Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

can't go inside house mesh

I imported a test mesh of a house from 3DS Max to UE4. When I drag and drop the mesh into the scene and hit play, I cant go in through the door as if an invisible wall is blocking the way. Sorry if this is a stupid question, but just wondering if anyone else has encountered this problem? I'm new to Unreal and just wanted to figure out importing before I move on. Any help would be greatly appreciated!alt text

The collision is not setup properly.

Go into the mesh editor for the static mesh (double click it in the Content Browser), go to the Collision tab, and select Auto Convex Collision. In the new box that pops up, you can increase hulls and vertices for more accurate collision. You'll be able to see when it's complex enough to allow for movement "inside" of it.

Preferably, create your collision mesh in 3DS max. That almost always, for complex shapes that need specific collision, results in better processing efficiency

Here's documentation on it. Should you go this route, you'll wanna create several convex hulls in Max that aren't intersecting, keeping it as simple as possible for your collision needs. You usually don't need collision meshes to fit your mesh exactly at every point.

Hey, it's a noob from the future. Things sure have changed since '15, what a simpler time it was.

Thank's for the answer. Helped immensely in my VR project.

No problem. I found creating custom collision in 3DS Max using the UCX_objectName to be very effective. Its also less taxing when imported to UE4.
