Hi @chuangzu
Let’s see…
Opacity Slider for Mediaplate Video Player:
Create a Widget Blueprint with a slider to control opacity
Arrange the UI: Place the slider and a label (e.g., “Opacity”).
Bind the Slider Value to control the opacity of the Mediaplate’s material
Get the value of the slider and use it to set the opacity in a Dynamic Material Instance.
Create a Material for the Mediaplate that has an opacity parameter
Assign the Material to the Mediaplate and modify the opacity based on slider input.
Two Animated Models Tint and Opacity:
Create Materials for user and teacher models with color (tint) and opacity parameters.
Assign the teacher model a blue tint and the user model a red tint
Create Dynamic Material Instances for each model within Blueprints.
Modify the Tint and Opacity via sliders to dynamically change both parameters.
Merge Colors (blue and red) to observe overlap (e.g., purple for correlated movements)
This setup makes it possible to adjust opacity for the video and models so users can more easily compare their movement to the teacher model in real-time
