Volume section missing in material panel I'm new to blender and trying to fiddle with materials. However, in the materials panel, the volume section is missing. 



I'm using Cycles. Is there something more to enable somewhere ?
if you are using cycles you need to check the "use nodes" button in the screenshot above. once you have done that i suggest using the node editor to work with your materials instead of the properties panel shown in the image. if you need help using the node editor ask and i can help. i do not know much about volume shading in particular but i can help with nodes.
