I've been experimenting with Caligari Truespace 3.2 This is a pretty groovy 3D editor. I've only just found it and have only briefly experimented but have successfully saved as .asc fileand then used biturn to convert the file to .ase so that it can be imported into Alice. A bit messy but I'll keep trying as this seems to be a doable work around. I'm a primary school teacher so I'm looking for something 10 year olds can handle.
