials for Twilight Render SketchUp plugin. They are made in such a way that people that do not understand spoken English so well can still learn how to use the plugin. (Videos are also available in Spanish and Japanese)
The next place to go for beginners would naturally be the FAQ section of the user forum. In this case, it is not a list of some odd made-up words that no one actually ever asks about. No, it's actually a list of the most frequently asked 'beginner' questions.

Warming up the sky: There are many controls for physical sky, and color of sun, sun radius (how soft the sun shadows are) in the Light Editor dialog for Twilight. Check these tips for beginners wanting to warm up the sun and sky, and speed up renderings and general working in SketchUp:
Default Sky Setting for Twilight... and speed up SU (includes an excellent default sun and sky .skp template file)
First thing to do to warm up the Sun and Sky
In addition of course you can use any spherical sky image in .hdr or .jpg format.

If somehow the User Manual (comprehensive, fully hyper-linked, well organized, and searchable) does not have an answer to your question, you can check out the Best Of Tips and Tricks - The Master List

Lastly the Twilight Render community forum is very friendly, helpful, and welcoming to all. It is very similar to the lovely folks here at the SketchUcation forum.

Finally, users of the free trial still get free support from our user forum. People who purchase a Twilight Render license get access to the Red Carpet Section of the user forum, a lot of free advanced video tutorials, user content, scenes, etc.
