weapons or other things invisible

hi,
what color do I have to take if I want to make the weapon ingame invisible???

I hope u understand my bad english -.-

I tried to delete the weapons. But than ingame they were white...

You need to enter the scary world of the ALPHA CHANNEL 0_o . read tutorials, it's hard to get @ first but it's quite easy really, there are loads of tutorials and threads on this

can u give me one which is easy to understand because my english is very bad

this isnt about making weapons disappear i would like to know how do i attach weapons using triggers. i cant seem to find a tutorail for it

You download a weapon model and use the trigger "Special Effect - Create" or something like that and attach the weapon model to your unit.
