Hi All !
Config : Ogre 1.6 and NxOgre 1.0 R21
First, wonderful work for this NxOgre !!
So, i have got a problem with TriangleMesh :
Ogre::Entity* mSol = mSceneMgr->createEntity("Ground", "nx.floor.mesh");
mSol->setCastShadows(true);
TriangleMesh *mesh = new TriangleMesh("nx.floor.mesh");
mScene->createBody("Ground", mesh, Vector3(0, 0, 0),"model: Ground, model-type: reference", "static: yes");
This makes the app crashing.
Whereas with :
mScene->createBody("Ground2", new NxOgre::Cube(500,10,500),Vector3(0,-5,0),"","static:yes");
;
It works fine.
Is there some known issues with triangle mesh and .mesh ?
I just want to load a .mesh and made it static.
Thank you very much in advance !!

You have to convert it into a nxs using flour.

I convert my cube using :
flour convert in:cube.mesh, into :triangle, out :test.nxs
I copy my NXS to the root of my c:
And then add to my App:
Ogre::Entity* mSol = mSceneMgr->createEntity("Ground", "nx.floor.mesh");
mSol->setCastShadows(true);
TriangleMesh *mesh = new TriangleMesh("c:/test.nxs");
mScene->createBody("Ground", mesh, Vector3(0, 0, 0),"model: Ground, model-type: reference", "static: yes");
Still crashing...
My mesh is not null but seems not be well instantiated...
Thank you for your help BetaJaen

Your nearly there. You have to load it in through the resource system; give it a name, and give triangle mesh the name.

NxOgre::Resources::ResourceSystem::getSingleton()->addMeshAs("file://c:/test.nxs","TryNXS");
NxOgre::TriangleMesh* mTriangleShape = new NxOgre::TriangleMesh("TryNXS");
mScene->createBody("BodyNXS", mTriangleShape , Ogre::Vector3(0, 0, 0), "","static:yes");
Crash
I need more advices BetaJaen lool
and if you have an exemple that would be great...

Try with your sample code :
NxOgre::Resources::ManualMesh* cube_test = new Resources::ManualMesh(Resources::MT_Triangle);
cube_test->begin();
const float size = 2;
cube_test->vertex(-size,size,-size); //0 position
cube_test->vertex(size,size,-size); //1 position
cube_test->vertex(size,-size,-size); //2 position
cube_test->vertex(-size,-size,-size); //3 position
cube_test->vertex(-size,size,size); //4 position
cube_test->vertex(size,size,size); //5 position
cube_test->vertex(size,-size,size); //6 position
cube_test->vertex(-size,-size,size); //7 position
cube_test->triangle(0, 2, 3);
cube_test->triangle(0, 1, 2);
cube_test->triangle(1, 6, 2);
cube_test->triangle(1, 5, 6);
cube_test->triangle(4, 6, 5);
cube_test->triangle(4, 7, 6);
cube_test->triangle(0, 7, 4);
cube_test->triangle(0, 3, 7);
cube_test->triangle(0, 5, 1);
cube_test->triangle(0, 4, 5);
cube_test->triangle(2, 7, 3);
cube_test->triangle(2, 6, 7);
NxOgre::Resources::Mesh* mesh = cube_test->end();
mesh->save("file://cube.nxs");
Resources::ResourceSystem::getSingleton()->addMeshAs("file://cube.nxs", "Cube");
mScene->createActor("Cube Test", new TriangleMesh("Cube"), Vector3(0, 1, 0), "static: yes");
Still crashing on create actor...
Are you sure that TriangleMesh isstable with 1.0 R21 ??

You did apply the patches to fix the mesh system right?

I Add this line in zero() of MeshData (NxOgreMEsh.cpp):
mMaterialAlias = 0;
and the two
mMesh.zero() in constructors
NxOgre::Resources::ResourceSystem::getSingleton()->addMeshAs("file://test.nxs","TryNXS");
NxOgre::TriangleMesh* mTriangleShape = new NxOgre::TriangleMesh("TryNXS");
mScene->createBody("BodyNXS", mTriangleShape , Ogre::Vector3(0, 0, 0), "","static:yes");
Still crashing on
mShapeDescription.meshData = mMesh->mMesh.mTriangleMesh;
Very annoying...

Just upgrade to T5 then. It's much better and doesn't have the bug.

Ok i found something very strange to make it work
NxOgre::Resources::ResourceSystem::getSingleton()->addMesh("file://test.nxs");
mScene->createBody("test.nxs",new TriangleMesh(NxOgre::Resources::ResourceSystem::getSingleton()->getMesh("test.nxs")),Vector3(0,0,0),"static:yes");
I use this code. Put my test.nxs at the exe root. And put test.mesh -> rename in test.nxs in media/models folder to make it work !!
I am going to make some more investigation...
[EDIT] Confirm the "trick", works perfectly ! Thank you for your help !!

You had test.nxs in a media folder all this time? You do know that NxOgre doesn't use the Ogre's resource system? Everything has to be specified in absolute or relative paths.
Rom1FromMars

Yes. I know that. As i said i put the test.nxs in root of my Exe.
But for visual (Ogre) i have to put test.mesh in media/models and rename it to test.nxs to make it work.

use this:
NxOgre::Resources::ResourceSystem::getSingleton()->addMeshAs("file://../../media/models/test.nxs", "test.nxs");
You may have to add or remove some of the ../ in order to get it right, basically use 1 ../ for every level up the chain from your working directory. For example, I use:
/
/media/models
/Bin/Release
/Bin/Debug
So, I use
file://../../
to get from Release (or Debug) back to
/
then media/models to get to the directory I want.
