Written September 22, 2015Nice. It's hard to find good "Sci-Fi panels" textures and I have a suggestion here: JPEG is especially bad for that kind of texture because some pixels color is slightly off in areas supposed to be made of the same color. These artifacts are hardly visible when you simply look at the bitmap. But when the texture is used for bump mapping, colors lack of precision makes the artifacts appears clearly and looks very bad. This is an inherent issue of a lossy format. That would not happen with a lossless format like PNG. Due to the nature of that kind of texture, the compression should be good enough. Could you update it with a PNG version? I hope you kept a lossless version somewhere...

Edited September 22, 2015In case you don't have a lossless version, I could manage to edit the texture in GIMP and to remove artifacts everywhere accuratly (using color selection tool with 15 threshold, picking color and refilling selection) then saved it as a grayscale PNG (RGB is overkill as all colors are shades of gray). The texture is now clean and accurate and the PNG compressed it to ~10 Ko instead of the ~156 Ko of the JPEG. This is a win-win! I can send it to you if you wish, don't hesitate to ask.
Looks great. Thanks for sharing.
