I am currently working on a JSBSIM fdm for a glider ( Centrair Pegase )

Is it really a normal map shading ? or something like bump map ?
I'm not sure what I am doing wrong, or if it is an issue in the shader
implementation.
Thank you for looking into it !

I have been inverting the red and green channels in gimp, now it looks
correct in any angle in FG.
Either I should see in blender if there is a way to directly bake it
like the FG shader expects it, or maybe the shader has a problem, and
the red and green channels should work in the other way.

There is also another approach to creating normal maps, using a
detailed, high polygon count model of the object, from which you
extract the normals and map them to the low polygon object which is used
in the game.

There is no (known) limit for the number of supported buttons or axes with
this implementation other than those of your operating system. On linux,
buttons, keys and axes are numbered by a 16bit unsigned integer which
limits your number of each to 65536.

i think that on my slow PC, your ridge lift is sometimes initialised a
little to early (while position is 0,0,0 maybe), resulting in some nan
in the result of terrain scan, wich lead to a nan in
/environment/ridge-lift-fps.
and as it's used to compute the next

line 238 :

lines 319-321 for desperate cases :
strength = lift_mps * SG_METER_TO_FEET ;
if(isnan(strength)) strength=0;
udpated the patch again, with another Nan killer from jano.
That seems to have worked for him, at least
