Create fillable SM/Material for mobile game on UE5

Job ID: 36359795

Budget: $30 – $250 USD

Need to make the following system:
There is a 3D Static Mesh in the shape of a triangle with a rounded side. It can change its length (From O to AB) and width (From A to B). In normal mode, it has the form (TI_F.png), that is, 2 lines along the edges. It has a variable C (for dynamic material, the limit is from 0.0 to 1.0). It is responsible for filling the triangle. When C = 1.0, the triangle has the following shape (TI.png).
The shape is translucent in color (color and opacity are set in the material)
This is necessary for mobile devices, so optimization is important
