Substance 3D plugin for Unreal Engine 5

[Shwetha23063442qtvs]

Hi everyone!

As you may have heard, Epic announced and released Unreal Engine 5 yesterday, and we are excited to announce that we have released a soft launch of a new version of the Substance 3D plugin compatible with Unreal Engine 5.

If you're interested in testing out the new plugin, you can download it directly from the Unreal Engine Marketplace: https://www.unrealengine.com/marketplace/en-US/product/substance-plugin.

Stay tuned for the official release, and if you have questions or comments, please reach out to us here. Thanks!

Hi Jakob, we just released an update with a fix to this issue to the marketplace. Glad to hear this is working for your project now!

Cheers,
Aldo

I updated Substance 3D for Unreal Engine and not only did all the past textures break, but now I can't adequately install the new ones. HELP what is the problem? Can I download an older version of Substance 3D for Unreal Engine somewhere?

Came here for the same thing, seems like the latest update broke some things:

- The master material's name changed from Substance_Basic_Template -> Substance_Standard_Template. This breaks all of your material instances since it removes their master material... I don't suppose there's any way around manually going through and re-setting the master material on every single material instance in your entire project?

- baseColor now seems to be plugged into World Position Offset, but why? @Bogdan24732937f4fw this is your issue, btw. Just Show Engine Content and search for Substance_Standard_Template (it's in Engine>Plugins>Substance In UE5 Content) and unplug baseColor from WPO.

Hi @uJelleh, I'm sorry to hear about this. In the process of updating templates for the UE5.0 release, some of the templates in the previous version needed to be removed or reworked into updated versions. No templates should be removed in the future as we continue to finalize them in the beta. For now, these will need to be relinked manually by opening the material intance and chosing "Substance_Standard_Template" for the parent.

As for the baseColor node, that connection should not be there. We'll be updating that shortly.

Best,
Aldo

Hi, 

What version of the UE plugin are you using? [The plugin automatically detects the version of the Unreal engine and downloads the necessary plugin version that's compatible. For example, if you're using UE 4.27, then when you try to download the plugin from the marketplace, it automatically downloads the compatible version.]

I've been having an issue with image inputs with SBSARs in UE5. It seems like you can give it any image type you want as an input, but only jpegs seem to actually be read. I'm trying to build a system that allows artists to add height maps as image inputs, but that requires high bit depth gray fromats like PNGs in order to get the needed detail.

There is no error message or visual corruption when using a non-jpeg format, simply nothing happens. For UE5 it seems like you got rid of the SubstancePNG, SubstanceJPG & SubstanceTGA import formats so I assumed any standard image format would work, is that not the case?

Any help would be appriciated

Thanks for reporting this issue @Pip24890587eo84. We'll investigate this further. 

[Shwetha2294297372w1]

I would like to add that we have prioritized this issue and will have an update soon.

I don't know if here is the right spot for bug reports for this plugin.

In UE5 in the Substance graph reference. If you have a dropdown menu (in my case it's with INTs) in which some selections use not common letters (in my case é) these selections are not choosable.

It's not detrimental to my project, but I thought I should report it 

[Shwetha2294297372w1]

Hi, This is the right place to report the UE5 plugin issue. 

Thanks for reporting this issue. We are encountering this behavior for the first time. We'll investigate it further.

[Jakob24507899dxcs]

If you need more information to recreate the problem, please contact me through my adobe account

[Shwetha2294297372w1]

Sounds good! Thank you. 

[Shwetha2294297372w1]

Hi, Could you share the Sbsar file for testing this? 

Thanks!

[IkerGB@StellarEnt]

Hi! Are there any plans to offer the plugin in a way that is more friendly for custom source builds? The Houdini plugin from SideFX can be downloaded separately to be included as an engine plugin but I don't see a similar option for Substance. Thanks!

[Shwetha23063442qtvs]

Hi,
We used to support this in the past for C++ projects, but sadly it's a lot of work to ship two different types of plugins and maintain them.

Do you use C++ or Blueprint primarily?

We don't have any near-term plans to add this support, but your use case will help us understand the usage better.

Thanks!

[IkerGB@StellarEnt]

We mostly use C++.
Thank you for that information, I integrated the marketplace version into our custom engine compile with minimal issues so it's not a deal breaker.
At least a guide so developers know how to integrate it would be nice.
Thanks!

[Shwetha23063442qtvs]

Glad to hear you were able to get that working with minimal issues. It would be great to understand your process of getting that working and the issues you ran into.

We'll look into adding some documentation, so other developers can benefit from it.

Hello,

My project with enabled Substance3D plugin crashes (5.0.3-20979098+++UE5+Release-5.0)

Fatal error: [File:D:\build\++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\LinkerLoad.cpp] [Line: 4470] 
SubstanceTexture2D /Game/ModularBuildings/Textures/Alternating_Wood_Floor_INST_ambient_occlusion.Alternating_Wood_Floor_INST_ambient_occlusion: Serial size mismatch: Got 1205, Expected 528

I've already cleaned project, without any results.

Is there any known case of influance other marketplace plugins i.e. TrueSky?

[Shwetha2294297372w1]

Hi, this is not a known issue. Are you experiencing this issue with all of the sbsar files? Could you share more information about this issue to reproduce it on our end?
- What OS are you using?
- Does it happen as soon as you open a project? 
- What happens when you uninstall the Substance plugin? 

[Jimmy3542915805ht]

I know this is resurrecting a dead cow but did you ever solve this problem?  I'm having the same issue in UE5.3.2.

[Aldo_3D]

Hi @Jimmy3542915805ht , we'll need some more info on this as we have not reproduced this on our end. Would you be able to provide the repro steps that lead to this error? For example, does the error occur when loading an sbsar, packaging a game, adjusting parameters, or simply enabling the plugin? Additionally, it would be good to know the OS you are using and the plugin version as well.
