    How do I set up a collision mesh inside Blender?

    Hello Epic Games Forums,

    I am wondering how do I set up a collision mesh inside Blender 3D? I have tried just importing assets to the UDK but it complains about the asset not having any collision mesh.

    Please help me, thank you!

      Thank you very much for your help. I did not know the mesh had to have a UCX_ prefix.

          If you are using blender 2.5 and exporting the object with fbx. Dont forget to apply the scale to your collision assets.

            So far as free apps, would you recommend Blender over Milkshape for static and skeletal mash. And is Blender 2.5 best as I can download a previous version ?

            I have nil nexperience with any of these types of Apps so Im in for a steep learning curve.

            Thanks.

            Mik.

              I have only tried blender and quite happy with it. Use the newest 2.5 RC version. as far as i know, most of the modeling applications are same, and excel in only few categories from each other.

                Thanks for you sharing your expericence. I had both milkshpe and Blender on my mind today. I considered maya Student for about two minunets. Out of the other two I was already swerving toward Blender. Excellent to hear you like it.

                  But you can create a collision mesh inside UDK for a mesh ?

                    I think this is a question, so the answer is yes.

                      What is the big difference.


                      Ive only got a few hours up on both UDK and Blender. Ive played with adding collision meshes in UDK and that tool seems pretty good. Is the reason for making collision meshes in a 3D app partly to do with making a destroyable object mesh in the 3D application ?

                        Create a collision model in Blender around your original model.
                        Name the collision model the same name but with the UCX_ extension in front of it.

                        Example:
                        1. If your model is called CyborgRaven,then call your collision model UCX_CyborgRaven.
                        2. Select CyborgRaven and UCX_CyborgRaven and export them as one model.
                        3. When you import into UnrealED and open in the StaticMesh editor then UCX_CyborgRaven will automatically be assigned as the collision mesh.

                        I hope that helps you.
                        Good luck.

                          To add to this... Make sure your collision model is a convex shape and is as simple as you can make it. You can create multiple collision models per mesh.
