Map check warning: minimapworldunitsperpixel

Using UE 5.1 (no specific tag available yet it seems)

At various times when saving/building (I am very new to this) a map check warning is shown to me, with a link to documentation that also doesn’t appear to exist yet.

Life on the bleeding edge!

The warning reads "WorldPartitionMiniMap_UAID_B42E994DC454684B01_2046932663 WorldPartitionMiniMap_UAID_B42E994DC454684B01_2046932663 : Expect a low quality minimap : effective world units per pixel is high (50,000). " and is appended with a link to Map Check Errors in Unreal Engine | Unreal Engine 5.1 Documentation which has (at time of posting) no information about the warning.

I have searched unrealengine.com (forum and dev), gamedev.stackexchange.com and Google for the warning phrases and found absolutely nothing.

Can anyone tell me what’s wrong?

Hey there @FredGandt! This warning is for the world partition minimap located in this little nook.

It’s basically saying that the resolution for the minimap itself is going to be poor due to the current scale of it. The minimap itself is a virtual texture, so when it’s built if it has to be absolutely massive. Try rebuilding the minimap here and see if it still occurs.

Hello and thank you for helping me SupportiveEntity :slight_smile:

I tried the Build Minimap as you’ve illustrated, and Map Check still gave me the warning.
I then tried Build All Levels, and Build HLODs when prompted, then retried Build Minimap, and Map Check still gave me the warning.

Is it possible the warning is, as it says, just to “expect a low quality minimap [and tough luck!]” i.e. unfixable?

My only real concern is that the actual level is bad in some way that I should learn to address now before getting too far ahead (it’s very easy to learn bad habits, but very hard to break them), but if it’s only the minimap generation, that will only affect my editing - right?

I did just notice a hole in the landscape :astonished: which might be related?
I have no idea what I’m doing yet :laughing:

It’s possible! It shouldn’t effect gameplay unless you were to use your WP minimap as an in game minimap. Then you’d have to figure out how to correct the resolution issue. I’ve made 60km test maps in WP and haven’t gotten the warning so it’s somewhat odd.

Maybe I switched a setting off or on or something without realising. I will build a new level the same way and see if the same warning comes up. Luckily at this point in my learning, everything I do is disposable :laughing:
If nothing else; I just learned that we can use the WP minimap in game :+1:
I will report back about the warning when there is something definite to say about it.
Thank you again @SupportiveEntity :slight_smile:
