When i make a simple box with one side open in my 3d software (c4d/3dsmax) and save it as FBX file, i can’t go into the box, even though its spacially correct, visually speaking.
Is there a way to solve this, or maybe another format that does support that?
thanks

Are you saying the collision isn’t working right? Have you read this over? https://docs.unrealengine/latest/INT/Engine/Physics/Collision/Reference/index.html
Make sure to take a look at this video: 
Look at your collision mesh. If you just import a box UE4 will likely create a box collision (6 sides), I’ve noticed that it doesn’t always understand that you want one side open (which actually makes perfect sense when you think about it). You might have to tell it to leave the open side … open. LOL
