Thanks Eric!

Sure!... specular shine is often a contributor to this. Try cross-polarizing your lighting and camera: kzfaq.info/get/bejne/qKing6qKp9SUhJc.html Alternative could be anti-shine makeup.

@@PixelProf Awesome!! thank you so much for your suggestion! I've just watched your "DIY Cross-polarization" tutorial. And I'm going to try with that to see how it turns out :) Thanks again for your helpful videos😆

Thanks for the kind words. I don't have any "insider" information on this, but "reading between the lines" of what is shared by Epic, it looks like the system first gets as close as possible to the target using just MH zygotes from their library (complete with blendshapes), then applies a final blend shape to close the remaining gaps. You can blend between the MH result and the corrective blend in MHC in the "Custom Mesh" panel.

@@PixelProf very cool! Thank you!

Thanks for the kind words. I primarily use Faceware Studio rather than iPhone for face performance capture, so I don't have any specific information on the iPhone app.

You can export an MH head from Unreal, but it will always be the blank, “neutral” pose. If you would like to export with an expression, you would need to use Maya. If you have Maya, you can use the full version of Quixel Bridge (downloaded free from Quixel.com, not the “built-in” version in Unreal) to export the MH for use in Maya. In Maya, you can use the fully rigged MH to pose the body and/or face as you like, and use the duplicate command to take a snapshot copy of the mesh in its posed state. That can then be exported to any of a number of export formats that are supported by 3D printing tools.

@@PixelProf thanks a lot for the clarification. That's too bad. No Maya, just Blender. I guess the only way I could do it might be to pose the expression in MH then take ~70 screenshots from different angles and just redo the photogrammetry. That should work I think, in theory.

In RealityCapture, if you're exporting an FBX, you will see an "Export Model" dialog box after selecting the destination and name of the file you're about to export. In this, make sure that the "Export Texture" and "Embedded Texture" options are both set to "Yes" before clicking OK. This should save your textures in the FBX file and Unreal should read them in. Hope this helps. Have fun.

I see. Thanks so much for your reply Sir. I'll try it out.

It's a pretty old machine. The CPU is Intel(R) Xeon(R) CPU E5-2640 v4 @ 2.40GHz 2.40 GHz (2 processors).... but the GPU has been upgraded to a Quadro RTX A6000.

You can export the custom MH geo and rig to Maya, animate in Maya and export to Unreal, but I don't think you can animate in Unreal and export to Maya. (MHs are not really setup for rendering from Maya anyway).

Photos work better as they typically have stored meta-data with each image that documents camera information including lens settings that is useful for the photogrammetry software. Video can work, but it is generally less than ideal as it is much more prone to motion blur and lacks the per-frame metadata stored in most digital still images.

Yes. You can adjust head size in MetaHuman Creator. The control is in the body Proportions panel.

it stuck out to me also Fabiano.

For this workflow, scan with mouth closed. If the track doesn't properly identify the seam between lips, you can manually adjust it. The Metahum system will create a mouth interior based on pre-defined assets in the MH library.

​@@PixelProf That good to know. Mouth close ! 😁 Thanks. 👍

It seems that the plugin and MHC do not currently use the texture information from the scan. It is possible to make use of this data through the use of external tools (Maya, Blender, Zbrush, etc)

@@PixelProf That's what I thought, thanks for the quick answer! Would be nice if the features of Mesh to Metahuman and Reallusion's Headshot plug-in were combined!

​@@Pauliotoshi Well.... you can still use Headshot to generate the mesh to use in the UE5 plugin.

@@Pauliotoshi yeah external 3d softwares are always there for you if you want more skin textures but you can only render through Unreal engine

You can make these adjustments in Metahuman Creator after generating the MH with the plugin.

Its kinda weird for all metahumans tbh

@@PixelProf Oh, ok. Great. Thanks for the kind reply.

There is actually a slidebar in the metahuman creator site, is at the bottom left section.

