Hello,
I have a material. I always have to warm it up with red.
How can I save this material with the new color? I have tried many ways and searched the forum and tutorials with no luck.
I am using zbrush 3.12/mac. Here is the material with the added red that I want to save out. Thanks in advance.
you can either modify the matcap by adding the red to it and saving it as a new matcap or apply the colour to the subtool permanantly 
man i wish i could remember how i did this… i know it was kinda sorta tricky, but i did get it to work and this is just one way of doing it, and is actually kind of overkill. if you notice in a matcap, some have a “material A” and others have “material A + B”. Both of these are simple textures that are created when you make a matcap with the editor and can be modified with their native tools in the editor. Well what if you wanted to change the hue of a matcap because you love the settings but don’t like the color. If you do it this way, you can end up making a basic white material with the same settings as toxipapawax for instance and make it any color you want. So, with that being said, the texture samples light and color simultaneously, and when you are creating a matcap, you can load a texture to be used as a shading sample. again, i can’t remember how i did this, and i would have to mess around with it again to make it work and i am at work on my lunch and can’t help you right now. you need to get the texture samples used out of toxicpapawax, save them as whatever, open in photoshop, and in your instance, ad a bit of red curve to it or something, load it again, and save it as a different material. i dunno… it sounds ass backwards, but matcaps are baked materials because they are based on those shading texture samples. if you modify the sample externally and load/save a new material with those you’ll have the desired result i think. mess around with it and i think you can figure it out. cheers!
You can do several things but the easiest might be to go into Material>modifiers and change color swatch A to the tint you want, then resave as a new material.
The other way would be to make a new source image for the material by displaying the original material warmed up as you’ve shown on a sphere (subdivided a few times for smoothness), then select the MRGBZGrabber tool and capture the sphere as a texture (by default it will close-crop up to the edges of the sphere). Under Material>modifiers, replace the original image with the new texture and resave as a new material.
