I have been creating an interactive environment for the last week or so through a 3D Scene exported from both Sketchup and 3dsmax. Things are looking good and going okay but when I started to set up wall collisions, I noticed the character in play mode would go through the walls I had just set up the collisions on. I had started the project with the FPS blueprint template. I did edit the BP to eliminate the camera, gun, shooting and such but that should not have impacted the collisions. I spent hours today searching the web for possible remedies and thought I found some but they did not work. I have selected on the wall mesh objects and opened in the editor to make sure collisions were enabled. Can anyone help me out with some thoughts on what to do?
