NavMesh at Small scale

I’m remaking pacman as a way to learn ue4’s basic functions I’m using a 1u=1pixel scale and I can’t get the nav mesh to see the pathing. I’ve tried screwing around with the agent radius and max step height and pretty much all of the nav mesh generation settings. Does anyone have a good setting for tiny sized games like this? or do I have to start over with a 10u per pixel scale?

Here is my project file if anyone needs a quick pixel sized map to mess around in. https://drive.google.com/file/d/0B_V4K0ogv0EiTEFCbi1HZGxCcFU/view?usp=sharing

I figured it out, Agent radius and Cell size both needed to be decreased (Cell of 1 and agent of 4 worked for me). BUT I was altering these properties in the Nav Mesh entries in the project settings. The settings in the nav mesh instance did not change. Look for a second Nav mesh file that auto generates, not the volume itself.

Thanks for posting your answer! I fiddled around for a while trying it to get work and wasn’t making any headway - I didn’t even know that nav mesh file got generated.
