MRGBZ - problem

ZBrush Usage Questions
#1

Hi everybody

I created very bumpy skin patch with detailed texture (lets say dragon skin)
the idea was to grabDoc alpha and texture and then dragRec it all along surface
(this is where i realized theres specialized tool for this - mrgbz grabber)

problem is that zbrush is using “alpha” slot for brush in general (not just for zadd or rgb)
so when i apply my new brush, alpha afects RGB info also , so i get my texture masked by alpha
(this makes mrgbz grabber very useless imho)

idealy there should be separate alpha channels for zadd and rgb …

my question is if theres any workaround for this in zb?

yeah, but you’re not going to like it.

make a stroke with with the alpha you want to apply.
turn off the alpha, turn on the texture, replay last stroke (1)

Make sure you don’t do anything else between this or it will repeat that action rather than the stroke.
You can probably set up a macro for this as well.

#3

actually i like it, very good way around

only thing to mention is to do texture first cause if you sculpt first u may mess up orientation of initial points and repeated stroke might not behave as original even tho it is “same”

nice one, ty
