Hi Wolfi
I can confirm, that it works good.
Export works with it, atleast MD3 and MDM/MDX.
Maybe i exported to MDC too, im not sure

Some Import Addons are disabled by default in blender, and if you dont find what you want, there are several ones available online.
Btw. if you have missing Triangles after Export ingame, make sure the models are Triangulated.
