Bah this makes no sense ><

Newton crashes when trying to make a tree collision in the new build (200).
How can the arrow even get inside there because the variable is clearly smaller than it tries to check against.

My guess is that newton doesnt like large face datas (2mil+ polygons)
I dunno what to do, sometimes I hate programming

some how the number on entry is 1 billion points, if you mutiply that by the tyope size wih I beleive is a vector (16 byte) that is 16 giga byte whu will crash windows.
32 bit windows has a memory limit of 2 gygabytes.
if you are going to make collision tree that big, you will definitly have to use 64 bit windows, or brake then into smaller maps maybe a quater of million faces each.
the scene collison let you add then all to single shape.

what kind of collision tree is that?
if this is a heightfield you can just use the Heightfield collision instead, it will use few megabytes instead if few Gigabytes.

you say you are passing 2 million faces, that dos no soudn liek it will use that much memory.
2 milion faces assuming triangles, will use 2 * 3 points * 16 bytes = 48

around 100, maybe 200 begabytes, but it seems your using 10 time that, you should be able to add 10 million faces without problems.
