I had great difficulty with Truespace 3.2 and 5....... and thought it to be worthless ..
That was until I saw what EvilGenius180 and a few others has been able to do. I could not model a box .. well I could only because its simple.. I have long since changed my opinion regarding TS ..
it depends on how you approach your work. Like Fretslayer said he coming from a director me I work like a modeller and less like an artist which is how I started .. with LW
and always I find it more difficult jumping between Modeller and Layout (the art bit)
