This question already has an answer here:
is it possible / / how do i make an object give off "godrays" so that, for instance you can see it through slits in a wall?
I'm trying to make this, (an icosphere with a sphere inside, the inner sphere gives off a blue glow) into a sort of "disco ball" is the best i can describe it. but i'm fairly new to anything blender and have no clue how to achieve this.
I read somewhere that the only object that could give off volumetric light is a spot lamp, but the thread was like 3 years old.
Edit: thanks for the help, what you said to do worked, just can't have a material output and lamp at the same time apparently :D but that's fine it looks good now!
