Fixture Channel Values Not Dumping to Scene?

Hi,

Super new to this and not looking to do anything terribly complicated - literally just want to use chasers and scenes to light my D&D table.

My problem is that when I try to dump channel values to a scene, the scene only seems to receive the dimmer channels and none of the RGB, strobe, or mode channels.I'm absolutely stumped, as I believe I setup up the custom definition correctly. I can't seem to find anyone who has had this same issue.

If it's relevant, I'm using a USB to DMX adapter and the uDMX libusbK driver from illutzmination, and my fixtures are generic PAR36 cans from Amazon (6 channel RGB). Not sure what step I might have missed to cause this to happen. Everything seems to works as expected in manual.

Apologies if I'm misusing terms or vernacular; again, super new to this.

Thanks in advance for any help!

Welcome to the community,

To understand you better... you set some values: where do you do that? On the simple desk or directly in a scene?
And now you use the DMX dump function? Did you set the correct values for which you want the dump? It seems in your description that the RGB channels are not selected.
Please have a look here explaining what DMX dump does: https://docs.qlcplus.org/v4/main-window/dmx-dump
In my personal opinion, the better way is to create looks directly into scenes. Create a scene, add the fixtures involved, select the channels you want to set, and give them a value. The 'Copy to all' option is also very handy and quick. You set a look for one fixture, and copy to all does the rest.
Put that newly created scene inside a chaser, et voila.

Thank you; hoping to learn a lot!

I set the values on the simple desk. I then used the Dump DMX Values to a Function button in the top right. I have Dump All Channels and Add to: Chasers selected. When I go to the Functions tab, I see that it has created the scene under the Scene drop down, but selecting the scene does nothing with the lights themselves, and selecting the individual fixtures at the bottom of the screen shows me that each fixture only has the dimmer channel available. Screenshots attached.

Manually building the scene and adding fixtures yields the same issue. It's as though it doesn't recognize the other channels exist, so I feel like I've missed specifying that somewhere.

I hope I've been clear; again my apologies for any misuse of terms.

.... as I believe I setup up the custom definition correctly.
Sorry to disappoint you, but the problem is in your Fixture definition.
For a 6 channel PAR your Simple Desk should look something like this:

In this case i used the Showtec Led Par 56.
I suggest you open this Fixture Definition in your Fixture Editor and use it as an example.

It is important to understand that people read (and understand) descriptions, but programms (like QLC+) need Presets, Types, Ranges etc. :)
You could also have a look at the tips overhere: viewtopic.php?p=73763#p73763

Thank you both for your help! MichelSliepenbeek nailed it; I had failed to define 6Ch mode. Once I set that up, everything clicked and I'm off to the races.

Cheers!
