Question of grey level

[Frenchy Pilou]

Can I transform in Zbrush a color image in grey level image ?
I don't realised that with the Render/ Ajustment :confused:
Any idea ?

If i understand the question.............yes you can turn a ZB image into a grayscale image within Zbrush. One way would be to export the final image then re-import it back into ZBrush as a new texture. Then create a new layer. Choose the Flat material and fill the layer with the imported image texture. Then choose the Saturation brush. Select a large size (128), set DRAW to RGB only at 100. Then paint across the image while holding the ALT key. This will Desaturate the image turning it into a grayscale image.

Another approach is to import the image back in as a texture, press Texture>MakeAlpha to turn it into an alpha (and therefore, grayscale). Then you can export it from there or press Alpha>Make Tx to turn it back into a texture -- but grayscale rather than the original color.

The 2 methods work fine and make the same result !

A little dark than my programm of Post Production see below ! But it's nothing because I can now lighting with the Render/Adjustment :)
All is now possible in Zbrush :)

Method of Aurick is tricky !
Method of Menta is more explorative for the functions and keys :)
But for the 2 methods don't forget to put this damned "AutoCrop" on Off for making the texture !
Else you don't crop the entire image !
Thx both for the trick :cool:
