I've updated to add new recipes with Titanium ore + Vulcanite Block smelting. Different recipes depending on whether you are using Space Exploration or SE/K2 combined. In the latter case it uses enriched titanium. Saves on ore at similar rates to those base mods either way.
There was also a strange compatibility issue in 0.5.x Space Exploration core fragment generation that I've fixed. Do please let me know if you run into any issues!
