Slum

Stumbled across this a few minutes ago. I haven't checked it out yet, but I thought I'd mention it here. From the looks of it, it doesn't seem like it's going to kicking mudbox to the curb just yet, but it's free.

Hey, at least its a open beta like zbrush was.

It seems very awkward. I can imagine a LOT of pushing/pulling to get anything decent. I noticed that you can't mirror a mesh, then tumble it, you're locked to orthographic views, and there's no real 'draw' tool. I got the best results drawing freehand curves then pulling/pushing them around... But then it IS free, and still in development.

I'm playing with Sharp Construct at the moment, which does much the same. Not a Zbrush or Mudbox by any means, but useful.
