Steps to recreate issue:

1. Create VRCFury Toggle > Turn on Slider
2. Add "Material Property" for "When slider is at 100%"
3. Set property to _MainTexHSVG (Values don't matter here, use any Renderer using lilToon shader)
4. Go into testing and find slider
5. Move slider and notice no change to the Renderer set earlier

Steps to current workaround:

1. Go into Renderer using lilToon shader and open shader settings
2. Find "Main Color / Alpha" > Open Color Adjust
3. Change any "HSV / Gamma" value to anything other than default (Only one needs to be changed, ideally any value ± 0.0001)
4. Go into testing and find slider
5. Move slider and notice change where previous test showed none

If this issue doesn't pertain to lilToon but rather VRCFury, let me know if I need to move this issue to VRCFury instead
