Collision Question

How do you make a collision object that can be shot through, but not walked through? I can make the primitives in 3ds max, is there a special object property I need to type in, or do I need two collision meshes, one for the ‘special’ part and one for the regular collision?

First you will need to add a new ‘weapon’ trace channel to your project (under Project Settings), and modify your weapon to use it. Then select the object, go to the Collision section and change the Preset to Custom. Then you can choose how it responds to different sorts of traces and objects, so you can make it ignore your new weapon trace channel, but still block players. If you use this a lot, you may want to create a new preset with this configuration.
