I have been working on the current scene below, and was told in the Works In Progress thread to have the glass cast a shadow onto the plane. However, despite how much I play with the settings I can’t seem to get it to work. Any ideas?
The two lamps above the glass were there previously. One is a sun lamp creating sky, and the other is a hemi providing basic light to the scene. I am trying to use the spot to create shadows…
With so little infomation (why are you so terrified to attach your blend file to your post) these are just guesses.
In the floor material have you set it to accept shadows
For the spot lamp have you set it to cast shadows
Increase the distance value for the spot lamp. The light strength may be so weak when it reaches the objects any shadows may be wiped out by the other lights in the scene. You can set the lamp to just cast shadows, not to light the scene.
Post you blend here http://www.pasteall.org/blend/. It doesn’t have to be the whole blend. All it needs to do is to be able to show the problem.
Looks like you have a general shadow problem as I can’t see the dice casting any shadows as well as the glass.
For the spot lamp turn on Diffuse, change its colour from black to white, increase its distance value to say 50 and increase the samples value to reduce the graininess of the shadow. Buffer shadows will give a stronger shadow but you will have to adjust the shadow settings
