Solved: 3DO -consistency- UE4

Maximum-Dev · Dec 2015

Hello,

I'm new to Suite 2 and really liking it so far, however, everything looks real good in 3DO but once in UE4 textures look a lot more saturated and darker.

In suite 2 there are these two HDRi images from UE4 but selecting them and putting PostProcess on either UE4 options doesn't do anything like default UE4 level. (and maybe not supposed to) but either way, how do you get a 1:1 look?

Hey, Maximum!

One only need to select the Unreal 4 post-processing option(s) in order to enable 1-1 previewing. 3DO's shader code is identical to UE4's code when either UE4 post-processor is enabled.

If you continue to see discrepancies between UE4 and 3DO, please post images for us so we can take a look into it!

Hi SYNAESTHESIA,

Here's UE4, 3DO PostProcess1 and 2 in order. (UE4 image is a new level created and only sun rotated to have the light coming it from front). In the both 3DO images I have rotated the HDRi so the light is coming from front.

Thanks for posting that! May I take a look at your material as well?

As you can see the texture is closer to the render is UE4. I think it's 3DO being inconsistent here.

Synaesthesia · Dec 2015

I actually meant your Unreal 4 material.

Maximum-Dev · Dec 2015

Ow sorry, here it is.
(Second map is Metallic/Roughness/AO set to Masks compression).

Synaesthesia · Dec 2015

How is your *_reflection.* texture compressed? May I take a look at the *.uassets and the project?

Maximum-Dev · Dec 2015

It's set to "Masks" compression in UE4.
(Having Metallic in R, Roughness in G, AO in B channel).

PM'ed you the project.

Synaesthesia · Dec 2015

I looked into the project and UE4/3DO have the same shading, but the lighting is a bit different in the skyboxes. It's something we'll take a look at in the future. Thanks for the report!

Synaesthesia · Dec 2015

Upon further inspection, there's potentially an underlying issue that our 3DO engineer will take a look at. In the meantime, would you be okay with visiting Quixel Live Support and reposting this issue there?

Maximum-Dev · Dec 2015

Thank you for taking the time to look into it. Posted on there as well. Hoping this will be sorted out soon.

Okay so it was confirmed on the live support page that this is true and 3DO is not consistent with UE4. And with 2.1 out it's still not fixed and I'm not able to use the software yet. I assume this problem is still being worked on or it becomes the same mega scans story?

Maximum-Dev · Jan 2016

Okay got it figured out.

When you are texturing in suite 2 you have albedo, roughness, normal and metalness channels.

there is no specular channel there to work with because specular for non-metals is almost the same.

But before they implement metallic workflow in suite 2 it was only for specular workflow like cryengine and specular for non metals in that workflow is ~56,56,56.

Now when you are texturing for using in UE4 that specular channel isnt there but it's still affecting the render in 3DO with a value of 56,56,56, making a huge difference in the render. But in UE4 the specular for non-metals is ~10,10,10 So in suite 2 you need to add new map > specular, set opacity to 0 for all channels except for the specular channel and move it above all your layers and set it's specular value to 10,10,10 then you get the same look in 3DO as in UE4.

Edit: I also have to mention both UE4 post process presets in suite 2 are incorrect when compared to UE4 so better use one of the Clean presets to get an even closer look.

2 Updates came out but this is still not fixed.
Specular value is still wrong for metalness workflow.
All smart materials also have specular values set for the specular workflow. None giving 1:1 look with UE4.

I assume quixel interpret 0.5 in UE4 equal to 128,128,128 in photoshop. But it's not, and hence, all the smart materials are useless for metalness workflow unless manually fixed by the user.

Come on...

Synaesthesia · Feb 2016

We're fixing this ASAP. Sorry about the wait, it's taking us a bit of time to make sure it's done right.

Maximum-Dev · Apr 2016

Hello,
I saw the 2.1.5 changelog. Not sure if this is fixed or not.
"Fixed a bug in Standard shader GGX specular term" Is that referring to this particular issue with UE4 ?

Synaesthesia · Apr 2016

Yep! It looks significantly better now. Give it a try and let me know!

Got it again and gave it a try. No more inconsistency like in the OP! Yay!
Now looking forward to custom HDRi loading and of course the "upcoming" megascans. ^^

Thanks.

Synaesthesia · Apr 2016

Don't put upcoming in quotes like it isn't going to happen. I see what you're trying to do.
