ogl-es COgreMeshFileLoader bug

[penguin03]

I use EasyOgre exporter to export a mesh with skeleton animation from 3ds max, Use irrlicht to load and render it, and it's wrong. I use OgreMeshViewer to open it, it's correct.

The hand and foot is not correct, I use the latest ogl-es branch r4525

Here is the screenshot:



Here is the ogre mesh:

Here is the code:

Code: Select all

 
IAnimatedMesh* mesh = dev->getSceneManager()->getMesh("girlgirl.mesh");
 IAnimatedMeshSceneNode* node = dev->getSceneManager()->addAnimatedMeshSceneNode(mesh);
 node->setMaterialFlag(EMF_LIGHTING, false);
 node->setRotation(vector3df(0, 180, 0));
 node->setScale(vector3df(0.5, 0.5, 0.5));
 node->setMaterialTexture(0, dev->getVideoDriver()->getTexture("UVgirl.png"));

I think you have to ensure that the base pose has no animation, that is, all bones have the identity transformation.

[penguin03]

Do you mean at the animation frame 0, all bones have no transform? Now we have transforms at frame 0, but ogre mesh viewer is ok

[mongoose7]

Then I guess the OGRE mesh viewer is better than Irrlicht?

@ mongoose7

I just tried as you said, at the first frame, there is no transform. The result is: only the first frame is correct, the rest is same.

Any other suggestion?

Did you have the same effect in trunk? Please check a model in Irrlicht mesh viewer.

@Nadro

Just try it with mesh viewer under trunk, same effect. The hand and foot are not correct. Maybe the 3ds max biped bones affect it?

I just tried as you said, at the first frame, there is no transform. The result is: only the first frame is correct, the rest is same.

Any other suggestion?

Just to be sure, the starting pose has no transformations and the subsequent poses have transformations *relative* to the starting pose? That is, all the bone transformations have been multiplied by the inverse of the original transformation for that bone?

@mongoose7

I'm not sure the pose transforms are fitted for Irrlicht engine. I use EasyOgreMax exporter to export the mesh and animation from 3ds max 2012.

I'm confusing the Ogre3d engine use the same method to calculate the skin animation with Irrlicht?

[mongoose7]

No.
