In my local copy I've enlarged it some and made the bezels a little tighter. It's interesting that texturing the layers helps with the geometry. Also one thing that plib does support is the emmissive property and I'm getting a readible instrument that looks reasonable by applying a very small amount of white. It still doesn't solve the lighting issue, of course. By tomorrow night I should have finished detailing the AI.

It occurs to me that I might be fooled by the tiny size of the A-4 panel into thinking it's larger than it is. The current model is actually only 7cm/2.75" in diameter, though, which is almost certainly too small. Or maybe there's a scaling factor coming in from somewhere else? I looked at the aircraft model in AC3D and decided that the units were in meters, but maybe something else is applying scaling? Andy -- Andrew J.

Just checked in a start on some adjustments to the cockpit geometry and a bezel for the attitude ball. How sure are you that the ball is supposed to be 6" in diameter? It "looks" to be about 4" in every picture I've seen (but those can be deceptive).

Yeah, I can do that. :) I squished them into a single 256x256 texture, though. There a loss of 33% resolution in only one direction, which isn't so bad. A 512x512 texture takes a whole megabyte of card memory, which is asking an awful lot for a single instrument, no matter how important it is. The seams are gone, and it looks better, although the lighting issues and jitter are still to be fixed. Thanks, Andy -- Andrew J.

You can combine all six 128x128 textures into a single 512x512 attitude.rgb file. I think that autoscaling in plib is working now, so old Voodoo3 cards will automatically get a scaled-down version; at least, I'm using 512x512 textures for my aircraft models, and no one is complaining.

Unless I've misunderstood the file format, this won't work. You only get one texture per object; so I need at least 6 objects. Andy -- Andrew J.
