I've adding this to the 4.6 merge queue since it's an enhancement. But feel free to change if you see this going into 4.5 yet.

Decal, Sprite{2D,3D}, and VisualShader used _validate_property() to hide related properties before. Those logic redundant now and can be removed.

Looks like there is failed check in a class I didn't modify?

Rebase just in case; I assume that was a fluke

Did some local testing & it looks like removing _validate_property from Decal was the culprit. Perhaps that should be reimplemented, but with just the || p_property.name == "distance_fade_length" conditional removed? Or the logic they previously hid should be integrated directly, if possible

Seems to me that sorting_offset is not supposed to have default value in VisualInstance3D. It's even defined incorrectly, the binding uses DEFAULT usage, but then overwrites it in _validate_property() unconditionally 🤦‍♂️

I went ahead and fixed it.

Thanks!
