Hello.
I’ve been working to get some height differences into my playfields. Most has gone well so far, but there are these seams that appear between the modified Quads. I assume it’s a rounding error or something like that. What can i do to get rid of them? My quads are 4 units wide. Do i have to scale them up?
Why can’t i edit my posts?

You can edit it, press the “edit topic” link further above.
I thought i would just edit the “topic”, then. duh 
Anyway, i solved it while trying to solve something else. I don’t know why it occurred though.
For my normal buffer, i had just set the normal for 1 vertex (which yielded acceptable results anyway).
Now i filled the buffer for the other vertices as well, and the problem disappeared.
