Absolute Beginner question

Hey Guys its me and I am an Absolute beginner in unreal engine
For many years I have learnt game designing and now I wanted to bring it to next level
so the problem I am facing is how to assign mesh collider property to a mesh
as I have created a castle model and it is now getting a proper collider
Reply I you can help

Im not really sure what your problem is since it seems youre speaking in terms of how Unity works, and I dont know the equivalent in UE4. Are you trying to create a collision mesh for the castle?

If I understand what you are asking… you can make collision for a mesh you’ve made one of 4 ways.

The simplest is to select “Auto Generate Collision” when you import the mesh.
About the same is to Edit the mesh once it is imported and use the Collision pulldown menu to “Add” collision using the several options.
Both of these methods result in very costly collision in terms of system resources.

More efficient, but very time consuming (and frustrating) is to edit the imported mesh and add simplified Box and Sphere collisions, scaling and translating them to fit your mesh as closely as you can.

In many cases though, you will want to make custom collision as a mesh that you save in the same file as the object mesh itself.

I made up a quick tower to represent your castle mesh.

Notice the mesh itself has been named tower

Next I created a box and shaped it to fit very closely to the tower, and named it UCX_tower
UCX_ tells UE4 this model is a collision mesh, and attaches to the mesh of exactly the same name, and case matters.

Now select both of them and export/save them as a single FBX file.

Once you import the fbx you can edit it to see the collision.

(I did a quick bit of material work on it to make it more visible)
If the Collision mesh you combined into the object is visible as an object, you have the naming mismatched. Be sure the names are blahblah for the figure mesh, and UCX_blahblah for the collision mesh, and that the names are actually for the shape itself, not an action. Eg. In Maya, it will be the Left-most item you can name.

Once you get collision mesh to match up as you like, you’re ready to have things hit/block/overlap the figure.

If this wasn’t what you were asking, let me know and I’ll try to answer correctly.
