Further proof, using nodes - no matmatic tricks or handwaving.

Study this material. I have a tile node connected to the bump channel. Since I set the bump scale to 10, even the tiniest amount of variation is visible. So if we can see little squares, it means that the value in Tile_1 is different from the value in Tile_2.

The Tile_1 value is connected to a Color_Math:Divide node labelled "WHITE / 2". That node is dividing WHITE (255) by 2. So it is precisely half the maximum intensity.

The Tile_2 value is connected to a Simple_Color node labelled "GRAY 127".

My claim is that half the maximum brightness is not RGB 127,127,127. Look at the PoserSurface preview. Do you see the squares? That proves that 255 / 2 is not equal to 127.


Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
