Not sure what I am doing wrong

Hi all,

I am trying to use the oFusion scenelib and am running into an issue.
I created a test model in 3d studio and it shows fine in the oFusion viewport.
When I try loading the OSM file into the project it doesn't appear.

in the application code I do the following according to the documentation.



void createScene()

{

OSMScene oScene;

oSceneCallback oe_Callback;



oScene.initialise( "test.osm", &oe_Callback );



oScene.createScene();



mSceneMgr = oScene.getSceneManager();

}

Any direction would be helpful. Thanks.

Did you put the .mesh and .materials in your resource path folders?

What is the ogre.log that your application/project creates, any hints there?

Create a camera in max from where you see your scene, then in your application set this camera as the current

Yup.
I have all the files exported in the resource path files.
Here is the scene in 3ds max

As for the log, this is what is logged for the oFusion

Can you post the osm file?

Try using more "suitable" power of two texture images (256, 512)

What is the result if you dont put the material file in the resource?

Implement an OnEntityCreated event to verify that the objects are loaded and use it to activate the "ShowAABB" to verify the node

Thanks for your help. I got it to work by removing



<sceneManager type="0" worldGeometry="terrain.cfg" />

The thing is, I selected that terrain.cfg in 3d studio as part of the world geometry. I no longer want to use it, but it keeps the information. Is there a way to clear it?

oFusion is a sweet product!!

you know, I still have a similar problem in our implementation. Not sure quite what is wrong but I did find a solution.

In our engine after calling the OSM sceneloader and loading a scene I would get a blak screen, however adding shadows manualy (I'm using stencil modulate) after the scene loaded, then everything displays correctly.

So try enabling the shadows in your app after loading the scene, see if that helps.

(BG colour doesn't work, but I'm using the skybox feature in OSM anyway)
