One issue is that in the official tools release, many of the skins for the misc_model models are missing; they can be collected from: here.

This info was found by Krekits at the rust Wolf forum, here's the original message.

An excerpt from the msg:

There is onbly a short german readme in it, because I made it just for myself and decided later to share it with others. Here's a short descrition:

• download the zip file
• extract it with winzip
• please select to "Keep the folders" when you extract it, so the skinfiles will automatically extract into the right folder. (ex: mapobjects/furniture skinfiles to mapobjects/furniture folder)

I use an external program named "3D-Exploration" to preview and select my models I want to use. It's faster then testing all in the radiant.

If you have any questions, problems or find solutions regarding this topic, please post them in the QuArK forum/mailing-list.
