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 climb a simple slope

Hi, I wanted to be able to climb a slope but unfortunately can't find anything working.

I should be able to climb near of a 45 degree angle but as you can see in attach, I can be happy to climb a 10 degree. I have no collision on it, it's a Landscape ramp.

  • I tried to change the CharacterMovement Walkable Floor Angle up to 90 and rebuild the project.

  • I also tried to change the CapsuleComponent and my Skeletal Mesh to enable the Physics Walkable Slope Override, set the options to Increase Walkable Slop and set the Angle up to 90.

  • I activated the Navigation visual debugger and it never changed whatever I do.

  • My CapsuleComponent is Scaled to 1/1/1

  • My Skeletal Mesh is Scaled to 3/3/3

  • My Viewport Character is Scaled to 1/1/1

I tried what I could find in the forum, hope you will have an idea ^^


It's like I can only walk if the floor is not too high. I can't move on a landscape if it's high like 600 or 900 in Z axis, but I can move if the floor is about 200 in Z axis. That's why if I create a hole in the ground, I can on walk in the hole.

That's weird May be try decreasing gravity or any downward force on the character.

Ok I found a solution :) It was my bad, I totally forgot about the NavigationMeshBoundsVolume. My map became a little big and the problem came from the slope, I didn't suspect the limit of the navigation box.
