Disabling lighting seems like it may have fixed the problem. > Still playing. Yes! clouds now appears like they should : http://perso.wanadoo.fr/frbouvi/flightsim/fgfs-clouds3d-ok.png However, there are still problems : 1. I can't see clouds from the cockpit, (Well, not really, there are clouds in the cockpit : http://perso.wanadoo.fr/frbouvi/flightsim/fgfs-clouds3d-inboard.png or is it fire ?) 2. When I take a screenshot from the chase view, the plane model disappears, 3. The propeller disk is drawn with the wrong blend function : http://perso.wanadoo.fr/frbouvi/flightsim/fgfs-clouds3d-propeller.png (taken with win screen capture, otherwise there is no cockpit with F3) 4. I can see plain textures sometimes (often when in the cockpit) : http://perso.wanadoo.fr/frbouvi/flightsim/fgfs-clouds3d-texture.png Cheers, -Fred ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

The curious thing is that the 'coloring bug' and the the texture 'jitter' just appeared recently and I can't see what changed to cause it.

Also I never > had the 'text' texture Right now I'm wondering if it is related to the use of glColorMaterial()? I've never had that play nice with setting material colors explicitely (with lighting turned on.) I remember Steve Baker investigating the exact specification of what should happen when you switch between the two methods of specifying colors. His conclusion was that the spec was ill defined and not even his high placed contacts had a good answer. The cloud3d code appears to be using glColorMaterial() to set the color and I'm thinking that colors from the rest of FlightGear are bleeding over into the cloud code. i.e. when I enable the HUD I start getting dark green clouds. When I disable the HUD, the clouds start popping back to shades of gray. > FYI > I have to leave FGFS alone so I get some real work done > for a couple of days, mapserver stuff. > > But I am still reading mail :-) Not fair!

Re: [Flightgear-devel] 3d cloud rendering problems
I think you are on to something ! That would explain the lightening of the clouds with each pass. BUT this only started after I updated my code the other day !. Also I never had the 'text' texture FYI I have to leave FGFS alone so I get some real work done for a couple of days, mapserver stuff.

[Flightgear-devel] 3d cloud rendering problems
Norman, Here's something for you to play with. Based on my own experiments, I believe that the cloud rendering problem centers around not having the correct state setup when we draw the cloud imposters. So, I don't believe it's an issue of protecting state around a particular section of code, I believe it's an issue of getting the state setup correctly before calling the imposter rendering Update() code. I'm wondering if it is related to the correct glColorMaterial() glEnable(GL_COLOR_MATERIAL) glColor() calls, because I'm seeing clouds with different colors, including but not limited to black. The imposter generation code could be inheriting whatever color was left over from the last thing we drew.
