Control static fan colors individually in hardware lighting?

Hi,

 

As a Linux user, I have to rely on hardware lighting (using a Windows VM just to change settings).

 

Is there a way to control the fan LEDs individually in hardware mode? Selecting them by holding CTRL doesn't work there. I can only set all fans that are on the same hub to the same color.

 

Am I missing something?

 

If iCUE currently can't do this, is there a chance of this feature being added in the future? Because other lighting patterns like visor seem to already proof that hardware mode is capable of addressing each LED of each fan individually, so I guess individual static hardware lighting is something that could be added without replacing any hardware...

No, you can only choose 1 of those presets we talked about earlier and it is applied to the entire channel. Without the software to manage it, you are left with the pre-programmed effects and not individual fan customization. I don't think this is something that will change on the current generation of hardware. It would require updated controllers, MCUs, etc. to be able to handle more processing requirements. When this all started, there was no hardware mode at all - just rainbows. Some progress has been made.

The only way you could get your different effects is to use different RGB hubs for each set you want a different effect. So if you bought 6 LL in two triple packs, you could put the 3 front LL on RGB hub 1 into channel 1 on the Lighting Node Pro and then the interior 3 LL on RGB hub #2 and channel 2. This would allow you to do something like color wave front and static white interior (or any of the other presets).

 

The other thing to be aware of is the “previews” of HW Lighting shown in CUE when in that tab are misleading. That is the software version of the effect. The hardware version timing is already written to the device. Effective speed and pattern will vary with fan type. So visor may rip through a stack of 4 LED ML fans at medium speed, but take an eternity to make it through 6 QL at 34 LEDs each. Other effects like Color Wave are quite different with the software version generating one color wave per fan and HW Mode one wave per set. Rainbow Wave is listed, but it is mislabeled and is really something far less complex in HW Mode.

 

Because of this, you’ll want to quit CUE app from the task bar while still in your Windows environment to check how it looks before rebooting to the other OS. HW Mode usually offers some surprises.

Thank you your your detailed explanation!

 

Yes, I get that you can set individual HW lighting per hub or per node core.

 

About the preview, yes, I noticed that something might be wrong with it because the animations seemed to "stutter" while iCUE was running and got smooth after I quit iCUE. Maybe this is caused because I'm using a VM with USB passthrough to access the node core. Anyway, the HW presets work fine and I can change them using the Windows VM. That's all I wanted.

 

About that individual static hardware lighting: As you said the presets are stored on the hardware (I assume on the node) already and merely selected by iCUE, they must have gotten there somehow. You said that HW mode was patched in later as the nodes could only do rainbows before. That's why I assumed if presets on the node can be altered by software (update), in theory, iCUE could create a custom preset out of my individual static settings, store it on the node, and run it in HW mode. Implementing this might be a huge effort though...

 

I didn't mean this as a complaint against the product or your reply in my other thread, but rather as a question if I'm doing it wrong. The last part was meant as a suggestion, like if according to my understanding, not hardware but software is limiting the possibilities, software could be extended to allow for even more customization.

We may be heading that way. The last generation of RGB stuff was thumb remotes. Now we are onto software controlled D-RGB, but the marketing mechanic was 'buy the fans, get the controller for free'. That creates a need to keep the cost down. It seems like the logical next step is to make more sophisticated controllers for those that want them. The keyboards work the same way with either 1 preset lighting or up to 5 static/wave/ripple/gradient custom effects. They just released the first keyboard (K100) that can save full software profiles to the device. It has an upgraded MCU compared to its predecessor, but a new price to reflect that as well.
