Mince !
Bon, j'ai une autre piste : Le shader est peut-être modifiable pour l'empécher de tourner de 90° ?
Je poste le code ici, on sait jamais si quelque chose tape dans l'oeil d'un codeur :
mirror.glslp :
shaders = "1"
shader0 = "shaders_glsl/mirror/c**ktail_mirror.glsl"
filter_linear0 = "false"
wrap_mode0 = "clamp_to_border"
mipmap_input0 = "false"
alias0 = ""
float_framebuffer0 = "false"
srgb_framebuffer0 = "false"
parameters = "height;width;location_y;location_x;ZOOM"
height = "-1.145000"
width = "1.750000"
location_y = "0.800000"
location_x = "-0.500000"
ZOOM = "1.000000"
c**ktail_mirror.glsl :
#pragma parameter height "Image Height" -1.145 -6.0 6.0 0.01
#pragma parameter width "Image Width" 2.0 0.0 10.0 0.05
