Imported Asset Falls Through Floor Unity

I have not added rigidbody to the object.

Imported asset falls through floor unity.

I added a terrain object and gave it a texture to make my floor. One of the challenges i ran into was that when the player moved above a certain velocity it would sometimes pass through colliders. If your first person character falls through the floor of your game level you may need a terrain collider. He kept falling trough the floor.

However my object falls through the floor. I m using the official unity tutorial. If your floor really is a single solid object the next thing i d check is that the physics loop is running at a high enough frequency that the player can t fall too far into the object before the next tick. I created a plane in unity.

On the object i added a rigidbody and it already has a box collider. This happens most often when you fall between the cracks on badly modeled joined terrain due to floating point rounding errors. This will stop objects such as obj fbx max e. It keeps falling through the floor.

I figure i needed to add a terrain collider and then on the trigger move the rigidbody with a vector force of up. How to stop falling through floors and colliders in unity recently i have been working on a 2d platformer which uses the inbuilt unity physics and rigidbodies. How to set up collision. I want my imported object should behave like one created in unity3d.

But the imported fbx object as prefab falls down as game is started like object with physics component. I want to make a bouncing ball effect. Model created in unity eg gameobject create object cube is not falling down in y axis. Sweet then i added a rigidbody to my dude and added gravity.

The mesh does not align correctly to the character the character fell through. I imported the robot kyle asset from unity 3d.
