Thank you for the very detailed answer. I also had the idea that the SL-fans are still too new and are therefore not included in the internal profiles. On the other hand, the Corsair website uses ICUE to advertise the lighting effects.
Corsair should definitely improve his profile, because these effects shown on the website were the reason for me to switch to Corsair in the first place. Due to the lack of knowledge of how it works, I couldn't know that the internal profiles would not work with the SL-fans.
The fans light up after importing the proposed Division 2 profile. But Division 2 was not the problem, the SL-fans are lit here (except that in the game itself, if you walk through the area, nothing or little happens to the lighting).
Far Cry 5 or Exodus profiles, on the other hand, have no fan lighting after an import.
Unfortunately I have no idea how to add SL-fans (with the same effects and they are script controlled?). I will probably wait and hope. Thanks again for that.
