The problem is that in hose you cannot use primitives other than triangles since every hose segment is someway different from any other.
Yes, you're right - even quads are not usable since they would get warped!

Maybe it would be possible for some parts to use a mixed mode approach? Fixed, non-deformable "middle" section, joined by a stretchable/deformable part? That wouldn't decrease the poly count, but create much more manageable file size.


Also, be aware from ribbed hose actual definition! It takes over 6500 vertex to define a single segment!
Agreed, present usage of tori in this part is total overkill!

Actually the amount of vertices aren't really a problem (besides filesize), I've tested setups using over a million triangles in a single flexible part, this part renders at over 1000fps. The only bottleneck is generating the mesh though like Sergio indicates. But because I work with 32bit indices anyway (some official parts have more then 65000 vertices) all the base mesh handling code is already there. And with VGA cards having a couple of gigs of memory these days all should fit nicely in vbo :)

As for mixed deform and references this is possible in the current version, so if you figure out a configuration which is the best of both worlds for the flexhose I would happily include it in the default collection of templates.
