Koyaanis

hey guys, i didn't read everything on here, but i have some problems with the mod. some of the parts i see in the video are not in the mod, so i looked for more. i found the Infernal_Robotics_Model_Rework_-_Core_Pack-v01b and Infernal_Robotics_Model_Rework_-_Expansion_Pack-v01b but those parts become black and there are still some missing. am i doing something wrong? i use KSP 1.0.4 IR: 0.21.3
