Unity Noob, falling through terrain problem

Hello,

I’ve just started working with Unity and have jumped in feet first. The first problem I have run into is the construction worker falling through my terrain as soon as I go to game preview. The camera follows him right through the ground then stops and he falls until I turn off the preview. I have made sure his feet are above the ground and have even placed him a few pixels above the surface to make sure. Can anyone tell me what is causing this?

Thanks

Does your terrain have a collider?

Does your construction worker have a collider + rigidbody?

Yes the terrain has a collider. Not sure how to find the colliders or rigid body on the construction worker

Look for a Character Controller on the Construction worker if it has one that is what Unity is using for its Collider and its normally small and will fall through if you do not adjust it. Just click on the Construction worker in the scene and look at the left panel that has the attached scripts and things. If its not on it then it may be on the child object mesh of the construction worker.

Also, make sure your construction worker starts out above the terrain so he falls onto it.
