Steve,
Thanks for solving this problem with my model. After testing with one of the SOH members I had suspected that it was in the Alpha Testing but was not sure until now. I do not have missing glass when running DX10 Preview so I had no problem to fix.
I model for FSX as a hobby (freeware only) and have picked up most of my knowledge from the experts at FSDeveloper and I can't say enough about how supportive and instructional these people are. Although I have never encountered the problem there is some sort of visibility problem with glass gauges as seen through the cockpit glass so I followed recommendations which I most probably didn't set correctly.
In my FSXMaterial for the glass I have the following set;
Z-Test Alpha
Alpha Test Level set at 0.0 (which doesn't make sense now that you mentioned it)
Alpha Test Mode: Always
Set final alpha value at render time
Final Alpha Multiply: 1.0
Z-Write Alpha
I'm going to eliminate this section of the material for my next release unless you can suggest a change in the settings.
I would like to purchase your DX10 Fixer but my next SS check is going towards purchasing Prepar3D, which I have wanted for quite a while, so it will have to wait for a couple of months.
Thank you
Paul "Mechanic" Domingue
