Full walkthrough video. Starts with updating the bridge to work with Unreal 5.7 and ends with a character that is set up with physics, a control rig, materials usable for path traced renders, LODs, and playable in level. Enjoy!

The biggest improvement with DQS is that it preserves volume and does corkscrew rotations instead of collapsing like twisting a wrapper. Here are pics explaining that.

And a 90 degrees twist in DQS just to show how it looks without extreme rotations.

ARE there even any tutorials out there which show this process... I mean, I can send a car into Unreal no problem, and its beautifully texture and even has a control rig etc ready to go... but then what?  How do I set it up for animation?  

Does anyone know how to do vehicles?

Technical Overview Movie

Despite some minor differences in the skeleton structure, the process works seamlessly with all Daz Genesis 8 and 8.1 figures, both male and female, with or without anatomical elements. The system also works perfectly with the higher resolution FBX characters exported by the DazToUnreal plugin.

Once the converted character has been manually imported into the Unreal Editor, applying JCMs using posedrivers, setting up physics, converting standard UE control rigs and other animation tasks all become relatively straightforward. Compelling, realistic mesh deformations across a wide range of body positions that are not possible with the standard Daz JCMs become achievable.

Detail

There are two parts to the conversion process. The first is a Maya Python script that takes the FBX file exported from Daz3D and rebuilds the skeleton for optimal UE compatibility:

 ~ Converts the joint rotation order to XYZ
 ~ Reorients all the joints, pointing X down the joint and making Z the primary swing angle
 ~ Reorients the root node
 ~ Converts all inline twist bones to leaf twist bones
 ~ Adds the standard Unreal IK joints (optional)
 ~ Adds muscle joints for 'jiggle' effects (attach physics bodies to drive morphs, optional)
 ~ Adds extension joints to finger and toe tips for VR grabbing and precise IK solutions (optional)

The second part of the system is a Daz script that, when used in conjunction with the Maya script, produces a definitive set of JCMs by effectively sampling mesh deformations for a wide range of body positions. The resulting JCMs are optimised for the UE's linear skinning method - Daz uses the dual quaternion skinning method, so this is necessary for good results.

The character mesh is also combined with the clothing meshes during the process, so all exported JCMs (and other morphs) are applied to all meshes at once. This virtually eliminates poke-through issues and makes the application of JCMs at runtime a far more efficient process, especially when used in conjunction with Unreal's posedriver technology.

We also produced a cut-down version of the skin materials optimised to minimise draw calls, enhanced them with micro-normal and micro-roughness maps taken from the Metahuman project and added configurable 'Selective AO' masks for problem areas like nostrils and ears.

An IK retargetting rig, standard backwards / forwards control rig, ground following rig, eye tracking rig and semi-automated method for characterising the figure in MotionBuilder have also been produced.

Background

The system was originally developed so that we could include Daz characters in the VR meeting application we are developing, as we wanted to make the extensive Daz3D catalogue more accessible for avatar creation. It has since turned into a project in its own right. We are considering offering either a Daz figure conversion service or selling the system. There would be some work to get the system to a marketable state, so we thought we'd showcase it to try and gauge the level of interest. We'd very much welcome your comments and feedback!

Has anyone tried to create a realistic physics asset in Unreal on a Daz character ?

I'm trying and find it to be a real nightmare: some bonetwists seem to be carrying the vertices instead of the bones (ex: forearm vs forearmtwist), which makes automatically generated constraints weird and wrong.

And trying to manage constraints manually require a patience that is not from this world.

After 3 full evenings banging my head on the walls with trials, errors and UE5 crashes, I would gladly pay the price of an asset if a seller did a good job at that and put it in the shop, but i couldn't find anything of the sort on DAZ shop, nor on UE's markerplace (fab.com).

Easy export to UE is advertised, but, although the D2UE bridge does a great job in certains areas (material management, etc.), some essential features are lacking (i.e. PA !).

Is there any trick i'm not seeing ? 

Thanks

Seriously, this is killing me. lol. So I use Daz3d imported characters. Took forever to figure out but I got everything setup properly with the Daz to Unreal plug-in provided assets. IK, skeleton, retargeting, blah blah, all that good stuff. But retargeted (and sometime imported) animations still leave The "twist" bones a mess with a mind of there own. In Daz characters it shoulder, forearm, and thigh twist bones. 

There has to be a way to fix this, right? Because trying to keyframe fix them is a **** show that usually just makes it worse, and takes forever.

Can they be locked to the angle of the main bone, or a virtual bone? Some type of change, fix, adjustment, Something, or in the long run they are basically unusable. 

Please help! Thanks.

"Missing Modules

The following modules are missing or built with a different engine version:  

DazToUnreal

Engine modules cannot be compiled at runtime.  Please build through your IDE"

 Is there a fix for this?

what should I do?

Thank you!

1.The first concerns physics simulation and hair: using UE5’s Chaos Physics really impacts my project’s performance. I’m a beginner and I was wondering if you have any tips or solutions for this? Would it be better to use bones with a rig for the clothes and hair?

2.The second is a problem I’m encountering with Physics Assets: when I apply a ragdoll or run a simulation on my character, for example, the arms break in two. Even though I’ve recreated the physics assets, I still get the same weird result. Has anyone experienced something like this?

Thank you very much !

When using the bridge to export from DAZ to UE5.2 I'm getting warnings inside UE regarding missing bones from bind pose. And when I try to play with the new character the animations looks weird and wrong.

I'm attaching here a link to my google drive with a video that show the problem.

Anyone knows how to fix those issues ?

https://drive.google.com/file/d/13tO5GcolH5jssx1UMJ-GRYR3bvp2y238/view?usp=drive_link

I tried uninstall & install it again in the DIM but nothing changed.

Any idea how to fix it?

I've tried several pipelines for this task, but I found that using Blender is slow and cumbersome, using MetaTailor is somewhat limited (and makes you dependent on a software with a 35$/month fee), and using UE5 tools themselves can be quite sloppy. So I guess my question is - is there a script, or any other way to quickly alter the default Daz clothing poses to fit any singular DNA/Template Metahuman A-pose?

我从插件详情看到这句话：

支持的目标构建平台：在 Win64 上测试，但应该可以在任何平台上运行。

是否有人成功发布到ios？急切等待中...

If anyone can help me out i would really appreciate it :)
