Bad Auto collision

For some no important assets, such as trees , I will use auto collision. I tried to use auto collision for a room but the result is so bad. My character can't go inside and the collisions are so ugly. Therefore, I found a way to solve this problem by making collisions by myself.

Collision made by myself

The house is quite important, so I make the collision very detailed. I learn the naming way from the website I paste on the top.
