Hi, the texture in the box of oranges scene is sonehow flipped from right to
left. I want to fix this but do not know how. Can anybody give me a hint how to
flip the logo image_map texture?

#declare m_madera_cajon=
material{
  texture{
    pigment{
      image_map{jpeg "flat_wood_4022164.JPG" interpolate 2}
    }
    normal{
      bump_map{jpeg "flat_wood_4022164.JPG" bump_size 1}
    }
    rotate 90*z
    scale .5
  }
  texture{
    pigment{
      image_map{png "logo" interpolate 2}
    }
  }
}

negatively scaling a given axis can often do the trick, eg '<-1,1,1>' to flip X,
unsure about your situation.

I tried scale <-1,1,1>, and scale <1,-1,1> and scale <1,1,-1>, but that did not
work.

Maybe I need to change the camera settings? - :

// Include file generated by Bullet Physics Playground
// 2026-06-23 19:33:14 by koppi
#declare use_focal_blur = 0; // 0=off 1=low quality 10=high quality

camera {
  location < -47.0793, 40.3916, -2.00584 >
  right - image_width/image_height*x
  look_at <816111, -576540, 37955.3>   angle 66.2759
  sky <0.576982, 0.816757, 0.000449072>
#if(use_focal_blur)
  aperture 0
  blur_samples 10*use_focal_blur
  focal_point <0, 0, 0>   confidence 0.9+(use_focal_blur*0.0085)
  variance 1/(2000*use_focal_blur)
#end
}

I see 2 easy ways :
1) Change rotate 90*z for rotate -90*z
2) Change image_map{png "logo" interpolate 2} to image_map{png "logo" 
interpolate 2 scale <-1, 1, -1>}

This line flips the whole image :
right - image_width/image_height*x
Change to :
right image_width/image_height*x
