Hi Michael,

Success!!!

Setting the FileLoadThreadLimit=1 in moi.ini was successful in stabilizing the Styles (colors) from Andy's file COIA-CORE.step, when Opening the step file.
Opened Load Styles were consistently the same, for multiple trials...

It also seems to stabilize the Styles (colors) when doing step file Import. (On the first try, it seemed off, and doing a second file Import added the stabilized version below the first import...)
But additional trials of Import of step, after closing and re-opening MoI were the stable colors. (Unless there is some caching going on???) Additionally, doing a second Open of the Step did NOT add any additional Level Styles.

(My previous setting was ...Limit= (followed by nothing, no number).



I assume that the above Styles (Level #'s styles) are the "correct" Step colors???

Thank you Andy.

- Brian

ps The nearBlack rgb of 1,1,1 is still needed for Level 1
