too many primitives (65535 instead of 4294967296)

[Quadorrli]

hello

i'm trying to create a large terrain as IAnimatedMeshSceneNode due to LOD.

it's a lot of terrain
At some time the terrain disapeares and i get the errormessage from bellow.

it seems to have a maximum of 4294967296 but i can not draw that many as the errormessage states

does someone know why it says that the maximum of primitives is 65535 (which is the limit of u16) and not 4294967296?

Codeextraction from CNullDriver.cpp:

Code: Select all

//! Returns the maximum amount of primitives (mostly vertices) which
//! the device is able to render with one drawIndexedTriangleList
//! call.
u32 CNullDriver::getMaximalPrimitiveCount() const
{
	return ;
}


//! checks triangle count and print warning if wrong
bool CNullDriver::checkPrimitiveCount(u32 prmCount) const
{
	const u32 m = getMaximalPrimitiveCount();

	if (prmCount > m)
	{
		char tmp[1024];
		sprintf(tmp,"Could not draw triangles, too many primitives(%u), maxium is %u.", prmCount, m);
		os::Printer::log(tmp, ELL_ERROR);
		return false;
	}

	return true;
}
