Hey, guys, for the record, and in addition to what Frosty has said, there are three PSP fields in CFS3 ETO Expansion 1.40, in the ACC_Airfields folder, in the ETO Expansion main game folder
1. ALG Bomber
2. ALG Fighter
3. ALG Transport
They only appear in Era 5, 1945. Two, A-2 and A-29, are listed in QC under France, and one, Y-29 is listed under Belgium.
I hope this helps.
I had a look at these airfields in ETO1.5 and did not find the PSP mat appearing even if the airfield .xdp calls for SurfaceType="steel_mats" .
There are several SurfaceType= called for dependind of the airfield: steel_mats,tarmac,grass,dirt,concrete,planks. but the runway folder only holds 2 textures dirt an concrete so I guess the other SurfaceTypes are missing from the game unless they are listed elswere.
I do have some unfinished Square Mesh Tracking texture files that I could send over, if you want.
Yes please Joost! I've managed to get some Sommerfeld tracking down but no decent screenies as yet, I'm still tinkering with the Z position to stop the flickering.
