Ever made over lapping sectors that where visible at the same time and created this glitch?
So, what what if I told you? There is a simple solution to this Build Engine rendering issue.
It's because the Engine, doesn't know what to render first. Now, let's look at those sectors.
See, here's the problem. The sectors are in the same area. Being seen, at the same time.
To fix it, turn those sectors into pizza slices. Well, it's more like cutting the sectors based on the angle you'd be looking at. But we like pizza. Now let's look at those newly divided sectors in this picture.
By doing this you're giving the Build Engine the ability to show both sectors at the same time. Remember this is based on the angle you would looking at it from. So some slices, might be thinner if need.
Here's an example of how it looks during rendering. You should noticed it rendering properly.
See, no more glitches. This also fixes a clipping issue when you shoot into the render glitch. Something that polymer can not resolve. Even though it renders properly. The clipping issue will still be there.
Thank you for reading this. If you'd like to see the map to gain better understanding of this?
Here's a link to the map in all these pictures.
