    Is there a way to do "render scaling" in Ogre? I.e. I want Ogre to render the scene in 1080p resolution but I want the final output to the monitor be upscaled to 4K.

    this is trivial to do with a render_quad compositor

    Doesn't sound like it can be solved with simple render_quad compositor unless I'm missing something. If I understand correctly _createRenderWindow forces the resolution that Ogre uses for rendering the scene and no matter what value I give for target_width_scaled for the compositor, it will be scaled back to the size of the RenderWindow created.

        target scene

        }

        target_output
        {
            input none

            pass render_quad

    do you guys have any idea how can i make a SceneManager where i have images for heights/walk/water which ill use to generate the scene based on ?
    im still reading about octree

    @SNiLD
    TerrainSample in the sample browser does it like that
    siN
    @sindev95
    ok ill take a look
    ty
    @SNiLD can u gimme the path for the file ?
    siN
    @sindev95
    is it samples/simple/include/terrain.h ?
    SNiLD
    @SNiLD
    https://github.com/OGRECave/ogre/blob/master/Samples/EndlessWorld/include/EndlessWorld.h
    oh yeah that wasn't from image though, it generates random noise at: https://github.com/OGRECave/ogre/blob/master/Samples/EndlessWorld/src/PerlinNoiseTerrainGenerator.cpp
    but yeah instead of the noise you'd just read from the file
    siN
    @sindev95
    ill try to work around that
    cause there's a skybox
    grass
    tiles
    path
    water
    ..etc
    spawn points
    creatures
    i want to take these into account
    SNiLD
    @SNiLD
    can be done, Ogre::Terrain is surprisingly powerful
    siN
    @sindev95
    strange that there aint much resources about ogre3d
    the docs aren't good too
    i have to go around the samples and the core to understand everything
    SNiLD
    @SNiLD
    we use it in a simulation with 20km x 20km visibility to all direction with millions of trees, sea safety equipment, sea, city models, etc

    @sindev95
    what is the octreescenemanager
    SNiLD
    @SNiLD
    yeah, most stuff has to be done by reading the source code, although the documentation has improved a lot after paroj took over
    it reads in the class definition
    siN
    @sindev95
    would be much better if there's ytb tuts or more articles on it
    i mean the engien
    SNiLD
    @SNiLD
    we use the default scene manager as other really don't provide any improvement on open scenes

    @SNiLD what i did for now is

    @sercero
    Octree Scene manager was though as an optimization, but eventually it was found out that culling by brute force was best
    siN
    @sindev95
    create a SceneManagerCamera which is : public OctreeCamera
    and the SceneManager is : public OctreeSceneManager
    and play with'em
    SNiLD
    @SNiLD
    you should always create cameras, entities etc through the scenemanager
    siN
    @sindev95
    so you mean i shouldn't be using Octree at all in my own scenemanager
    or you mean i should add'em to it ?
