Irrlicht Engine

I think I've find the trick.

My function getBoundingBox in my custom node was not correct

The function doesn't return the good bounding box


With return the mesh bounding box, it is ok
Like This
//---------------------------------------------------------------------------------------
// Get box ...

Hello

I have made many tries but only setAutomaticCulling(scene::EAC_OFF) is ok at this time.
Also working with EAC_OCC_QUERY

My code for drawing the bounding box

void CGrassNode::render()
{

video::IVideoDriver* driver = _smgr->getVideoDriver();
driver->setTransform(video::ETS_WORLD ...

Thanks a lot Darktib, It's working fine with setAutomaticCulling(scene::EAC_OFF);

I've tried with almost all parameters but no EAC_OFF

Something to do with setMaterialFlag(video::EMF_BACK_FACE_CULLING,false) ?

I have tried with z-buffer true and false in Material buffer.

With the flag is set to false, i don't see my quads
With the flag is set to true, the problem subsiste

Something I've found : when the problem occurs, the number of Primitives is modified, it's decrease.

Hello

Is this a bug ?

I am trying to make a new scene node with grass quads.
I use a HillPlaneMesh and Meshbuffers
I draw some quads in MeshBuffers with DrawMeshBuffer

When i rotate my camera with a specific angle the quads are not drawn ???
132° in my sample.

The code below is just for test ...

Hi :wink:

I had the same errors recently when i've tried to compile irrlicht samples projects with spark dynamic libraries. (SPARK_project_1_05_04)
(I use msvc 2005 and 2010 express for my tests)

First, try to compile with static libraries.
Perhaps you will have errors on unresolved randomseed ...

Solved

Sorry

I've change this option in IrrCompileConfig
#define _IRR_MATERIAL_MAX_TEXTURES_ 4
to
#define _IRR_MATERIAL_MAX_TEXTURES_ 8

It's working like a charm 4000 FPS !!!

Thanks

Yes it works fine with your exe and irrlicht dll

Could you send me your modified irrlicht.lib file ?

Thanks

Hello 8)

Great job !!!
Thanks for your sharing

Unfortunately, I have the same issue than Shadowslair when i try to compile your sample.
The two versions are black
Radeon 5700
Your exe file + your irrlicht dll => ok

msvc 2005 + irrlichit 1.7.1
0 => black
1 => crash on m_MeshNode=smgr ...
