Terrain area wont render (Irr-Spintz)

[Warchief]

Im having problems with Terrain. Sometimes, when i move the camera, terrain areas that should be rendered, are not actually being rendered.

The picture shows what i mean.

Code: Select all

ITerrainSceneNode*	m_terreno;

char sueloPath[256];
sprintf(sueloPath, "%ssueloHeightmap.jpg", PATH_COMUN);
m_terreno = SMGR_PTR->addTerrainSceneNode( sueloPath );
// Escala
m_terreno->setScale(vector3df(0.25f, 0.1f, 0.25f));
m_terreno->setPosition(vector3df(-45.0f*escala, -2.2f*escala, -45.0f*escala));
m_terreno->setMaterialFlag(EMF_LIGHTING, false);
// Textura
m_terreno->setMaterialTexture(0, RES_LOADER->GetTexturaTerreno(0));
// Sin textura de detalle
m_terreno->setMaterialTexture(1, RES_LOADER->GetTexturaTerreno(1));
m_terreno->setMaterialType(EMT_DETAIL_MAP);		
m_terreno->scaleTexture(1.0f, 50.0f);

Im using Irrlicht-Spintz. Is there something i am missing?
Thanks in advance.

Does escala change very often? Since you change the position of the map, you also have to recalculate the triangle selector and stuff when you do this.

I think this might be a problem...but dont take my word Im still new.

That has to do with the frustrum culling. It's a bug, I'll look into it, thanks

It also happens when camera is initialized at Z axis (plane x=0). So i think its not really about the camera movement, but a small bug in calculations, as Spintz suggested.

I'll be waiting for solution. Thanks.
