This has been supported as of 1.3.0-5

Then I'm missing something in this config. Here's a re-homed KSC on Duna:

Body
{
	name = Kerbin
	cbNameLater = Duna
	cacheFile = AlienSpacePrograms/0Miscellany/Cache/Dunakerbin.bin
	Template
	{
		name = Kerbin
		removePQSMods = PQSLandControl,QuadEnhanceCoast,VertexHeightMap,VertexHeightNoiseVertHeightCurve2,VertexRidgedAltitudeCurve,VertexSimplexHeightAbsolute
		removeOcean = True
	}
	Debug
	{
		update = true
	}
	Properties
	{
		displayName = Duna
		displayname = Duna
		Biomes
		{
			Biome
			{
				name = MidlandSea
				displayname = Midland Sea
				displayName = Midland Sea
				value = 0
				color = 1,0.568627477,0.00784313772,1
			}
		}
	}
}

Note that I have a 'short name' without spaces and a displayName (and displayname) with spaces. I want the name with spaces to display.

And here's a science report and KerbNet image:

The more complete example is here.

What am I missing to make biome names display correctly in KerbNet? And while I'm at it, I'm also missing something with gender because the crew report reads, "from MidlandSea of a Duna," instead of, "from Duna's MidlandSea."

Maybe if Kittopia-tech was updated for KSP 1.3.0 we could get fresh dumps and working examples.

Are you sure kerbnet can display the displayname ?

When I go to an unmodified stock world with Kopernicus running, such as Ike in this configuration, biome names show up in KerbNet.

no idea, as far as I can tell the name is set correctly

the issue here is that the changes to the biomes are only applied if the biomeMap field is parsed

(I suppose)

you didn't post all your configs so that's my best guess

smh

apparently displayname is set from localizationTag

I'll change that and submit a PR later

this should be solved with #238

the issue here is that the changes to the biomes are only applied if the biomeMap field is parsed

I just posted a short example. The full example is in the link that followed, and here's another link to it.

I'll take a look at a test build based on #238 if you'd like, after six hours from now when I'm off work.

this issue has been solved, it will be included in the next release
