Mesh LOD

Hi, I'm having some trouble with exporting LODs for objects.

1. It seems that I have to leave Export LOD option in the Export dialog deselected to really export LODs.

2. I use my 'display units' setting in max set to Metric (Meters). How large are the units used by the LOD distance list? It would be actually nice if it used the same display settings as max.

3. I don't really know what those values in Object properties mean. Say I want an object at 10m to be 50% of the original, and at 20m 10% of the original. How do I set it up?

4. If I select a bunch of objects, and set their LOD settings everything works fine. But if I close the Object properties window and open it again, with the same objects selected, I can't mass edit the properties anymore.

Thank you

I have confirmed there is an issue with the "Export LOD" option of the export dialog, thanks for reporting, it has been fixed and will be in the next update

The lod system uses the current max units as the same in ogre units

The values of the Lod options are, the "Reduction Value" and the "Distance List"

The reduction value is the percent applied to each lod level in relation to its previous level, i.e. in a mesh object with 10000 polygons, with a reduction value of 50(%), and a distance list of 800, 2000 and 10000, the resutling lod levels are

the first lod level is the full resolution (100%, 10000 polygons)
the next lod level is the model at half resolution (50%, 5000 polygons) when the object is at 800 units distance from the camera
the next lod level is the model at half resolution of the previous level (50%, 2500 polygons) when the object is at 2000 units distance from the camera
the next lod level is the model at half resolution of the previous level (50%, 1250 polygons) when the object is at 10000 units distance from the camera

That cleared a lot, cheers!
