That’s very strange. The Aximmetry UE5 is essentially identical to the regular UE5, apart from some changes to how video planes are rendered and some blueprints hooks into Aximmetry. There should be zero difference in image quality and I’ve never seen a difference myself. Are you opening the same project in both UE5 versions, or is the Aximmetry version a copy of the original? Depending on your rendering settings, the same scene can look very different, so make sure to open the exact same project in both versions to rule out that some setting is different.

If I were to guess, I would say the difference is with Lumen reflection settings, so start looking in that direction. 

It is the same project not a copy, I opened the same project in both but they look totally different actually after opening it with aximmetry-unreal I close the project then open it up with regular unreal and it looks as it should initially I thought that the project was modified but not it looks as it should.  I don't know what to do.

Looking at the screen shots, I can only see a difference in the scenes on the water shader? Or are there other differences as well?

Are the engine scalability settings set the same in both versions? Try setting it to Cinematic in both editors. 

Is the standard UE5 editor a fresh install? Maybe the water material shader has been edited in the engine content? I have had that happen to me, causing a scene to look different when opened on another computer.

You could try duplicating the PostProcessVolume in the scene and deleting the original. Occasionally a setting gets “stuck” and doing that will refresh all the settings.

How does the scene look when cooked and opened in Aximmetry? Note that the rendering quality will be affected by the rendering resolution you’ve set in the Project settings. 

If none of these things work, you should send the scene to Aximmetry support for them to take a look at it. It might very well be a bug in the latest version. 

I'm unsure what's going on, but after cooking it, I was horrified by how awful it looks on Axymmetry.

Can someone please explain why this happened?

As I’ve explained, this isn’t normal. It should (and usually does) look identical to stand Unreal in Aximmetry,. After all, it’s the exact same rendering engine. It’s impossible to know that’s wrong with your setup without more information. I suggest starting with re-installing Aximmetry, and then send the scene to Aximmetry support so they can take a look at it. 

Hi,

But the same project opens perfectly fine in regular unreal engine, that means is not the same(UE should have something different), if it were the same it will work in the same way, where could I send the project?

I  reinstalled  everything again, same results

Thanks,

Hi,

Firstly, addressing the errors in your project should be a priority. Starting with:

You can find this setting in the Project Settings. However, this specific error will probably not fix your other issues.

But this one might:

It could be that everything is black in the cooked (built) project cause the shaders for it were not built. This would also happen in the normal Unreal if you build (cook) the project there.
There might be other underlying errors, or the scene might have been designed in a way that it cannot be built.

Concerning the difference in quality, the only difference I see between the two pictures is the water. There could be many reasons for this, in this case, I would guess that the water's behavior might be directly linked to the default camera's position in the scene. Aximmitry uses its own camera, which you add from the Aximmetry menu, so if the water has such linkage with another camera, that will not work.
 Since Aximmetry uses its own camera system, which you add from the Aximmetry menu, any linkage to a different camera could cause issues. To test this theory, try running the project without adding the Aximmetry cameras. If the water's appearance doesn't improve, this theory probably is not the cause.

Note, that if you want to compare things accurately, you should make sure that the cameras in the comparison are at the same exact position. This ensures that the Level of Detail (LOD) levels for geometries remain consistent. Additionally, verify that the quality settings and rendering resolutions are the same for a fair assessment.

Warmest regards,

After going through all the settings I found it was causef for a HDRI settings size, anyway for me is weird since I had to modify something that shouldn't be modified is the following: backdrop size: on unreal the backdrop is 6000(it works fine) I had to make it 600000 this is related to the sky size for any reason looks like Aximmetry is downsizing it

Hi Mauricio,

There is an issue with HDRIBackdrop in Unreal 5.3 when using cooked mode (built project). This issue is present in the normal Unreal too.

You can read more about the issue and how to fix it here: https://my.aximmetry.com/post/3496-hdribackdrop-plugin-not-working-correctl 

Warmest regards,
