There are still some nice FS9 models that have been converted to be used in FSX. For quite a while they worked fine on my computer. But lately these older models all show the same problem. When I switch from 2D to VC, the view from the cockpit remains OK for a few seconds, then the cockpit window becomes light blue and non transparent.On some other forum someone indicated I needed to replace envmap.bmp in the ROOT/TEXTURE directory. That helped initially, on the ground anyway, but while flying the trouble started all over again. Now all the older models have light blue windows again.Since I had no problem for many months, something must have changed. Rather than re-installing FSX I would like to know what causes this problem. I would appreciate any suggestions.

Is it raining at the time? In that case, you'll need to install MS/ACES' "VC Rain" fix:Support Alert: Add-on Aircraft Cockpits Opaque in the Rainhttp://www.microsoft.com/Products/Games/FS...eintheRain.aspx

Thanks Bill. Yes the rain was the culprit!!I had changed the default start-up screen a while ago to an airport in the UK, and of course it had to rain there.I replaced the textures as indicated on the FSX support page.This is the second time you gave helped me out.regards,chris

This is the second time you gave helped me out.

That's why we're all here! I've long ago lost count of the number of times I've been helped here (and elsewhere)...
