[ODE] Heightfield2

[LR]

Hi,

Thank you for the response.
I tryed to rotate hiegtfield and i can now use it as terrain, thank you :)

I tryed to change cylinder for capsules and it works really better: 
Cylinder jumps every transition (or near every), up to 10cm up
Capsules jumps 1 time for 10 transition,up to 2 cm up

Is it possible for you to try with capsules instead of cylinders? it is
possible that there's a bug in the ray / cylinder or plane / cylinder code.

I have seen this behaviour myself, but not investigated it as I assumed it
was the density of my heightfield grid rather than a common problem for all
cell edges.

Regards,
Dave
