Looking at the bug list for the patch I would have to say you all did a great job! I applaud all of the hard work you have done going from 1.0 to 2.1! For me, unfortunately you fixed a lot that I did not know was broken and little of what I personally use. I have not seen any difference with the patch, the one file that would not open, still does not open (sent in to eovia, though I don't know if the patch prevents the error in saving to occur in the first place so it may be fixed. Inability to render image until the file is saved and reopened, even after the patch happened once With one file, nothing special seems to trigger it, just render, change something, render, change something, etc and eventually after 10-15 it will no longer render until the file is saved, closed and reopened. SM, all dots still black, even the selected one. VM, well, until it is as functional (extrude, sweep, use quads, box model) as amapi it is a weakness, unfortunately Amapi 5 has some serious stability issues (and no car exp and no integration with Carrara). I was hoping that the VM would also get updated so that I would not have to enter 0 every time I wanted to extrude (should be free by default with a shortcut key) Copying a terrain and then pasting it and trying to move it results in an error until it is taken into the edit room, then it works fine subsequently. Open GL using a 32MB ATI All-in-wonder Pro is still to buggy to use (Artifact, layout changes, occasional rendering failed) I am happy to see the Booleans improved in the VM, great! All in all I am happy to see progress in functionality and stability for all platforms. As my skills improve I am sure to appreciate the fixes just implemented. Great job and keep it coming!
