Hey guys just a couple of questions, as I'm delving into Navmeshing for my hunting guild.

If I have a large flat space in an interior, can I simply drop 4 verts making a square shape, and create 2 large triangles? (obviously ill add smaller ones for edges where furniture may be). Basically are large triangles ok.

If I want to add a small triangle to the side of a large one, how do I make sure the verts I place will actually be attached to the Edge of the large triangle, and not just "placed" over it?

As always thanks for your help

I've never done any actual NPC movement tests to verify, but one of the videos (maybe a Beth one, I don't remember) mentions that larger triangles are more effecient. Which makes sense - more triangles makes more work.

All the triangles need to be attached. Each triangle is not seperate, so you don't want this:
I could try to explain the right-clicking to make new points for the triangle, but instead, I would highly encourage you to take a look at some of the navmesh videos. What would be hard to convey in words would be very easy to see in a video. Especially the Beth video that talks about "walking the dog". I think you'll find it pretty easy after you see a video.

Thanks Sollar I have watched them before a while ago now though, so maybe missed the info I'm after. Cheers mate.

_{Hopefully I answered your specific question, if not, just ask away....}

Yea the big triangles was the main thing the other bit I'll look at the video again and see about attaching triangles to eachother.
