'Projecting Polypaint only' not working?

ZBrush Usage Questions
#1

Okay… So I have a ZTool consisting of two SubTools. One partially extracted through masking from the other. The original mesh has been polypainted. The extracted mesh has no polypaint information, but has a slightly different sculpt.
I now want to project the polypaint information over to the extracted mesh without altering it’s shape. Simple right? Select the target mesh, Turn off ‘Zadd’/‘Zsub’ and enable ‘RGB’, or ‘MRGB’ and hit 'Project All’.
Unfortunately this does not appear to work. While the colour information projects across as expected, so does the sculpt information… wether ‘Zadd/Zsub’ is on or off.

Am I missing something here?

That didn’t work the way you’re trying to do it in ZB4 , either. I honestly dont know if there’s a way to project Polypaint separate from displacment other than through Texture swapping. Im sure someone more knowledgeable will fill us in.

But for what you want to do, just store a morph target to your Target object first. Then Project the displacement and polypaint. Once projected, turn the Morph slider all the way up, and the displacement will be gone, but the Polypaint will remain.

Thank you Spyndel. Yeah, there’s always the Morph Target indeed.

I guess for now we’ll have to conclude that the standard way of projecting Polypaint data is officially broken.

#4

As I said, it has never worked that way, as far as I know. At least it didn’t in zb 4.

#5

i may be wrong but what about trying the zproject brush with rgb only?

#6

just been trying to do this with the Zproject brush myself … all I am getting is black atm :frowning:

#7

wow you’re not kidding, same here.

Unless they changed how it works, the Zproject brush seems not to work with color at present. Works fine with displacement.

In any event, it’s probably more work than just storing a morph target, anyway.

spyndel, i agree about the morph target of course, but doing a few quick tests using project all, the color isn’t transferring correctly at all, its block and missing parts, and this is off of a direct clone of the model so no change in deformation.
i recall recently seeing a tread about this but can’t find it at the moment.

Increase the Dist slider in increments in the Project All menu until you get good results. The default values frequently leave holes in the projection. Obviously you need both meshes at high enough resolution to both project and hold the detail and avoid blocky color.

I tested this and got fine results, after a couple tweaks.

Usually you would use Zproject for this. Rgb on and away you go with the subtool that requires texture being above the one that holds the texture. I used this function quite a lot in Z4, but unfortunately it seems to have a problem in the update, unless I am missing something.
