He has used Infini-D 4.5m on the Mac mostly as his 3D tool. I know he also has Carrara, but don't know how much he has actually used it. He does use Photoshop quite a bit too. I also own Infini-D 4.5 and can see why he has stuck with it...easy to use, straightforward interface...just my opinion thou. Actually, again IMO, Cinema 4D core is more like Infini-D 4.5 than C3 (which is more like Ray Dream). But most importantly...it's the artist, not the tool...and Brian proves this.
