FS9 Materials-Color/Transparecy

This is a combination of posts I made at flightsim.com and thought I'd enhance my chances of a reply here.Most of my FS9 to FSX ports have been very successful. The Alpha channel trick has worked for every one that has a texture for the glass, and/or prop disks depending on the problem.I haven't made any attempts at designing models since FS98 so I didn't know what FS9 and FSX use for window transparency other than textures. I have an FS9 plane that has the "Glass Opaque Reflection" problem in the VC. It doesn't have a texture, that I can reset the alpha on, to make it work in FSX(I tried em all).A little background for my questions: I had taken some old FS98 Static aircraft, buildings, etc that I had created as APIs, tweaked the scasms, and used ModelConverterX, to not just convert them and assign the proper textures, but tweak colors in the materials dialog.(saved hunting all those polys down in scasm)Then I came across MDLMat.exe and the FSX version MDLMatXX.exe and started thinking about airplane models using Materials.The planes that do not have a texture for the glass, I'm thinking, get their color and alpha from a "Material".If so, and the FS9 plane's glass is a material instead of a texture it can be changed to FSX values and the fix would be in, so to speak.In MDLMat.exe the "Modes" available are Diffuse, Ambient, Specular, and Emmissive. Greek to me!There is also a Numerical Specularity entry available.I don't know how, or even if, the mode and value are entered into the model's source.Thus the questions;1-Which Mode is proper?2-What Color range should I expect to see in the FS9 material for the Glass?3-What Alpha range should I expect to see in the FS9 material for the Glass?4-Is the Alpha Channel or Color the only change necessary when editing the materials?5-What Color and/or Alpha should I use for the most Glass transparency in a material for FSX?I know Black 0,0,0 is transparent for the 2D, 1,1,1 for masks and I generally use 20,20,20 for the alpha in DXTbmp to fix textures for ports.According to MDLMat there are 42 Color Materials in the model to choose from.I have created 42 different .mdls by copy/paste/rename the original.Unfortunately there aren't a lot of unmistakeable colors to help narrow it down.With 42 materials, R,G,B, and Alpha on each material the iterations are numerically challenging. I'm hoping one of you design Gurus can help me trim the list!I'm simply exploring options to salvage otherwise excellent planes for use in FSX.Gauges, Panels, Aircraft.cfg and .air haven't really changed much, so my years of tinkering with those have paid off.Is this method of a plane's salvation valid, or a pipe dream? Thanks...Don
