Maybe I am really stupid, but even after reading the manual carefully its not working. I am using the Poser 4 T-Shirt and a texture-bmp which was created for the Poser 4 T-Shirt. When I add a "2D Texture Node" and select my shirt.bmp texture as Image source, on the picture below it shows up beautifully, both the back and the top of the shirt. Texture strength is set to "1" but the shirt in my application does not change at all and stays white. Did I miss to select some option?

Make sure you pull down the little arrow to the right of the title "Material:" - you are probably applying the texture only to the preview part. Quick tip: Right click anywhere in the material room and click on "Select all", then right click again and click "Apply to all." This will add your texture map to all parts of the figure. TAKE CARE though - it won't work correctly for figures which use different maps for different parts, and will also wipe out any trans maps already applied.

Thanks for you picture, that was just hwat helped me. Thank you so much helping me :)
