Your animations may vary, but the main idea is using "idleend" animations in Hammer. The idle powerup animations are horribly off-grid in Hammer, and are therefore impossible to correctly parent the brush to. By using this method, you can align the brush to the panel face in Hammer on-grid, but when the map spawns, it will move into an idle powerup animation, with the brush perfectly parented.

1. chose "setParentAttachment" instead "setParentAttachmentMaintainOffset" with a logic_auto
   and 2. place the brushes NOT on the arms but aligned in the wall (sometimes 90? rotated)
   and 3. chose any idle animation as default animation

you would get a thing that works. In fact, I'm very sure I've done that before.
(That would mean Skotty said it just the worng way around)

Actually, yeah, I'm pretty sure that works as well. Personally, I prefer my method because I feel like it's more organized, but whatever floats your boat I guess.

Also, the anim_wp\room_transform\arm64x64_interior_animation isn't showing up in the model browser or in Hammer at all. The file is in the model browser but when I click on it it just shows an empty grid where the model should be. It even shows all the animations under the sequence tab.

If so, next time first leave the panel straight, create the func_brush and then select both to drag them in the angle you want.

@Brainstone: I tried changing the angles and zooming in and out with no avail. Also, when I set this panel to the world model and place it in the world, it appears invisible. I can move it around, but it just appears invisible.

Man, the animation models aren't intended to be used in game, they are simply the animations of a model, you should be using the model arm64x64_interior instead

I'm not sure if you people are misunderstanding me or if I'm misunderstanding you. I'm using idle animations for these panels and they aren't moving, so I don't think it's a problem with parenting. It's just very very difficult to drag the brushes to the perfect angle against the wall panel using the circles and double clicking it.

I think it's a misunderstanding on your part, though my answer was, admittedly, a bit off. The tutorial on the VDC will still work, but you skip the last step which involves causing the actual animation

oh, and make sure you don't use the model with "_animation" at the end, that's not meant for actual panels.
