Irrlicht Engine

I found some interesting thing:
when I use such code
pID3DDevice->SetRenderState(D3DRS_ZWRITEENABLE, FALSE);
setTransform(video::ETS_WORLD, ident);
q[qn]->Query->Issue(D3DISSUE_BEGIN);
SMaterial matetial;
matetial.BackfaceCulling = true;
setMaterial(matetial);
#if (FALSE)
drawMeshBuffer(q[qn ...

May be anyone can say me how save zbuffer to file for watching it later. Thank you.

I'm trying to use:
pID3DDevice->SetRenderState(D3DRS_ZWRITEENABLE, FALSE); - when I want just to test for visibility of BBox;
pID3DDevice->SetRenderState(D3DRS_ZWRITEENABLE, TRUE); - when I want to change zbuffer. Is it correct? I read documentation, and as I understood, it's right. But it does not ...

Thanks for your help. I'm trying to use this.

I have one more question. May be who better know Nardo's project can help me. Nardo's code likes this
Query[current]->Issue( D3DISSUE_BEGIN );
{
for(int scurrent = 0; scurrent < QueryMesh[current]->getMeshBufferCount(); scurrent++)
drawMeshBuffer(QueryMesh[current]->getMeshBuffer(scurrent ...

Please post here not only patch but the patched files (.h, .cpp) too. I have some troubles with patching. Or mail it to me please (naxart@gmail.com).

Thanks.

I have a big troubles with patch. I tryed TortoiseSVN and patch.exe for update code. But always got errors like "patch seems outdate". I tryed "update to revison 1498" and the same result. I tryed patching code of 1.4.2 realese - and the same result. May be some one can mail to me patched code of ...

Is Nardo project included 1.4.2 realese ? I still don't download it. I use 1.4.1. Or I should use his patch for update source (I'm not good in svn) ?

search in forum or in google?

I'm interesting in: is irrlicht not render objects that overlapped by some objects when we see from camera. I mean is there some kind of algorithm done? For example, we should stay flag that object (or it's boundary box) is not transparent, so during rendering engine skips objects that collide by ...

gravity is (0,-50,0)

And I have nearty 6-8 fps with my big scene.

I have a carema a CollAnimator:

scene::ICameraSceneNode* camera = smgr->addCameraSceneNodeFPS(0, 100.0f, 300.0f, -1, 0, 0, false, 0.f);

scene::ISceneNodeAnimator* anim = smgr->createCollisionResponseAnimator(
metaselector, camera, core::vector3df(20,80,20),
gravity,
core::vector3df(0, 70, 0 ...

I need a context menu with large depth of submenu.
for example DIR_1->DIR_2->DIR_3->DIR_4->DIR_5->ITEM

Problem with drawing of this structure.

In "windows" when submenu goes out of window it draws on other side of parent submenu but in irrlicht doesn't. Is it a bug ?
