Being able to go through a mesh?

[spikezz]

Hello, The title says it all. But, Yes, I've been having problems. When a mesh isn't supposed for you to go through them, such as I downloaded a desk chair... And I can go through it?
If you can help me, Greatly appreciated!

You'll have to set the collision for that particular object. Simply open up that mesh in Object Maker by typing out the file name where it says "Mesh," located in the Mesh tab. Once you've got your chair, simply check the box that says Own Collision. That will, of course, give the object collision for your character to walk, stand, or sit on. I do hope this helps.
