I have this .scene file here (deleted the other omni nodes, otherwise the page will get huge) and everything works perfect. Only one thing doesn't work: the lights.

I guess the omninodes aren't specified by the exporter the right way to be used in DotSceneOctree.

Example:
My own .scene file and one from the tutorial, which works.

Tutorial omni node:

Code: Select all

 <node name="Omni01" id="5">
            <position x="-23" y="49" z="18" />
            <rotation qx="0" qy="0" qz="0" qw="1" />
            <scale x="1" y="1" z="1" />
            <light name="Omni01" type="point" intensity="0.01" contrast="0">
                <colour_diffuse r="0.4" g="0.4" b="0.5" />
                <colourSpecular r="0.5" g="0.5" b="0.5" />
            </light>
        </node>
My omni node:

Code: Select all

        <node name="Omni01" id="5">
            <position x="-0.903894" y="0.894635" z="0.286612" />
            <rotation qx="0.0" qy="0.0" qz="0.0" qw="1.0" />
            <scale x="1.0" y="1.0" z="1.0" />
            <light name="Omni01" id="6" type="point" visible="true">
                <position x="0.0" y="0.0" z="0.0" />
                <colour_diffuse r="1.0" g="1.0" b="1.0" />
                <colour_specular r="1.0" g="1.0" b="1.0" />
                <light_attenuation range="0.2" constant="1.0" linear="0.0" quadratic="0.0" />
            </light>
        </node>
---------------

so... what's wrong with the node from the exporter?

All the sttributes with underscores have been renamed in the new .scene format. ie. diffuse_colour is no diffuseColour. The same applies to all attributes, no longer do any of them have underscores.

For a complete listing of each element, and attributes, look at ogreaddons/dotsceneformat

so that would make it:

meshfile --> meshFile
colour_diffuse --> colourDiffuse
colour_specular --> colourSpecular
light_attenuation --> lightAttenuation

For an update: The lights were showing up... Just, the attenuation values were not read in by the demo dot scene app.

I updated the load light routines in the demo to parse the lights for every possible param. ;)
