oh wow, this was completely unexpected!
Had about 8 different people/machines trying it before release and had no such issues reported,
but surely it's not so big test area.
But wait a minute - is that the compiled examples you downloaded on first page of this thread,
or was it the .mfa of the download which is finally available (good news!)
Since you posted a screenshot of the DLM city example, it's the latter, or both?
Any chance you didn't copy the P3D_ipm_p_r shader?
Seems like the issue appears to be with "repeating" textures, but it's very odd anyway.
But mmm, you also posted the clock tower example,
that I surely compiled and posted here, so it's probably not the cause.
Wondering if it's an hardware limitation.
Can you check your DirectX version?
(win key + r, then type "dxdiag")
Unlikely it's so old not to have support for ps 2.5 shaders though.
any chance you could try modifying the shaders (mainly the three "ipm" ones) this way:
float3 rs= float3(0.0-sp.x,100000.0, sp.y);
float3 rv= float3(sp.x, -100000.0,0.0- sp.y);
float3 rs= float3(0.0-sp.x,1000.0, sp.y);
float3 rv= float3(sp.x, -1000.0,0.0- sp.y);
and then inside the engine, CORE MODULE group, the big line 681:
set alt. value 46 to: 1.0 / AltValN( "P3D_engine", 40 ) * 1000.0
in case it's a floating point number size limitation...?
If nothing works, am I allowed to contact you privately in order to try understand what might be going on?
(with your time and availability of course)
