ZBrush Usage Questions
#1

Hi everyone,

I am a bit stuck and not sure if I am missing bits of the proceedure.:slight_smile:

I am attempting to project a high res version onto a retoped for animation low res model.

Here is what I have done:

loaded my high res version into zbrush (made in zbrush)

Appended my low res version (made in zbrush)

I pressed project all

(I read that u can use the morph brush and/or the zproject brush to move things back.)

Then I don’t know what I do next with the 2 meshes? Do i delete the high res version?

So sorry if this is a really silly question:)

Any guidance would be amazing. Many Thanks

It looks like you’re missing a couple of steps…assuming you are baking in Zbrush that is.

Once you append in your LP mesh and before you project you need to up the SubD levels until you get to a similar Polygon count of the HP mesh.

Store a MT.
Project all.
Clean up.

Again, this is only if you’re baking in Zbrush, if you are going to use another software to do the baking and you built your LP mesh to fit your HP mesh the way you want then you can by pass this step and just bake.

To answer your other question you can delete the HP mesh when you’re done or keep it as a subtool. It doesn’t really matter. But make sure you save a new version before you go and delete your final HP mesh.

Hi Beta-Chanel,
Thank you so much for your help. I will try that now.

By clean up- do you mean use the zproject brush or the morph brush-sorry I got a little confused .:slight_smile:

Thank you for the speedy reply x

Um , I just tried that lol and I still think I am going wrong some where.

As when I look at my lp mesh at its lowest level it still hasn’t changed? I think I am being a doofus. :slight_smile:

Load hp tool-append lp poly tool-subdivide lp up high enough to support the projection- store morph target…don’t laugh… store the morph target of the high or low poly?

Thanks for your help Beta Chanel :slight_smile:

#5

store the MT on the LP.

This is just to help you clean up projection errors.
What subD level are you projecting at? It should be at the highest.

Images always help as well.

Hi Beta Chanel,

Thank you for clarifying things for me -I will try it now.:slight_smile:

I was trying all sorts of combinations- to see if any of them worked -lol.
Yes I haven’t tried to post anything with an image yet- I really should, much easier then for people to see what is happening.:slight_smile: I will in future.:slight_smile:

Thank you again for the speedy reply:) I am off to test it out right now.

Feeling like such an idiot- Sorry Beta Chanel, can I just re trace my steps.

Load hp model
Load lp model
append lp model to the hp model
Sub div the lp model high enough.
Store morph target on the lp model at the higest sub div level

Go to the hp model- project all button

So the high details will project onto my low res mesh?

But when I go down through the sub div levels of my low res model I dont see a change?

Sorry to be a pain,:frowning:

#8

goto low poly model subtool (turn off smooth subdivide below
the subdiv slider till you few levels up (better results) subdivide once then hit project all repeat at every level till you have all of the detail that you have sculpted sofar. :stuck_out_tongue:

#9

your low res mesh is getting projected onto your high, not the other way around as you stated.

from what you’re writing you have the steps down. I think I’m going to need to see some pics to see where the problem is coming from. A video of your workflow couldn’t hurt any either.

#10

Hi Jawa64 and Beta chanel,
Thanks so much for replying- I will try them both today and let you know how I get on.
:slight_smile:

#11

Okay, so just to clarify again : (sorry sometimes you do need to ask idiotic questions)

1-load both tools
2- append the lp model to the hp model
3 -go to the lp model at highest sub div and press store morph target?
4- go to the lp model and press project all-do this on the lp model for all its sub divisions.

Okay I did that and its looking not to shabby:) hurrah please forgive me for the last question as it is confusing to a newb…

Which model should I save and do i need to do anything else before i save it?

Thank you so much for your help, I have watched tutorials but sometimes they assume that you have extra knowledge…and as you see I have none…:slight_smile: lol

#12

Just so I am not expecting big things and I have understood this correctly.:slight_smile:

The project all button is to transfer all the high res details onto my low polycount mesh

I have created a character ( i will post images in a mo) which is 668 polys it is a very basic biped chracter. The higher res version has no extra detail it is just higher poly and smoother version.

So i am right in thinking that the higher res will be on the lowest poly version because when I look at the low poly count one it is still the same blocky character… So am I not understanding something…ha ha probably all of it.

Sorry to be a giant dumbo, but if I don’t ask I won’t learn.:slight_smile:

Let me just go sort the images to show you professionals.:slight_smile: Project all Dilema.jpg

I don’t think you quite understand the point of projections. The point of projections is to transfer details at high resolutions to create maps that will deform your mesh in a render engine/lighting engine.

The LP character you have matches the HP character except for the smoothing/roundness. The point of the maps that you generate from that would be to create displacement or normal maps to help you achieve the same look on an animated character, or for just renders, etc.

Project all for transferring details from one mesh to another. Basically, it allows you to not worry about topology when you’re sculpting so you can just be artistic, but then once the tech side comes into play (proper loops, etc). You can generate a proper mesh for animation and then transfer all of the details that you sculpted onto that mesh.

Not sure if that makes any sense, but I think it does.

#14

Ahhh I see. I was expecting the project all button to do the work of a displacement map. Doh!!

Thank you for clearing that up for me Beta Chanel, I was getting really confused.:slight_smile:

This little man will hopefully be going into unity. So now I am off to read up on Displacement maps and normal maps

Thank you very much for all your help, I hope you weren’t giggling too much :slight_smile:

I try not to giggle…chuckling though…only a bit :slight_smile:

:slight_smile: Ha Ha I do get myself confused:) Thank you very much for your help Beta:)
