You don't really say if you are using a wall panel instance, but I'll assume you did. The best solution I can think of is to do it all on your own, or to edit the stock instance giving it a different name of your choice (so that if you verify ther integrity of your local files it won't be replaced back).

There's probably a func_door or similar brush entity with the sounds for moving, starting and stoping. Take a look at them and change them upon your wish.

I'm not using an instance, I'm simply using two arm64x64_interior.mdl models set to the same animation on a trigger.

Maybe I'll just use a func_door or a func_tracktrain on a piston model set, but I've never liked working with those. The tiniest placement mistake can screw the whole thing up, y'know?

Hmmm... let me know if I got your meaning:

- you are using a func_brush as a panel; due to you want the panel brush to hav good lighting on its sides, you must spawn it deployed

- that sound you don't want to hear is coming from the arm64x64 model

If this is correct and you don't really want the arms to emit any sound, just focus in the panel, don't make the arm to perform any animation. All you need to to have it in place and parented to the arm model when the player arrives there. I used sort of a convoluted trick to achieve something similar for the same reasons than you in my contribution map to the Winter Testing Initiative:

I used a func_brush (panel), parented to a func_door_rotating (because of the movement I wanted for this panel when told to open); and parented the func_door_rotating to a func_tracktrain (that nodraw cube you see in the screenshot embedded in the upper part of the panel) to lead my panel to its final place, and after the tracktrain arrived to the 2nd path_track (the inner one you see in that screenshot), I fired this output from the path_track:

- OnPass > [func_door_rotating] > ClearParent

This way, what remains is only the panel parented to the func_door_rotating. In your case, it should be the panel parented to the arm64x64 model.

I hope this example is clear, and that I understood you in the first place

Thanks for the advice, I'll remember that in the future! But I think you misunderstood what kind of panel I was talking about.
All my panel was was a simple 128x128 segment of wall, pushed out 64 units using the "64_out_straight" animation in the arm64x64_interior model.
It was completely for show and meant to make the room feel less stagnant upon entering and looking around.
You understood correctly in the point that I had the panel out originally, and used a logic_auto to retract it onmapspawn so that the func_brush would have proper lighting.
My problem was that for some reason, the last sound in the arms' animation sequences was delayed and only played once the player walked into anything related to the arms (the models, the trigger, etc.)

In the end, I just settled with using a func_tracktrain to push out a set of straight_piston models, similar to the countless func_door pistons in Portal 1.

The effect isn't as fancy in the visual nor audible aspects, but it still serves its purpose.

In the prop_dynamic settings for the panel arm there is a parameter near the bottom to "supress anim sounds" ... (I'm not at my own PC right now to check the exact name). This will turn off the embeded animation sounds. I'm not sure if you can trigger this on later (like from the trigger_look so it sounds correct when opening) or if you might need to set up an ambient_generic to play the arm animation sound... ... might be worth trying out...

Yeah, that is a good idea as well. The property on the prop_dynamic is "Supress Anim Sounds" ("SuppressAnimSounds" if you disable the SmartEdit). And I guess you could try to re-activate the animation sounds later on by firing the following output:

- OnTrigger > [prop_dynamic_name] > AddOutput > SuppressAnimSounds 0

(the param's value is a boolean one, 0 and 1... 0 disables suppresion)

Interesting, I'll give that a try sometime.
Can that same trick be used for other entity parameters that don't show up in I/O options?

Hehe... trick... Sure! I use it a lot The AddOutput output is really powerful, just disable the SmartEdit to know the 'internal' or real name for each property of a given entity to modify its value in mid-game

Quote from Crawfish on February 11, 2015, 6:25 pm

Neat, thanks!
So if I'm getting this right, the AddOutput output can be used to alter entity settings when there's not a specific I/O connection for that setting?
If so, it should be very useful for me. I get the feeling I'm never gonna stop learning new things about Hammer.
And with Source 2 on its way, I bet the secrets of its map editor will be even more powerful!
