Welcome, zuter: As you may know, you can read a lot of back pages and search by keywords to locate discussions that may be related to a question. If you have questions related to Sketchup, a specific rendering application, or a script/plugin, there are many here who can answer or point you in the right direction. If you have been using Sketchup since version 3, you may have insight for others, so, don't be a stranger.
