Alpha Shadows

[anchuvi]

I have a poly plane with a texture on it. The texture has an alpha as well as a texture being placed in the transparency section. This all looks fine int he viewport.

Firstly, if I do a shadow map render the whole plane casts a shadow rather than just the part that is visible (on the texture).

Secondly, if I do a raytrace render the transparency works but not fully so you still see a faint shadow cast from the whole object and a full shadow from the solid part of the texture.

Any ideas whats wrong ?

Sounds like the values for transparency aren't actually %100. What format is the image... iE if the transparency texture is a JPEG the values have probably shifted due to compression.
