Well I thought this was going to be too complicated for my wee brain to grasp, but after reading the posts and seeing what people were doing I decided to give it a try. (even forced me to figure out how to export as an obj so I learned something new as well) :)

I will echo the slider/dial rather than text boxes request.

I extracted it to D rather than C and it worked, but crashed on trying to save so I moved it to C and now it freezes trying to save (vs just shutting down completely which is what it did on D).

Any suggestions for getting save to work would be great.

Thank you for sharing this with us. I can see a lot of potential for it with this community.
