On our 1.8.9 server we have a mod that adds a unique loot specifically to desert temples.

Now I had the idea of making a desert rftools dim to make temples more common (BoP is on the server, so deserts can be rare at times) but there does not seem to be a 'desert temple' dimlet or anything similar to it.

Do desert temples fall under another dimlet type or is there simply no dimlet for them?

Oh, found out it is case senstive. So you have to do:

/rftdb createdimlet structure Scattered

(capital 'C')
That should work

It worked, Temples are now showing up in the desert dimension, ty! 😄

Desert temples fall under the 'scattered' dimlet type. For now you can't create those dimlets on 1.8.9 though. That's still to be implemented

Ah, that is a shame, so there is no way to get temples to spawn in a RFTools desert dimension in 1.8 atm?

No not under your control. You could get extremely lucky and get unstructured dimlet generated randomly. I will soon start to implement these features but I'm currently hard at work with other stuff too

Ok, any chance I could simply edit the NBT to force-add the dimlet without the server crashing on me? :P (It is my server so I have that ability, and that unique loot really is extremely rare, only 1 in 4 temples even gets it to begin with!)

If you are admin you should be able to use the /rftdb createdimlet command like this:

/rftdb createdimlet structure scattered

Let me know if that works

The dimlet shows up, but it has the 'this dimlet is blacklisted' tooltip, and from what I gather that means you cant add it to a dim tab?

Um right. Sorry. It seems I have to do a bit more to get this to work. So for now you can't I'm afraid

I do plan an update of rftoolsdim today. I'll see if I can get this working quickly
