Hello! I am trying to make a circle mesh hollow on the inside. How may I do that. I am new to UE4 so sorry if I don’t know much. Thanks in advance.
what do you mean? a circle by definition has no depth so it cant be hollow. if your talking about a sphere mesh well all meshes are hollow. so im a bit confused on the question. provide some more details and a clearer explanation.
i have a feeling though that you are creating a mesh in a a modeling program or are drawing sprites based on your other previous questions.
so I tried to make a hollow sphere in blender. I made it but on Unreal Engine it looks like this: Sphere Mesh - YouTube
Also, I would like for my character to fit in the hollow sphere. So I then tried to ask if there was a way to make the sphere hollow in UE4. That is my situation.
what you made looks like a sphere with a hole in it not exactly hollow. im guessing what your trying to make is something cave like. to do this and for it to look and function right you need to have mesh faces everywhere the player can see, so you need faces on the inside and outside of the mesh. the easiest method in blender to do this is to use the solidify modifier. you will also need to have a hole in the mesh for the player to enter if thats your aim. there is no method to do all this in unreal so you will need to make the modifications in blender. you will also need to create custom collision or use per poly collision but thats another subject entirely.
if you want to know the reason why you need faces on both sides look into normals, but the basic explanation is that geometry has no depth, so when viewed from the wrong side its invisible.
Thank you so much. Do you know a tutorial I can follow to make it? If so, a link would be appreciated.
i dont know any tutorials about that specific thing, but i basically just showed how to do it. you just make a sphere, then go into edit mode and delete the faces you dont need / modify the shape as you desire, then go to the modifiers tab and select solidify. i know your new to modeling but i dont know how to make it simpler without saying each button to press. if you look at the picture above you will see which tab is the modifiers (the wrench or spanner) then you see the settings i had when i made the example mesh.
