When changing the brush's alpha at runtime causes only the last or the latest painted brush to simulate fluidic effects (see screenshot) (Modifying scale works fine)
(Note: How can I change the width and height in scale separately?)
(Note2: Changing the alpha in HeightFluid changes the alpha of all the painted brushes ☹️ )
This is how I change alpha in the Update() function
//vars
public InkCanvas inkCanvas; //set in inspector
private static readonly System.Random random = new System.Random();
float dampedAlpha;
//functions
private void Update()
{
if(Input.GetMouseButton(0))
{
var ray = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit hitInfo;
if(Physics.Raycast(ray, out hitInfo))
{
dampedAlpha = Mathf.SmoothDamp(dampedAlpha, (float)RandomNumberBetween(0f,1f), ref vel, Time.fixedDeltaTime);
Brush tempBrush = brush;
tempBrush.Color = new Color(brush.Color.r,brush.Color.g,brush.Color.b,dampedAlpha);
inkCanvas.Paint(tempBrush, hitInfo);
}
}
}
private static double RandomNumberBetween(double minValue, double maxValue)
{
var next = random.NextDouble();
return minValue + (next * (maxValue - minValue));
}
Steps to Reproduce:
Attach "InkCanvas" Component to plane.
Attach "HeightFluid" script to the plane.
Uncheck "Performance Optimize" in HeightFluid script
Change Properties of brush to:
Color Blend Type = Alpha Only
Normal Blend Type = Add
Height Blend Type = Use Brush
Create a custom script, modify the alpha values in Update() and paint.
