Help with importing blender enviroments

I downloaded a blender prison model from blendswap and I imported into unity but the player just walks through the walls and stairs, how can I fix this?

 

I hope I read your question correctly.

Did you add any Colliders?
eg. Box Colliders etc. to the prison model?
If not, that could be one of the reasons, why your player is going through the prison model, like Shadow Cat from X men.

Check this out: http://docs.unity3d.com/Manual/CollidersOverview.html

If the objects in your prison model eg. walls, floors, boxes etc. are made up of seperate objects or other.
A few Box Colliders on each object might help.

I hope I was able to help you!

 

Thanks that helped!

 

Yay!
Glad I could help!

 

I hope you can help me with texturing the ground as well, everything textures perfectly except for the ground the texture always seems stretched out. TY in advance.

 

Show me a pic of it.

 

it's supposed to look this way:

but it looks like this:

 

That would be an issue with UVs. They need to have less stretching. If you are doing some sort of automatic UV-mapping, you will need to modify it afterwards. If the area is pretty flat, the quickest way is probably just to do it with a quick planar mapping.

 

I was now about to say that this could be a UV mapping problem.
But I was beaten to it!
