I am investigating replacing my 2D terrain with new experimental PaperTerrains using splines & sprites. One thing I’ve noticed is that it isn’t making terrain as thick as I expected. There is a Collision Thickness setting which I’ve increased to 40, but it seems to end up building collision thickness at around 10, so about 1/3 to 1/4 of thickness I asked for.
Here I’ve placed a terrain spline into my map next to an existing sprite sheet that is 40 thick. You can see from settings terrain should also be 40 thick. I highlighted lines a little by hand so you can see what I’m talking about.
I don’t need a work around, since I just triple thickness that I wanted and it seems to be ok, just reporting so it can hopefully be fixed in 4.7!
