Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

How do I removing LOD's from an object?

I don't know if I am simply dumb or if there is no way to remove LODs from an object?

Hey Kuro1n,

You're not dumb =) This is not currently possible in the editor. You will need to adjust your assets in whichever modeling software you are using. You can certainly export your static mesh as an FBX, import it into another program to adjust the LODs, and then reimport into UE4.

Best,

Ben Halliday

Thank you for responding so quickly Ben, will this possible be added later? Because if I add a model with connected LODs and then want to change something in the lower LODs later for example I would have to remove all the foliage instances wouldn't I? Or can I simply reimport the mesh and overwrite the old one thus keeping the instances of the foliage?

You can replace an Actor in your level with another in your Content Browser. With the replacement mesh selected in the Content Browser, right click on the Actor you want to replace and click Replace Selected Actors With. If you have multiple instances of an Actor you want to replace, you can select them all and do the same thing.

It gets more complicated with Foliage, however. The foliage you had painted on the original Actor will remain in the level, but it will not be attached to the surface of the new Actor. You will have to erase that foliage and repaint, unfortunately.

It's not likely that this will change, because editing Meshes is not something the editor is meant for (though there are some requests in our database for it). Additionally, the foliage referencing a face that does not exist on the replacement mesh isn't possible.

There is a workaround, however: you can add LODs to an existing mesh. Right click the mesh in your Content Browswer and select ImportLOD. This will let you add an additional LOD level. Then, whichever LOD you don't want to use anymore, set the LOD Distance to an obscenely high number, and it will likely never be loaded. That should work if repainting foliage on a replacement mesh isn't an option for you, though obviously it's less clean.

Hope that helps!

Okay, I see. Thanks for the workaround I might use that until I clean my project up a bit I suppose.

I highly suggest adding the ability to delete a LOD from a mesh. I imported a couple of lods, expecting this to be a problem free experience. The lods imported sideways, which I consider a bug, not user error. On top of this, I have this mesh linked to blueprints. So, without the ability to remove a LOD easily, I have to import a brand new mesh and go in and with my blueprints

I think the ability to remove LODs and also, the bug concerning lods importing sideways should be top priority right now.

Thanks, -Neil (CaptainMigraine)

Hi Neil,

There is already a feature request in our system for the ability to remove LODs. If you're having difficulty with LOD imports, please open a new post on AnswerHub as this is a separate issue. Thanks!

I note this post is fourteen months old and yet we are still unable to simply delete an LOD from a static mesh. Would it be possible to say when this will be made possible?

Regards.

No update yet, however I can say that a new bug report (UE-25591) was entered recently by one of our developers, so they believe this is a bug rather than a feature request. In either case, I have updated the new bug with a link to this post, and I'll update you when I see any action taken on it.

Hello there! Another year has passed, so I was wondering if the ability to delete LODs has been implemented and I just can't find it? Cheers ;)

Hey all,

We added the button to 4.15 to remove LOD's from a Static Mesh within the editor.

Thanks for being patient while we implemented this feature. Try it out in the new build!

Thanks,
