I try to optimizing the render quality of a 3D backdrop picture ... without satisfaction.
Perhaps somebody can help?!
My source is a picture with 1024x768 px.
3D world with same size on stage.
After addbackdrop in 3D scene the picture is a little bit blurred.
Thank you for your help.
All textures in Shockwave 3D must be power of 2 (e.g. 32, 64, 128, 256, 512, 1024) in dimension. This is in common with many graphics cards.
If you use non-power-of-2 textures, Director has to resize them before they can be displayed.
I suspect the resize method is nearest neighbor, which is probably why your texture appears slightly blurred.
Amazing! Thank you very much!
