From another forum I hang out on:
Hi, I just got an email from Caligari regarding TruSpace 7.6 absolutely free - comes with manuals and tutorial videos. For those that don't know TruSpace is a 3D application (one of the first from the old days and has been still supported over the years). I think the reason they are releasing this freely is because they are trying to get more people actively using it.
Still, it seems quite comprehensive and may help the budding UI developers here do some magic. I've downloaded it myself and am planning to give the program a chance since it's free and I'm a total noob when it comes to 3D. I've tried Blender and Wings3D which I can handle to a certain extent but TruSpace package seems to have more friendly approach and explains everything.
Anyway here is the link from email:http://cart1.caligari.com/web/Truespacemainreg.aspx
I can verify that the files are virus free and not a scam or anything. I've just installed it with the manuals and PDFs and videos. Total size is around 321 MB compressed.
Posting this on the forums to spread the word.
I grabbed it, registration is required, but it seems to be pretty relaxed about what you type in the required fields. It emails you a reg key, so don't provide a bogus email address, but otherwise you can register as your goldfish or whatever.
