openmw.org

That's understandable.

However, still, how can we contribute to development of openmw-template and/or OpenMW example suite?

For example, how would I edit terrain of openmw-template, so that it would become possible to reach top of mountain without resorting to noclip command?

Do it!
I would also like to contribute.
Could use a guide about what tools to use and what needs to be done.
