addOctreeSceneNode dosen't work

[Stefan]

addOctreeSceneNode dosen't seem to work anymore.

Code: Select all

mesh = smgr->getMesh(file); // mesh is loaded correctly
sceneNode = smgr->addOctreeSceneNode(mesh);  // returns NULL

At revision 1145, example 02.Quake3Map works for me.

Code: Select all

	scene::IAnimatedMesh* mesh = smgr->getMesh("20kdm2.bsp");
	scene::ISceneNode* node = 0;
	
	if (mesh)
		node = smgr->addOctTreeSceneNode(mesh->getMesh(0), 0, -1, 128);

Does it work for you?

[Stefan]

this example works...
however, if I use

Code: Select all

node = smgr->addOctTreeSceneNode(mesh, 0, -1, 128); 

instead of

Code: Select all

node = smgr->addOctTreeSceneNode(mesh->getMesh(0) , 0, -1, 128); 

it dosen't work for my .x model.
With "20kdm2.bsp" it still works...

btw, the mesh returned by mesh->getMesh(0) seems to be wrong with some meshes.

There's definitely some funky stuff going on in there but I'm hesitant to post a bug report. For instance, I in particular have to do myAMesh->getMesh(0) on a certain .x file I have for it to be in the right orientation. Just don't have the energy to write up a bug report right now though and I don't even know if it's Irrlicht or Blender for that matter. I was told long ago to use AnimatedMeshes for everything in any case.

Since addOctTreeSceneNode(IAnimatedMesh* mesh, ...) just calls addOctTreeSceneNode(IMesh* mesh, ...) using mesh->getMesh(0), I find that a little hard to understand.

KHAAAAAAAAAAAAAAN!

Er, I mean: LUUUUUUUUUUUUKE!

[kornwaretm]

same problem

[bitplane]

I'm guessing this is the known bug with SkinnedMesh, please post your mesh to be sure. There needs to be two ways of loading a B3d/X/MS3D mesh that doesn't contain animation data.
Either-
a) You want to treat it like an animated mesh and move its bones around (ie ragdoll)
b) You want it completely static and to ignore all bones (ie level)

[Luke]

yeah this is a hard one

I'll look into it, thanks for the link rogerborg

for now, can you try the quick fix: (let me know if it doesn't work, it hasn't been tested and it is 4am...)

Code: Select all

void FixStatic(IAnimatedMesh *Mesh)
{
	if (Mesh->getMeshType()!=EAMT_SKINNED)
		return;

	for (u32 n=0;n<Mesh->getMeshBufferCount();++n)
	{
		SSkinMeshBuffer *Buffer=(SSkinMeshBuffer*) Mesh->getMeshBuffer(n);

		for (u32 i=0;i<Buffer->getVertexCount();++i)
		{
			Buffer->Transformation.transformVect(Buffer->getVertex(i)->Pos);
		}

		Buffer->Transformation.makeIdentity();
	}
}

As I understand this code doesn't rotate vertex normals. Am I right ?

[bitplane]

Ah yes, you'll need to add rotateVect(Buffer->getVertex(i)->Normal)

[Chmel_Tolstiy]

Ah yes, you'll need to add rotateVect(Buffer->getVertex(i)->Normal)

now it's ok. thanks.
