hey thank you for ur help.
when i do engine preview he Shows me following error: Malfunction W1301: "-S: Can't open file". He's still showing something however and the shape is right, but everything that has the Wood texture for example is Brown and the Skins without an Image are not shown ( or to be more precise they are shown as White). In the Skin Manager i adjusted the wood Skins (with Image; linked it with the bmp). There are also other Skins but they are foreshadowed Grey even though they have the right "diffuse" under manage Skins.
