Does anybody out there know of any good tutorials on level and character design using 3D GameStudio?
Try here for map creating tutorials, there is one for the version A6 at the top of the page, and one for version A5 at the bottom of the page:

Here are some modeling tutorials:

For creation of models I reccomend using 3rd party modeler, like Milkshape or simmilar, which is easier to use IMO.
Also, 3DGS modeler in version A5 and lower doesn't support bones system which makes animating your models a real pain in the ass.
