physx collision mesh

[nayan]

this is the first time I have noticed,
if there is no velocity on particle object, then physx collision mesh - hull type "Mesh" which is animated doesnt have any impact on the physx shape particles....this is wierd....I think physx collision mesh doesnt not respect animated mesh transformation as velocity. 
But if I throw the particle on the physx collision mesh object - works.....
Kinematic not working....

The same problem arises if two different events are made with one physx shape particle and other with physx shape mesh as kinematic, again if the particle doesnt have any velocity, kinematic mesh doesnt not collide at all.....

Is this a bug or an issue or this is how physx work?

Thank you
