Dora the Traveler and jigsaw puzzle game is another incredible game, which children favor. Swiper's spelling book game is figuring out how to get enough popularity like the Dora. I love to play casinos with interac with friends. There are a large group of children who play both Dora and Swiper game.

if you plug the XYZ vectors with parameters from -1 to 1 (which is the normals range) you can see how it converts to color. As expected, they influences RGB values respectively (X -> R, Y -> G, Z -> B), -1 to 0 and 1 to 255, leaving the other color parameters to neutral gray (128).

Any idea on how its converting the vector to and rgb value inside the Mesh colours component?  I tried using the deconstructed vector with fRGB and XYZ colour components but the values it returns are different.
