Hi,

I use Hexagon and I make an amount of my own props and clothing for Poser for my own use.

It seems to work quite well with Poser and hasn't caused me any issues.

Pretty much any modelling application that exports obj files (all if not most of them) will do the trick.

I also suspect that the higher end, the modelling application is, the more you'll get out of it.

Having said that, there are some free ones that have good reviews and many people use them.

I'd download the demos and see which one you like.

Cheers,
