- You should run this script from embedded python interpreter!
- Not compatible with Source 2 Filmmaker.
- Works with all models.

Just subscribe to this item!
Additionally, if you're familiar with Python - invoke Directional Scale Patch's main() from sfm_init.py so it will be executed automatically on startup.

To create controls, execute Directional Scale Controls from "DAG Utilities Menu" in dag (bone) submenu.

To display the scale changes, you should execute Directional Scale Patch script from Scripts menu (navbar) every time you restart SFM.

Problem: Applying this script on multiple ancestor dags may cause FPS drops when posing their childs. E.g. applying it to spine3, spine4 and neck will cause some lags when posing the head. This happens because SFM has retarded expression handling in slider controls. However, it doesn't affect completed animation and happens only when you directly change pos/rot from the interface. Dags without such ancestors or from any other "Animation Set" in the session won't cause the FPS drops. Not really problematic until you want to rescale every bone in the model with poor CPU aboard.

Solution: This script has an unused function create_attr_slider_simple which creates slider without the use of an expression. Just swap function names with original create_attr_slider. This slider type, however, is limited to [0, 1] range and not remapable. To bypass this limit use Facial Flex Unlocker (which unlocks not only flexes but all sliders in general) or Graph Editor mode — not UI-friendly, but lag-free.

---

Problem: In order to minimize the effect from previous issue, I simplified the expression and by that sacrificed "Remap Slider Range" functionality.

Solution: Actually, with the use of master-scale you can stretch the dag up to 64 times in every direction, but if you want more, or, for some reason, negative values — use Facial Flex Unlocker or simply Graph Editor mode.

---

Problem: Directions on different bones even of single model are oriented differently. X may be Y or Z can be X in relation to the world.

Solution: Presented X Y Z is actually local bone orientation. That's not a bug.

---

Problem: Jigglebones (if there's any) of attached models (e.g. hats) will slightly distort after Undo (CTRL+Z) on scale controls.

Solution: Just hide-unhide the distorted model to normalize it.

---

Problem: Under some conditions RGB position/orientation controls (as well as skeleton) can be stretched and hardly usable. It started to happen after we added support for locked bones and attached cosmetics. Why? Because these 3D-controls are the very same kind of attached objects as hats.

Solution: We're still searching for a way to separate that effect. It seems unreasonable for us to revert the update, so you can change it manually if you want. Just comment these two lines (add # at the beginning):

This will prevent the attached/locked elements from rescaling. If you still want them, don't comment these lines, but instead adapt to use Graph Editor mode or "yellow circle" controls.
