Imported Asset Falls Through Floor Unity

I created a plane in unity.

Imported asset falls through floor unity.

How to set up collision. I have not added rigidbody to the object. Sweet then i added a rigidbody to my dude and added gravity. This will stop objects such as obj fbx max e.

I m using the official unity tutorial. However my object falls through the floor. This happens most often when you fall between the cracks on badly modeled joined terrain due to floating point rounding errors. One of the challenges i ran into was that when the player moved above a certain velocity it would sometimes pass through colliders.

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. If your first person character falls through the floor of your game level you may need a terrain collider. I want to make a bouncing ball effect. I want my imported object should behave like one created in unity3d.

I imported the robot kyle asset from unity 3d. But the imported fbx object as prefab falls down as game is started like object with physics component. On the object i added a rigidbody and it already has a box collider. 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 added a terrain object and gave it a texture to make my floor. Then added a rigid body the character fell through the plane i then added a mesh collider and attached the mesh for the character to the collider. He kept falling trough the floor. Model created in unity eg gameobject create object cube is not falling down in y axis.

I figure i needed to add a terrain collider and then on the trigger move the rigidbody with a vector force of up. It doesn t work.
