I cant use a lot of the modeling tools while using the catmull-clark subdivision mode. Smooth shift destroys the model as well as a few other tools.

Anyone else having these kinds of problems?

okay, it seems that this problem may be related to having edge weights applied to the model. So far i've noticed that if I have no edge weights the knife tool as well as smooth shift seem to be working okay.

I'll keep pluging along to see if theres some kind of work around.

Anyone else notice this? You can do a simple test by creating a box, then subd using catmull, then start using the knife and smooth shift tools after applying some weights to edges and *poof* the model gets all screwed up.
Like the polys become disconnected.

strange that no one else has mentioned this.

nevermind, it still screws up without any edge weighting.


what gives??

Well, I think there are some issues still to be resolved with the CC's yet.

But as far as smooth shifting, what's the shape? I just tried smooth shifting a bunch of different number of ojbects and selections and didn't have a problem with CC's.

I didnt save the model but will try to replicate it and then will upload it.

After trying to replicate it for about 10 minutes now everything is working:grumpy:

go figure...

BUT if you apply edge weights to the model it WILL happen. I took off the weights but it would still happen so...

i'm baffled. Does seem to be related to weights though.

I'll make it happen again and upload

try this.

I didnt apply ANY weights prior so its not a weight problem.

BTW, im on a Mac. Does this matter?

Thanks for ny help!

Well, after taking a look at it I can see why your CC's aren't working.

The points at the corners of the polygons aren't merged. Did you do something to unweld them?

Hit M to merge your points and then try your CC operations again.

I noticed this to now. BUT I did NOTHING to unweld them!

looks like a bug.

thanks for your help. I really appreciate it!
