Looking for cool skin/hair care 3D demos and a related modelling question

Hello, I recently joined a production house that makes a lot of skin and hair care videos which include 3D demos. There are lots of demos like that out there but very few look professional enough. I wonder if anyone here kwows where I can find this kind of work to use as reference both for project planing with my boss and for the work itslef. 

 

Also, since this is a very specific type of 3D work I'm constantly stuck as figuring out where to begin the scenes. For the next project I need to create a scalp with hair follicles that show how they debilitate over life. My first challenge is to model the scalp with the pores where the hair grows from. I'm thinking creating the vault with a boolean of an sphere inside the box that makes the scalp. Then using the clip plane feature to cut the box and make the insides visible. I know there are lots of really experienced artists here and I'm curious if that's how you'd approach this, I guess not. 😛 

 

Thanks a lot.

 

Sorry I didn't notice I posted in the wrong category. I don't seem to be able to change it.

Pen and Paper my friend !

Your question is very open to interpretation as any artist here could take a shot to answer you and every answer will have a different result.

I will answer by asking further questions to establish some artistic direction and then we will help with the technical.

    What do you mean professional ? If you are talking about the advertisements on TV they are very professional. What they are not is certainly medically accurate.

    Are you saying that not even their demos were professional enough ?
     

  2. Do you have an Art Director ? Does anyone provide a concept art about how hair and skin should look ? For example are we going for a photorealistic model or will it be the usual pastel-colored tones for elements ? Will it be like a cross-section of the skin with visible skin layers below or will the camera see everything from skin level and above ?  What would the animation involve ?

  3. In your description you mention hair and skin. Is this the only thing you will need help for or will there be other elements also like product placement, or some kind or artistic presentation of "fresh", "healthy", "healing" ? See hidden image below -

Hi Happypolygon, sorry for the belated response. These few days have been awful and busy. Thanks for taking the time to go so thoroghly into my post and for the references. What I meant when talking about 3D demos not looking professional enough was that there are plenty of them on stock footage platforms but very few look really well done. Not taking into account accuracy just looks. My reference is Tv advertising yes. I'm sorry I wasn't specific in this particular subject but I just assumed it was understood the TV spots demos are what everyone has in mind when talking about skin/hair care 3D animation.

Mmm they have plenty room for improvement which is my goal. I'm not a well experienced 3D designer but I want to create nice 3D pieces.

No, we're after the usual TV ad demo look. This is a very small house, there is the boss, a manager that does some postproduction work, one in-house post-production specialist and two or three freelancers that come and work in the office when needed. So I'll be the art director and also in charge of the 3D creation. As for the details of the look of the demo, those are great points you mention. I believe the approach will be a cross section of the scalp on pastel colors with semi-realistic skin layers. They're not looking for realism, there will be no glands, artheries, or anything that isn't related to the script. About the script, it's very simple. The idea is to show a cross-section of the scalp showing the insides of a hair follicle with spheres depicting the DHT hormone sticking to it, debilitating the hair. I'm not sure if we're going to need to show the hair thinning and getting loose but it's a possibility. Then there's a second part when we show how the product is absorbed by the skin and fortifying the follicle. 

 

I hope I was clear enough this time, thanks again.

I think the best modeling option is to sculpt your cubic cross-section and 3D paint it.

 

Anything involving booleans can backfire when more than two objects are involved, resulting in flickering (and slow to animate) geometry or/and flickering of materials if the objects intersect.

Hello Happypolygon, I don't know why I didn't get a notification about your response. I even went into this browser tab and didn't see it updated up until now. Thanks for your answer Happypolygon I will work it that way. I've never used 3D paint but I will certainly give it a try. Would you use it to create the "well" of the follicle? That's, at this stage, what I find more challenging.

First you need to model in classic and low-res before sending it to sculpt mode.

 

It's not that hard to make the follicle as it requires simple extrusions.

 

Although @Cerbera is our modelling guru, I think the following steps are acceptable:

 

First delete some polygons in order to see the negative extrusion.

Then select a polygon where the well will start to form from and begin making multiple extrusions. In each step scale and move the base polygon to be on the same level as the front face of the cube, also delete the new polygon that obscures the visibility.

Next using Weld and Bridge make adjustments to make a nice topology

I used the Remesh to increase the number of polygons a bit. Then I made some sculpting subdivisions

For more pronounced edges I used the Flatten sculpting tool with the following settings and used the Front viewport for constant level.

Then you model your hair any way you like as a separate object. 

 

WARNING

If you plan to animate the follicle (for example make it disappear after the hair is removed) then I don't think sculpting it is a good idea.

If you want to animate the structure/volume of this cross-section then I think the Volume Builder is a nice solution.

Unfortunately you won't be able to paint on the volume builder but there are techniques in R2023 (I don't use R2023 currently) that enable Fields to colorize your mesh and with the proper use of vertex map tags and vertex map shaders you can blend complex materials on the parametric Volume Mesher through fields.

Thanks again Happypolygon. I'm more familiar to that kind of modelling, however I don't seem to fully understand some of your pointers. I'll start modelling and then come back if I run into a problem. I know @cerbera, he/she has helped me a lot in the past. Can't wait to see if he/she comes up with a different approach.
