I have a little Problem with the texturing. I know, gmax is very old and working not very good in the win10 environment. But I am used to it and AC3D is a bit limited in functionality. I used the UVW Mapping for putting the right part of the bitmap onto the different parts. After exporting the mdl I import it into ModelConverterX and have wrong texture placement. Of cause, after creating the scenery it looks like MCX in AFFS2.
I guess, I need to use a different style to texture the tent.
