LOD not visible

[Anthea]

I like to use LOD for my project. I tried as [url =http://www.ogre3d.org/tikiwiki/MeshLod]wiki[/url] said but I can't see any visual change so far.

First of all I needed to upgrade my SDK and all my meshes to 1.10. I upgraded my meshes with the option -l -3 with a positive output.



Here is my code so far:

Code: Select all

	Ogre::MeshPtr meshPtr = Ogre::MeshManager::getSingleton().load(mesh, Ogre::ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME);
	Ogre::LodConfig config(meshPtr);
	config.createGeneratedLodLevel(5, 0.5); // At 5 ogre worldspace units use 50% reduced mesh
	config.createGeneratedLodLevel(10, 0.75); // By default, it is using DistanceLodStrategy and proportional reduction.
	config.createGeneratedLodLevel(15, 0.9); 

	config.advanced.useBackgroundQueue = true; // Generate in background thread, later inject with framelistener.
	Ogre::MeshLodGenerator::getSingleton().generateLodLevels(config);

	mEntity = mSceneMgr->createEntity(mName, config.mesh);

Isn't MeshUpgrader generating basic LOD's for me? How do I access the generated LOD's?

Another point: I am doing this for every object in my scene also if they have the same mesh. What is best practise at this point? Create one MeshPtr and use it for serveral Entities or create for every entity an own meshPtr. Does it even make a difference?

I think you also need to set-up the lod strategy in scene manager or something.

Hello, I am having the same problem, but I am using a manual mesh. I didn't find how to set up any strategy. I think the wiki should mention that part

Thanks

There's a lod stategy manager. If you get the default strategy you will get some kind of a distance strategy. From there you should be able to modify the individual lod levels and have Ogre do the switching for you.
