load error bitmap or wrong gamma ?
(1/1)
Gionni:
hi all, i have a problem.
i have no match when i load a map compared.
In this example to verify that everything is correct I created a map from photoshop but there is no match. The color in photoshop is a 128 gray but corona color does not report the same color.
Input values is not checked
Thanks everyone for the help
maru:
So you created a bitmap in Photoshop which is covered in RGB 128 gray, and you also created a Corona Color node with RGB 128 gray, but they do not match?
What happens if you enable the "input values are in linear color space" option in the Corona Color?
romullus:
Make sure that you've load the bitmap with overridden gamma 1.0 and not automatic gamma.

Enabling the "input values are in linear color space" the color increase the lighting. But t he problem not is the Corona Color, that is ok, but the Birmap or Corona Bitmap that is not the same of the texture and the corona colour.
If I load the texture with the gamma 1.7, the resutl is similar to Corona Colore one
