I'll post a .pz3 if you like, but first just try viewing the scene from the Shadow Cam of the light that is casting the shadows of the transmapped object. (select it from the list of cameras in the pulldown menu under the scene display window) From this view: - Make sure the object is actually between the light's ShadowCam and the location you want the shadows cast. (To make it easier to move, parent the object to the light if you haven't already.) - Use this cam's Zoom dial to get the scene to fill the frame. The more it fills the frame - the sharper the shadows will be when rendered. If it's just a tiny bit of the frame, the shadows will be too diffused to be seen. Waiting on a render using your transmap image posted above.
