There's another trick than can be used to make it invisible - know the RGB color of the object then have a panel of that color on top. It's not easy to find the color due to it being transparent, but, given that I have the formulas for calculating transparency, I could do that.
I'll need at least 2 screenshots though, 3 is preferred for enhanced accuracy:
1. A black (0, 0, 0) panel beneath it (no overlay)
2. A white (255, 255, 255) panel beneath it
3. (optional - for enhanced accuracy), a gray (128, 128, 128) panel beneath it
From there, I can identify the color to ±1 color unit. Don't use JPG as JPG destroys the image. Use PNG or ZIP up the BMP files and upload the ZIP file.
