Thanks for this thread.  I just had the exact same issue.  Only I had been using my CC3 characters in my UE4 scene no problem, looked great, and then I powered up one day and all the sudden my characters looked like ghosts.  
I spent two days trying to figure it out, and just deleted my post prccess volume and that seems to have fixed it.

Hey there Mikay²,

I went to your "ticket", grabbed Gabi and tried her out...same resolute as you.

I did notice that, correct me if I am wrong, everything was imported from DAZ including Gabi. If that is in fact the case, that "could" be where the problem you are having lies. Those look GREAT in CC3, BUT not very good at all in UE4....especially the hair; it has about a 90% failure rate, for the hair you "should" use what you can purchase on the Reallusion Store/Marketplace without a LOT failures! You can try the DAZ hair but it could take a while to get what you would like (I have tried about 25 or so, only one or two came close to working correctly...they don't look bad just NOT great). Also getting the "skin" right will take some time for the shaders and lighting to export correctly into UE4.

IF you are wanting to bring Gabi into UE4 because you like her face (she's very pretty!) You can try the "Headshot" and Iray plugins if you purchased those here at Reallusion. You WILL have to adjust the lighting to get a good diffused lighting that you will need to get her face right then use Iray to get close to 4K, then use the Headshot plugin. I just did a REALLY quick try doing that and got Gabi looking like she needs into UE4....BUT I didn't have the lighting right in CC3, BUT she looked like how she is suppose to look going from CC3 to UE4. Just know that it will be a time consuming project, it's mainly getting the "lighting" right!

Perhaps this will help as well (I never had tried it out though). Character Creator 3 Tutorial - Auto-Load and Bake Daz Textures

One last thing....if you are using the iClone Unreal Live Link for ANYTHING or just have that plugin in your UE4 project you WILL get an error message EVERY TIME you close out UE4, they know about it, hopefully they can get that bug fixed soon!

Anyway I hope all of that makes sense and it will help you out with your project.

Have fun creating!

Hey Luis,
I was thinking about this last night but I was too tired to reply...

Are you using the PP from that level? How about the "Fog"? If YES..both of those together may be your problem...try getting rid of both and starting with the default configurations...then you can adjust there. Having "somebody" else's setup may NOT work properly for what you are looking for.

The other thing, I think in most cases, you build your level, then add, PP, lighting FX, fog etc (that is why it is called POST processing). It will save time from having to adjust it every time you add something new....you just have to adjust a few times at the end to get "the look" you need for your project.

Can't hurt....so give it a shot.

Hope that helps as well!

I meant, 'unticking' the hollow option.

 

I have the same issue and posted it some time ago, but my ticket was simply closed with the comment that it was no bug - although it is obviously is a bug.

Hi @unit23,

I have tried ticking the hollow box as suggested, but it has no effect at all in the scene, as shown here:


However, when I play with the exposure compensation a can see improvements in the skin shader as shown here:

WITH EXPOSURE COMP SET TO 1 IT STAYS THE SAME:


BUT WITH EXPOSURE COMP SET TO A HIGHER VALUE THE SKIN IMPROVES, BUT THE REST OF THE SCENE IT'S OVER-EXPOSED



Any ideas?

Regards,
Luis

That is very strange. You can quickly disable the PP when ticking the option at the bottom of the Brush Settings panel, called 'hollow'. Then it only affects items inside of the volume.

 

Hey Sam,

Thanks again for your reply and your help. I have identified the culprit to be the EXPOSURE settings under the PostProcessVolume. The main problem is, I can adjust the settings to make the skin look good now, but that makes the level itself to be completely over-exposed (you know... cause happiness can never be complete... ever), so I will keep tweaking settings and trying to find a way to create balance within this lighting chaos cause, to be honest, the affordable landscape maps are amazing and I really want to be able to use them.

Thanks again for your help,
Luis

Hey there Luis!

GREAT...now at least we KNOW what the problem is/was. So if can just play around with that post processing volume (PPV) in the settings in the PPV details panel (from that level). Then post your findings here on what you did to get that one working properly (or even if you just start over with new to see what it does)....that WILL help out others here to know what to do in case they run into that problem as well!

Have fun creating!

Thanks!
Sam

@FAITH BASED GAMES,

After a quick testing round, I can confirm the issue is the PostProcessVolume. What I don't know is WHAT is it inside the postProcessVolume that causes it. I'll try playing with the settings in it to see what happens. But please, if you have any ideas do not hesitate to share!

Thanks once again.
