Worst of the Worst
If you want a 3D package that works, stay away from this one. I purchased te Strata CX Pro (version 4.0) and had nothing but problems. When I loaded it, and tried to open it, all it did was freeze up, and then the entire screen turned white. I posted on the StratasCafe forum, and received an immediate answer from a Strata Rep (good service for bad product) and received a link to a posting on the forum that explained in detail some major problems with Strata, which the company blames on the Graphics Accelerator card manufacturers. Apparenty if you have anything other than an onboard graphics system (built in to your main board) then you will have major problems with this program. Since there are so many different possibilities with these cards, nobody can quite explain what it is on each card that helps fix the problem. One person suggested to turn tha hardware acceleration completely off, which allowed me to open the program, but everything moved really choppy and it was horrible (I have a 512mb graphics card). After battling with this program for awhile I gave it away (I couldn't justify re-selling a piece of junk like this) Hey folks, even Blender runs better than this ... you would be better off downloading it from free at Blender.Org than shelling out more that the price of the plastic and cardboard for this sorry software.
And get this ... Strata puts all the blame on the graphics card manufacturers!!! I currently have laoded, and work in Newtek Lightwave 9.0, Carrara 3d Pro 5.0, Adobe Photoshop cs2, After Effects and Premier, Vue Infinite 5.0, Amapi 3d Pro 7.0, and several other programs, and I have never seen anything like this ... all the other programs on the market work just fine with all the major graphics accelerator cards.
So, in a nutshell, if you want to avoid wasting several weeks or months trying to get this up and running, don't buy it. If you have a generic storebought proprietary machine, this may be the product for you ... but don't buy it, wait until somebody like me gets frustrated with the incompetence of the programming and gives you a free copy!
