3 questions about hydrax


20-10-2014 13:04:42

It's almost done to integrate hydrax into my scene, now I have 3 problems feels hard:

The surface looks weird when place the camera at certain position and direction(look down near above water).
I found the surface smaller then the viewport (see attachment a1 and a2)

Trees and grass have transparency problem in sight toward far water (see attachment b1).

Can't see any foam.
I have set foam on inside the configration file:


Is there mis-config or somethings special must be done to get foam visiable?
Thanks for any help!!!

BTW: I use hydrax0.5.4 with ogre 1.9.0 (also skyx0.4)
