> Where can I get the HVA Editor to make vehicles moving like the Mammoth MK2 does? The Plasmadroid's site has a broking link so don't send me there. You may also send it via e-mail. And do I need to make an HVA for a vehicle like a Heavy tank?

http://www.alfar.demon.co.uk/ is DMZs page for it. As for the heavy tank, so long as you use an original tank for your basis and don't mess with the scale values you can just copy the originals .hva files and rename them.
