I'm playing project Ozone 2 and for a completely blank dimensional tab I get this kind of cost. Any idea?

That's because in PO the pack is configured so that random features get the full cost. Not a bug in rftools dimensions but just how it is configured

Hmmm. I've seen other people's play throughs that didn't have this problem. I'd hate to think it's just me but if that how the mod pack is set up i might as well cheat on a creative one...

That's because the dimension is random. It is possible you got some expensive random features that others didn't get

I understand that but even with the blindness dimlet that is supposed to reduce the cost by 400% the dimension was costing rough 2 million rf/tick. Maybe I'm insanely unlucky/lucky with my dimensions. Ive tried 3 variations in total. All of which have cost well over a million rf/tick to maintaine. I have use this mod b4 and this is my first encounter with this kind of thing. The dimlets are amazing btw. A lot of fun can be had with them.

I haven't played this pack myself but I have heard you can easily get crazy amounts of RF generation in it. i.e. everything is pimped up basically

I can't say I'm at that point. Our big reactor only generates half a million rf. Thanks for the help
