VERY happy to see version 1 released at last - I've been using Anim8or since 0.6...
One problem I'm having with the latest version is with the shell function. When I apply it to a single-sided object which has shelled fine in previous versions, random spikes appear (see attached screenshot). Some of the new vertices appear to have been created a long way off their intended position. Simple primitive shapes seem to be all right, but more complex ones are not; I haven't worked out what makes the difference. It happens on a range of machines, mostly Windows 7 with one Windows 10, and is still there in the latest 1.00b release. I can go back to 0.98 and the same object shells as it always has.
Before I raise this with Steve, I thought I'd check to see if anyone else had seen the problem?
