I've used glossy material shaders for a spaceship but, as you can see in the picture, the hand in the foreground is projecting a horrible shadow. I made the object shadeless but I lost the glossy effect as a result (this is because of the emission shader). Is there a way to keep the object glossy but shadeless at the same time? Thank you in advance!
The solution is to make the hand cast no shadow. The other object cannot be shaded (glossy) and shadeless at the same time:
If you want to tone down the shadows you can make it partially transparent for lights and shaded for camera:
Instead of blue transparency input grey transparent shader (so it's not tinted), and instead of green diffuse input your hand material.
One way to reduce the 'hard' shadow (rather than eliminate it completely) is to increase the size of the Lamp - since a larger lamp will produce softer shadows.
For example, the default lamp size of 0.1 produces an ugly hard shadow :
Increasing the lamp size to 1.0 produces a much less obvious shadow :
