Loading large 3DS mesh goes quite wrong

[Jimbo]

When trying to load quite a large mesh irrlicht crashes. Diving into
what's happening I found the following:

Code: Select all

void C3DSMeshFileLoader::readVertices(io::IReadFile* file, ChunkData& data)
{
	file->read(&CountVertices, sizeof(CountVertices));

CountVertices is declared as a s16 (signed short). I've changed
this to an u16 (unisigned short). That helped not getting a negative number here.

Code: Select all

if (data.header.length - data.read != vertexBufferByteSize)
	{
		os::Printer::log("Invalid size of vertices found in 3ds file.", ELL_WARNING);
//		return;
	}

I've commented out the return. Since this is an exported .3ds mesh from 3ds max 6 I have no idea what's wrong about it. It loads fine after removing the return (perhaps just a warning?).

Yes, I have the same problem when I try to load a very complex model with lots of vertices and faces.
