I don't know if this is supposed to be the case but, if you add nether quartz to an oregen and put dimlet with quarts before the oregen feature, it's supposed to work (according to everything I've read or could actually find) but, if it doesn't why would that be the case? It will not work no matter what I do, I thought it would replace all the oregen stuff with say one type, but, not even that works.

Can you describe exactly what dimlets you used?

And also what version of rftools

I used the oregen dimlet with the material before the feature. its in the default ftb infinity pack not sure which version ill find out. I also used single biome. Material none before controller or whichever ive tried putting oregen and its material first and last in both dimlet total ordering and adjacently

Oh and with single i used magical forest. Im not sure if there are other rules.

Can you take the realized dimension tab out of the builder, hold it in your hand and then shift-right click it. Then copy/paste the information you get there to here.

Okay, I will do it shortly.

I'm experiencing the exact same problem: from my console log: [10:02:48] [Client thread/INFO]: [CHAT] #m188,#L254,T407,#m561,#m529,#m195,#m207,#m562,#m189,#m203,#m191,#m200,f422,C166,B2,s365,s366,s369,s378,s388,M340,e429,S399,t486,X338,X339,X339,X339,X339,X339

FTB Infinity 1.2.1 RFTools 2.54

You have an oregen feature but you didn't specify any materials for it. You need to put material dimlets right before the oregen dimlet.

I specified 9 different materials before the feature oregen

Ah I see. Ok. I will check what's the problem

Here is a screenshot of the placement of my dimlets (Basicly the Mining age w/ added feature oregen)

Ok, I found the issue. It seems I completely forgot to attach the material modifiers to the generated world after I changed it some time ago. I will fix this for 2.60 (should be out in a few days)
