VaM 1.x How to prevent shadows on dildo? (make it match passthrough color)

[SirWanksalot]

I'm trying to make a default dildo object completely green to match passthrough color.
The goal is to make it match the passthrough color exactly.

However, I can't find a way to prevent any lighting or shadows on the object, which interferes with the passthrough coloring.

Is there any known method or plugin that makes this possible?
