Sorry for delay; restarted with no mods except Hugslib and Heatmap. Still getting this: http://imgur.com/a/ZYJHH ... linux x86_64, nvidia drivers

checking for logs now...

https://gist.github.com/lashtear/8bbf0fc15d93b384efc252d78852cd00#file-rimworld_log-L129 ...there's a failed shader compile above it, but otherwise looks pretty thin...

If you start a new world do you still see the same issue? Can you upload the save for me somewhere?

I've got the exact same bug... but it might be a linux thing -> linux x86_64 nvidia too !
Edit : and if it's any help, the same thing happens to the vanilla roof tool. I don't think it was always the case though - will have to check without any mod.

Hmm, I probably can't do anything about that unfortunately. The overlay drawing is handled by the base game code and the Unity Engine. There might be a bug in the way the game does that on Linux but since the vanilla overlays are simple colours it doesn't matter for the base game.

What do you see with the roof overlay?

Can you guys try the latest version? I've set the targeted .NET framework to 3.5, that might fix it.

I'm still getting the neon pink. linux x86_64 and an nvidia card.

The roof tool is working again O_o (it used to show the same fushia as your temperature tool last couple times I tried), but unfortunately the heat map still shows fushia for me as well.

Here you can see both the roof tool (in green), and your heat map tool (fushia) activated : http://imgur.com/a/etixB

When I changed from one game to another without closing the game, my new colony didn't have a heat overlay. Well, it did, but it was the other save's overlay. Still telling me about that other colony.

@Bwhyte Thanks, I'll look into that. I assume the overlay fixes itself once you unpause the game?

Same here... the roof overlay looks pink too...

PathAvoid has solved it

I swapped the behaviour of Color and GetExtraCellColor and the purple goes away, however it doesn't update the color based on the temperature.

Thanks, I'll look into that

I looked through the game code and unfortunately only the GetExtraCellColor method actually lets you use a different colour for every map cell. The Color property will only ever let you use one colour for the whole overlay. This is why I had used GetExtraCellColor.

It seems to me the developers do intend for GetExtraCellColor to be used if they wanted to have variable colours in the overlay, but since none of the ingame overlays or any mod other than mine have used a multi-colour overlay, no one noticed it's broken in Linux.

So it seems there is no way for this mod to work under Linux, unless the developers fix whatever is wrong with that overlay texture generation. I'm not sure if there's a place on the Ludeon forums where I can report that.
