not show *.x animaton

[Moore]

I did animation and export to *.x file. I compile project, but nothing happen. I see only background. When i display normal model without animation all's ok. So why i don't see my model?
This is code(may help):

Code: Select all

#include <irrlicht.h>

using namespace irr;
using namespace core;
using namespace scene;
using namespace video;

int main()

{ 
  IrrlichtDevice* device = createDevice( EDT_OPENGL, core::dimension2d<s32>(640, 480),
  32, false, true, false, 0);

  video::IVideoDriver* video = device->getVideoDriver();
  scene::ISceneManager* menage= device->getSceneManager();
  scene::ICameraSceneNode *kam = menage->addCameraSceneNodeFPS();
  device ->getCursorControl()->setVisible(true);
  kam ->setPosition(core::vector3df(0,0,-100));
  //Zasięg pola widzenia kamery
  kam ->setFarValue(90000);
  //Wczytywanie modelu
 IAnimatedMesh* mesh = menage->getMesh("anim.x");
 IAnimatedMeshSceneNode* pud = menage->addAnimatedMeshSceneNode( mesh );
  pud -> setScale (core::vector3df(-300,-300,-300));
  pud -> setPosition (core::vector3df(0,0,900));
  pud ->setMaterialFlag(video::EMF_LIGHTING, false);
  pud ->setMaterialFlag(video::EMF_BACK_FACE_CULLING, false);
	   pud->setFrameLoop(0, 14); 
pud->setAnimationSpeed(15);



int lastFPS = -1;

  while(device->run())

  {
    video->beginScene(true, true, video::SColor(255,113,113,133));
    menage->drawAll();
    video->endScene();
    
int fps = video->getFPS();
		if (lastFPS != fps)
		{
			wchar_t tmp[1024];
			swprintf(tmp, 1024, L"Movement Example - Irrlicht Engine [%s] fps:%d", 
				video->getName(), fps);

			device->setWindowCaption(tmp);
			lastFPS = fps;
		}
    
  }
  device->drop();
  return 0;
}

Wrong path for your model probably. What does it say in the console window?

[CuteAlien]

Try if it works in the meshviewer. If it works there it's probably a path problem. If it does not work there please check if it works in the directx viewer for comparison.

[Moore]

I tried with meshviewer and it doesn't work.

Well, console wrote something like this:

Code: Select all

Index count per face not equal to face material index count in x file.
Mesh without material found in x file.
Loaded mesh: anim.x

I also tried with 3D Object Viewer and then a have that error:

Code: Select all

Runtime error 7018- Could not load 3D object at line 525

Help anyone?

Hi,

which program did u use to create the modell?

Which exporter did u use to export to .x file?

Maybe you could send me the modell .x file via pm and i ll check it.

I use Blender 2.48, defalut exporter which is in blender. A model is there: http://www.wrzucaj.com/292624

[Acki]

having a short look at the mesh datas it seems the problem is that the exporter creates quads instead of triangles !!!

if you look at the indices you see this (line 5821):

Code: Select all

1440;
4; 0, 3, 2, 1;,
4; 4, 7, 6, 5;,
4; 8, 11, 10, 9;,
4; 12, 15, 14, 13;,
4; 16, 19, 18, 17;,
4; 20, 23, 22, 21;,
4; 24, 27, 26, 25;,
...

it uses 4 indices per face (= quad) !!!

but it should be like this:

Code: Select all

4512;
3;0,1,2;,
3;3,1,0;,
3;3,4,1;,
3;4,5,1;,
3;1,5,6;,
3;7,0,2;,
...

3 indices per face (= triangle) !!!

well, I don't use Blender, but maybe there is a setting for the exporter so it creates tris instead of quads !?!?!

[hybrid]

Irrlicht should cope automatically with the quad/triangle conversion. I'll check this later.

allright, so this seems not to be the problem...
I tried to load the mesh into the mesh viewer and it can load it, but it doesn't load animations and the mesh is corrupted:

[Moore]

May, it will better to use another format. What is good for animations?
Btw. what format is good for maps?

[Adler1337]

What is good for animations?

[Moore]

I tried to load my animation in DeleD. All (without animation, and "some" smoth was ok). Even it had color, i gave in blender. So why irrlicht refuses to obey ;]?

Btw. I have irrlicht 1.3

MS3D also doesn't load the mesh...
Irrlicht (1.7.1) at least tries to load it, even it's corrupted then (see screenshot above) !!!

[hybrid]

Since the Microsoft MView refuses to load the mesh,, we won't work on this for any reason. Try a different mesh format.
