The material editor allows you to brighten and invert texture images such as bump maps.
When you brighten the map you loose the contrast in the map. It would be great to have another control like levels, curves, contrast, saturation etc. I find myself having to open the bump maps a lot in Photoshop to lighten them or add contrast and create another jpg file. Having the adjust-ability in Enscape would save time and the number of files in my system.
Thank you
