Romfly

I've a problem that I'm currently unable to find a solution... I play with KSP 0.90 and all the engines trails and smoke effects are made of colored -even if the dominant color is white- big pixels. Did I miss something obvious such as "hot rockets don't work with KSP 0.90", or "install ...... first" ? Thanks a lot for any answer and good flights ! Romfly Edit 1 : Okay, so installing texture manager seems to have fixed the problem, maybe it will help some others with the same problem
