Some general tips that helped me with the material gathering:
Doing the above, I gathered all raw materials i needed to do my planned upgrades for all of the engineers in a single afternoon.
- Leverage Dav's Hope for manufactured materials
- Leverage the Jameson Crash site and/or Bugkiller for Encoded materials
- Use a site like EDDB to do targeted planetary landing/gathering for the Raw materials you need. Go after planets that have decent % of the material in question AND volcanic activity, then gather only at the Geological signal locations. Density of materials is much higher that way.
- Specifically target gathering the G4 Raws in the 'rows' that you need materials from rather than worrying about gathering all of the G1-3 of them, then just trade at material traders for any of those G1's to G3's that you did not just get while working on the G4's.
Ok, I'll do some Dav's Hope and Jameson Crash site and Anaconda crash site relogging. Sounds like fun.
I would be so much happier if raw materials were also mission rewards.
This would be so much better if they made sure that you could get what you need just following whatever career path you've chosen.
