shadows in NxOgre0.5 preview2.0

Due to some time lag problem between sensor movements and graphic models, I have to stick to old version of NxOgre.

I noticed that in NxOgre0.5preview2.0 version, all examples in tutorial have no shadow. Where shall I change to turn on shadows?

By adding some shadow code, or uncommenting it out. I can't remember which.

My I ask, why is there such a lag problem that you have to use such a horrible old version like that?

Thanks for your reply.

I've post the time lag problem here before:

The lag is significant and not acceptable in newer versions.

For the shadow problem in the old version, I have checked nxOgre_body.cpp of that version.

in body::body(.....)

if (_meshName != "") {
mEntity = owner->mSceneMgr->createEntity(mName, _meshName);
mEntity->setCastShadows(true);
mNode->attachObject(mEntity);
}

That seems okay that any body created should castShadows.

Also I checked TutorialSimples.h of that version.
TutorialSimples.h -> run()

mSceneMgr->setShadowTechnique( SHADOWTYPE_STENCIL_ADDITIVE );

seems fine as well.

Any clue where I shall change to add shadows in the old version?

I am now comparing the tutorialApplicationDragon.h of the latest version with the tutorialSimples.h of the old version. Still have no clue.
