Can be set to 'yes' or 'no' and specifies that this terrain object generates Veins. It is not known if the Vein logic works in Red Alert 2 as it remains residual from Tiberian Sun.

Note

"It is not known if the Vein logic works in Red Alert 2 as it remains residual from Tiberian Sun" .
This logic still works in RA2,YR This tag allows TechnoTypes to attack TerrainTypes without forcing them to attack (by pressing Hold down Ctrl), even if the weapon doesn't have a tag TerrainFire=yes. (Work even though The weapon's warhead does not have a tag. Wood=yes,Wall=yes).
Disable IsAnimated even if set to 'yes' .
