MD11MainBranch MD-11.3ds 0 -25 -0.5 CockpitMainBranch Aircraft/MD11/Models/cockpit/cockpit.xml ... CockpitMainBranch MD11MainBranch ... It doesn't work. The XML parsing failed and I got the stupid glider. =( I believe I have failed to understand your example. What did I do wrong?

Re: [Flightgear-devel] Some general questions
I meant, if in such XML file: MD-11.3ds 0 -25 -0.5 Aircraft/MD11/Models/cockpit/cockpit.xml ... How do I change the ordering of MD11.3ds and the mesh that was referenced in cockpit.xml?

Animation works on objects loaded in memory. When you add a submodel ( for instance, an instrument ) to your main model, it ends up as a branch of the main model. -Fred ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
Re: [Flightgear-devel] Some general questions
That example shows how to re-order the objects if they are in the same mesh file. What should I do if the objects that I want to re-order are in two different mesh files?

May be this have something to do with the fact that the opacity of my objects is 98%, but FlightGear seem to have trouble displaying multiple partially transparent objects that are overlapping one another. Yes, but that's really an OpenGL problem rather than a FlightGear problem. For example, if I have a plane with a transparent circle in the middile, and behind it is another plane with a transparent circle in the middle, you won't be able to see the second plane at all through the transparent portion in the first plane. (Semi) transparent objects should be sorted by distance from back to front. In some cases it is possible to determine the order beforehand In case of a HUD for example, it is best to define the canopy before the HUD because in the pilot seat every thing looks like it should be (yes knoe the F-16 has this problem right now) and from the outside few one barely would notice the difference. I believe Frederic has written an animation that does this automatically which is called alpha-test.

Re: [Flightgear-devel] Some general questions
I have found another thing that is quite interesting. May be this have something to do with the fact that the opacity of my objects is 98%, but FlightGear seem to have trouble displaying multiple partially transparent objects that are overlapping one another. For example, if I have a plane with a transparent circle in the middile, and behind it is another plane with a transparent circle in the middle, you won't be able to see the second plane at all through the transparent portion in the first plane.

This produces the side effect of being able to see through the aircraft -- not a lot, but it is noticeable if you look closely. Is this a bug or some sort in the 3ds module? I would expect so. Transparency can either be specified by the alpha color of the texture, or by the opacity of the vertex. There should be no need to specify both.

Re: [Flightgear-devel] Some general questions
I think I have found out why the transparency is not displaying properly. The transparency only show up when the opacity of the object is set below 99%. This produces the side effect of being able to see through the aircraft -- not a lot, but it is noticeable if you look closely. Is this a bug or some sort in the 3ds module?
