Hello
I really appreciate to design instruments, for the moment I use the process above :
Model : Freecad (cad model) and blender (texture and export to ac3d)
Texture : gimp (thx to Helijah for his description of simples practices)
Figure : the dedicated image to specific instrument (graduation, numbers, green, yellow, red bars, etc...) : mathplotlib (svg exit)
The figures are svg files in order to be accurate in every scales (the not so accurate instruments are perfectibles i think)
Flightgear : xml files are created in the same time than svg figures
I got three questions :
1 - what can be the adequat texture resolution for flightgear (by now, i use 1024x1024 for no screen instruments, and 4096x4096 for big screens) ?
2 - which fonts should be used for dedicated era ('20s - '30s, WWII, '50s and '60s, '70s and '80s, first screens, now) and obvioulsy it depends to countries (alphabets in use)
3 - where can it be released for the flightgear users ?
