Hi performers,
I'm using a modell containing a structure of 3 layers.
This structure shares 1 large geometry and 3 textures (RGB).
Each layer got a separate value for the transparency-material-component
to support a blending of the different textures.

-->When I take a look on the modell from a bird's-eye-view (no
overlapping parts of geometry) all the textures are rendered in the
right order, inclusive blending.

-->But when I take a side view and there exist some geometry parts
overlapped by others in the foreground (and both surface normals point
to the eye) only the texture of the base-layer will be rendered on the
geometry of the foreground, INSTEAD of the texture of the decal-layer.

-->When I enable only one of the 3 layers everything works fine(side
view).

To avoid this failure I changed pfLayerMode and pfChanBinOrder but
without success.

Does anybody know what's going wrong ?

Peter
