*@Artur Machura* The reason why the base resolution is not changing and hidden geometry in edit mode is not hidden in sculpt mode is because you are sculpting on the subdivided version of the object.
The "Sculpt" slider is there to define on which subdivision level you are sculpting when entering sculpt mode.
Sculpting on subdivsions will not translate to the lowest resolution automatically. I'm sorry, I forgot to add additional info to the chapter description. In Blender 2.81-2.83 the multires modifier lost the "Sculpt" slider.
So when entering sculpt mode you will always sculpt on the highest subdivision and if you want to sculpt on the base resolution of the object you need to disable the modifier temporarily. Adding the button to quick favourites will help to make this easier.
It's still inconvenient but if you download the experimental version of 2.90, the multires modifier is finally fixed.

*@Julien Kaspar* Thank you. So obvious, why haven't I thought about it. Thank you for the quick reply.

*@Artur Machura* It's obvious once you know it ^^
I will do my best to update some of these videos soon to have this info already in the tutorials.

*@Julien Kaspar* I don't think a lot needs to be updated and it that fix would get its way to 2.83 than probably it could stay as it is. This is the first time I get to the point I didn't know what to do but at this same time, I am not a total beginner so as you put it I may know things that for me are obvious now and I overcome other problems that could be difficult for others.

Any new chapter soon on the horizon?

*@Artur Machura* No new chapter yet. Other projects got more priority and I don't know when I can return to the other chapters.

*@JacoFourienwu* Nevermind i figured it out the 2 values of my shapekeys were different values when i tried to combine it

*@andreanselmo100* That is actually a really good question. If you delete one side, mirror the other and flip the normals manually, then the details from the multires modifier will be broken.
I found a workaround that I should include in this video soon:
In edit mode press F3 and search for "Symmetrize". You can then define which side get's mirrored and it will not break the multires details.
it will still break all Shapekeys though if you have any.

*@Julien Kaspar* Thank you!

*@Sosa* Hopefully it will soon get simpler but so far you have to do it like this: https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet#images

You essentially just embed an image that is already uploaded somewhere on the internet.

@joanneseale Yes you need to sculpt on the lowest resolution. The toggle for "Sculpt Base Mesh" sadly doesn't work with shapekeys. What that toggle does is it lets you sculpt on the lowest resolution while seeing the higher ones.

@Gabriella WauyeTo make creating and pasting drivers easier I can recommend to right click on a value and clicking on "Copy as New Driver". Then right click on another value and use "Paste Driver".

@Julien Kaspar I've tried doing that. The eyelashes move to the position of the eyelids. But when I move the eyelids after, the lashes remain in the same position.

@Gabriella Wauye Hmm I don't have enough info to find out what could be going wrong, sorry. If you could record a video of your screen, showing what you are doing in full, and showing how it doesn't work, then I could help.

@Gabriella Wauye Ahh! You copied the name of the shapekey as a driver. You need to right click on the value instead.

@Julien Kaspar it worked!! Thankyouu:)

@Jonathan Doe Since all of the expressions are made with shapekeys and hooked up via drivers to move together, it would make more sense to add shapekeys to the teeth and gums.

Parenting makes more sense when you plan to move the objects instead of the mesh within them. But moving objects and shakekeys together can not so easily be set up with drivers.

@Julien Kaspar

Sad to say but the concept of “drivers” doesn’t make a lick of sense of me but I’m sure that’s something I’ll come to understand as I watch more videos, lol!

If I don’t understand still, I’ll be sure to hit you back up. : )

@Jonathan Doe Sorry if it wasn't clear. In essence what drivers do is that they look at one value you specify somewhere, and then copy it.

It's like saying in code x = y. If x is 10, then y is also 10. If you then change x to be 20, then y also changes to 20.

So if you have a shapekey for an open mouth, you can make other shapekeys driven by that one, like shapekeys on the teeth & gums. So if you slide the shapekey for the open mouth to 1, then the other shapekeys also turn to slide to 1. So they move together with only one slider.

You can even do more with drivers but this is the basic concept that is useful here.

@Dione At some point I've learned an easier way of adding drivers in Blender. Try right clicking on the value of the shape key and click on "Copy as New Driver". Then on the shapekey that should have that driver you can right click on the value and press "Paste Driver". This does the same what I showed in the video but sets everything up for you automatically.

*@Nly Arivony* I think I did a poor job explaining this in the introduction of the chapter.
To reiterate on the reasons why this step exists in the character creation:
In past movie productions it happened that we designed, modeled and rigged a character before even figuring out the exact animation style. This caused huge problems during the animation, since the model was not fully supporting all the deformations that needed to happen.
Doing some early expression tests for sculpting has 3 purposes.

• You end up with a set of sculpted expressions that will be a style reference for rigging and later the pose library in the animation.
• Any facial proportions that are not working well can still be tweaked so that they won't become an issue later (Like misplaced eyebrows or too small teeth)
• The amount of compression, stretching and creases will help to later retopologize a more optimal model for rigging to capture not just the shapes of the resting pose but all possible and planned shapes of the animation.

Unfortunately there won't be a rigging tutorial attached to this character but the animation fundamentals course might still add some videos using the Rain rig :)

*@Julien Kaspar* thanks a lot

*@madonna* Perhaps you right clicked on the name instead of the value of the shapekey?
I'm also going to make an update video on this but as a tip: Use the "Copy as New Driver" and then just paste the driver on the other shapekeys instead of going through all the steps manually.
This will save a lot of time.

*@Julien Kaspar* Hi Julien, you are right!. Thank you very much to your response. I also tried to downgrade Blender but nothing change. it is very much aha! Once you told me it is very much easy... I can keep going on the tutorial now. Thank you very much again!

@Gabriella Wauye There's no link to a video in the comment.

@Jonathan Doe I am recommending to use vertex groups as a way to quickly hide and mask parts of the emsh. But since these videos were recorded there is a more direct better way directly in sculpt mode. Try out the face sets feature. That might be clearer and easier.

@Julien Kaspar

I think maybe I asked my question wrong or wasn’t clear.

I decided to take a screenshot of the area where I’m having issues following your model and instructions with mine that better showcase the problem with my question being inside the notes in the google doc. : )

https://drive.google.com/drive/u/0/folders/1Oq3311r-SeWuZ44-wRG9icdqQOMbSxtV

I am sorry my question is long and tedious. :’D But I provided a more detailed image comparison and my most recent file so hopefully it will make sense.

Thank you!

PS: I'll mess around with the face sets feature but from my brief attempt at trying to work with it, it did not seem to help in my current situation ( although I like the practicality behind it ).|

PPS: I updated the google doc with a "question 2" image that better shows what the "question 1" image neglected to show.

@Jonathan Doe When enabling mirror options in edit mode, it only mirrors deformations and transformations. Selecting and editing the topology will not mirror.

@Jonathan Doe These are Face Sets. They are sometimes automatically created when editing the mesh or joining objects. They don't do anything by themselves and can be hidden in the overlays if you don;t intend to use them.

@Julien Kaspar

Thank you! This resolved my issue. : )
