*@Erik Dahlbäck* I explained it just before 4:30. When doing expression tests I often ran into issues on the lips & eyelids when they also had the details of the sculpt shrinkwrapped onto the multires. In 5:30 I explain how to exclude the lips & eyelids from getting the detail of the original sculpt.

I can recommend this because you get more control and predictable results when sculpting the expressions in those areas that way. In hindsight it's actually unnecessary to switch to the subdiv modifier. Just toggle the shrinkwrap modifier to see how the lips & eyelids would look without the details of the sculpt and make sure it looks as similar as possible.

*@Julien Kaspar* I guess you mean toggle the eyes and mouth vertex groups disabling in the shrinkwrap modifier on and off and check that there are no big differences?

*@Erik Dahlbäck* Essentially it's about comparing the lips & eyelids with & without the shrinkwrap, or at least comparing them directly to the original sculpt. Make sure they look as similar as possible.

It's hard to tell. Maybe you could send me a file? In the latest (and upcoming) version of Blender 2.91 there is a new brush that makes this a bit easier. Instead of using vertex groups to prevent certain ares from shrinkwrapping you can use the "Multires Displacement Eraser" brush to remove any shrinkwrapped/sculped details from the inside of the eyes/mouth. Set up some face sets to easily isolate/mask those areas and then go over them with the brush. I hope you know how the face sets feature works. I do plan on adding them to the course at some point with some extra videos.

@Julien Kaspar https://drive.google.com/file/d/1lVn4BrAIYcuYPYhfxfHsQIQ9UatBLOrz/view?usp=sharing it is doing some weird stuff anyway, I am afraid I have done something wrong along the way...  Thank you very much for the help! I will also try using this eraser and see how it goes  :)

I found out the issue. Your vertex group is empty. Nothing is assigned to it. If you switch to Weight Paint mode you can easily check how your vertex group looks like in the form of a heat map (red is 100% and blue is 0%)

@Julien Kaspar I am a bit confused, I am quite sure I assign it. When i click "select" it selects the vertices I assigned.  I just now quickly tried the weight painting and it does work! I am quite confused as how this whole thing works and why it refuses to assign normally?. I am very happy I learnt about the weight paint! I still have some issues with geometry going into itself when it works, but it looks better and now at least the vertex group exists, so thank you very much!

@Julien Kaspar I am sure I have done something wrong somewhere, but honestly I have no  Idea what it could be or when I did it.  https://drive.google.com/file/d/1thwcfWHlPrIB4QhWrAU5xhTe3bGxlon8/view?usp=sharing I have made a small video with the issues I have and I  honestly do not know how to fix besides removing the inner eye completely.  I would be extremely grateful if you could take a look at the video and tell me if you find the problem... could the issue be the sculpt itself?  Thank you very much once again.

@Miranda Guerriero @Miranda Guerriero What's mainly causing your issues is that the retopology you made has a very different shape from your sculpt. If you disable the shrinkwrap modifier you can see the big difference. If you then remove parts of the geometry from the shrinkwrap modifier via a vertex group there will be a huge divide in there. I can highly recommend to regularly copy & apply the shrinkwrap modifier to make sure these things don't happen.

@Julien Kaspar okay, I'll try to make it once again, to make sure this doesn't happen!  thank you

*@sanepark* never mind! I just saw you treated this with inflate brush in the beginning of the next clip! Solved!

@phunky.doodle There are 4 icons on each modifier. The display icon is disable it for the viewport. The others are for disabling it for rendering, edit mode or from the wire-preview in edit mode.

@Arnaud My first guess is that these are because you are adding and applying Mirror modifiers? These do not auto-delete the other side when mirroring, unless the "Bisect" axes are toggled.

The easiest way to get rid of this issue once it's to latte is to use "Merge by Distance" on the shortcut M. But that might not be enough in some cases, which can be very tiem consuming to fix, yes.

@Julien Kaspar Thanks a lot for your fast answer ! Indeed, I must have been a little negligent with the mirror modifiers ;)

*@bellasalvador1014* I was able to fix the weird clipping with the smooth tool in sculpt mode. Not sure what happened there.

@Ekin Kılıçdere You apparently assigned the eyes and mouth area to the vertex group instead of everything else. So your vertex group is ivnerted. But it's fine. The 2-sided arrow button on any modifier will invert the effect in the modifier for you.

Also, I've tried using a smooth modifier which helps, but I also loose definition when I use it. And one more thing, I can't view vertex colors in any mode except vertex paint, unless I'm in lookdev or rendered view. Why is this?

@ben.gerberick

• The ears don't look rough because of bad topology. It's shrinkwrapping exactly to the original sculpt but there is not enough resolution there. Try switching to flat shading instead of smooth shading on the original sculpt to see better what the geometry actually looks like. You can also just smooth over the ears a bit in sculpt mode once you have the shrinkwrap modifier applied.
• Ideally the mouth and eyelids should look like the sculpt by modeling them that way. It's tricky but it's better than shrinkwrapping the original sculpt on it. If you are fine with how it looks different you can also keep it that way.
• You seem to be using vertex colors but do you have the experimental feature "sculpt vertex colors" enabled? These are 2 different things and the solid viewpoint will only display sculpt vertex colors if this feature is enabled. If you turn the feature off it should work.

@ben.gerberick Apart from that the topology looks fine.  The eyes look very bulging so maybe push them a bit more into the head and fit the eyelids around that.

Thanks! @Julien Kaspar. I appreciate the feedback. And yes I think I did not understand how sculpt vertex colors worked. Thanks for actually answering!!

@Keshav Chaurasia That looks good for now to me. Try out some expressions on it. You can always go back and adjust it if it doesn't work.

@Julien Kaspar  I fixed the weird glitches on hte edges and am doing the expressions now!!
