I wanted to leave this as a comment on the main mod, but it got too long, so here it is instead:

I figured I would let you know, given the few times I have heard people mention how frequent Titanium, Beta and Alpha Poly materials show up as a stuff-material for anything stuff-able (particularly weapons/armor). I believe the fix for preventing this from happening is just adding a <commonality> tag to the material thingDefs in the GT_Resources.xml file. This goes within the <stuffProps> tag, and I just tossed it above the <color> tag.

For example, I changed Titanium to <commonality>0.025</commonality> - and for reference Steel is at a 1.0 commonality, while Jade sits at a 0.05. I figured given the supposed high-tech requirements to craft it, this made sense it would be rarer then Jade. For Alpha and Beta Poly I just changed theirs to be 0.0, since I doubt anyone should have those apart from the Orion guys. In my initial testing, this appears to have worked and prevented it, but I have not done extensive tests yet, just continued my regular play.

Finally, one last thing I noticed, is that all of the research for the mod is at the tech level of Industrial. You might wish to change that to properly represent the tech at the Glitterworld level. I hope this helps, and good luck with GlitterTech 2! It will be interesting to see it when it comes out!
