is there be a video on this? it would simplify this topic so much for me if I watch a tutorial on it.

I made a oxygen tank replacement misc item for pyro, im trying to make the crystal transperent like a diamond bot killer robot head and get rid of the oxygen tank since its just clipping through.

This is a screenshot of the misc item. [40.media.tumblr.com]

This is the first time I have ever made TF2 item... so im kind of a noob....