Plugin may have been renamed since the creation of this video. At the time of this comment, it is listed as "MetaHuman Plugin" in the Marketplace and can be used in 5.0 and 5.1

For photogrammetry, the output quality and resolution generally depends on the quality and resolution of the photos provided. Reality Capture is certainly one of the best. I don't think I've used every tool out there, so can't really speak to if it is "the" best, but I've routinely used Reality Capture, Recap Photo, Agisoft MetaShape, plus a variety of iOS tools. Agisoft and RC seem to be at least on par with one-another, with RC having some more functionality and features that I don't have access to in Metashape.

@@PixelProf thank you for answering, so the realism of the character to 3d mesh is mostly from the metahuman creator then? Because I want the most realistic 3d human that I can create, but although metahumans are amazing and very easily to use, it still looks like a character from a video game, and what I'm planning is like creating an unreal engine movie that looks real in everyway, not just the environment which right now is almost impossible to know if it is real or not, but with CGI or 3d characters, one can notice that is not a real human at least with metahumans, only the demo from unity from a few months ago looks almost real, but we don't if its going to be that quality until is launch and also how easy would it be to create a CGI like metahuman does. Anyway, thank you and have a good day.

@@MiguePizar The "Enemy" demo from Unity is fantastic. I'd look at the "Matrix Awakens: An Unreal 5 Experience" as the corollary from the Unreal universe. Keanu Reeves and Carrie-Anne Moss are both almost entirely rendered in engine from about the 2min. mark on. Their characters, both present-day and "young" versions, are essentially customized metahumans operated and rendered in engine throughout the piece: kzfaq.info/get/bejne/jbtgmtmByMmXmoU.html

@@PixelProf thank you again for the reply, well, I tried the Reality Capture but the 3d output was a complete mess. it is because I didn't use a black background like you did? or Did I put too many pictures (180 or so)? I guess one of those were the problem, I'll try tomorrow again if I have time.

@@MiguePizar I'd need to see your source photos to provide input. Most common issues are.... 1) blurry photos 2) reflections or transparency in photos 3) changing light conditions from photo-to-photo 4) movement of the subject between photos There are other conditions that can make automated photogrammetry return poor results, but those are the the most typical and common.

Which software? Unreal, Mesh to Metahuman and MetaHuman creator are all free. RealityCapture has a PPI (pay per image) mode, so you don’t have to pay hundreds of dollars to use it. You would just pay a small fee based on the quantity and resolution of images used. (This example would have cost under $2 in PPI mode)

soft soft lmao

Open the Plugins window (Edit Menu->Plugins), search for Metahuman, activate the Metahuman plugin... you'll probably need to restart Unreal after that.

@@PixelProf I will try and see if works. Thanks.

no

You need to use Quixel Bridge (built into Unreal 5) to bring the custom MH into your project.

At this moment, the plugin only works in UE5.0, but you can have both 5.0 and 5.1 installed (even if one or both is on external drives). So you can use the plugin in 5.0 and upload the resulting head to MHC to finish your custom MH. Then the finished MH can be brought into 5.1 through Bridge and will work fine there.

@@PixelProf thank you

The photogrammetry can be done and imported into Unity, but the MetaHuman portion of this tutorial (that creates the fully rigged digital double) only works in the Unreal Engine ecosystem

@@PixelProf okey thank you for your fast answer :)

The raw "scan" output cannot be animated. It's like a marble bust. The utility of converting to MH is that it can be fully animated.

Yes, there is a way, but it involves going outside the pre-defined options in MH Creator.... "out of the box" MH's have a pre-defined collection of 15 eyebrow sets to choose from. Many of these are fuller/thicker than others, but within the MH Creator, there are only these 15 eyebrow designs to choose from. That said, anyone with knowledge of how to create hair grooms in other software (Blender, Maya, C4D, etc) can create entirely custom hair definitions for the eyebrows and every other hair component of MHs.
