Thanks for the info. I will try to convert my model to triangles in 3D
Studio Max.
[3ds]
Yes, I do have
/usr/lib/libpfdb 11> l libpf3ds*
lrwxr-xr-x 1 root sys 17 Feb 8 1998 libpf3ds.so -> ./libpf3ds_ogl.so*
lrwxr-xr-x 1 root sys 19 May 25 1998 libpf3ds_ogl.so ->
./libpf3ds_ogl.so.4*
lrwxr-xr-x 1 root sys 617940 May 25 1998 libpf3ds_ogl.so.4*
When I run perfly, I got:
12> perfly 3daffleck.3ds
