Hello, I created grass with the Pivot Painter script which bends away from the player. The grass only bends away where the player is but now I want the grass to stay bent for some time, like real grass does when you run through it. I have no idea how i can do this. Can I do this in the material editor or do I have to create a blueprint for this? Sorry for my english and thank you in advance.

Here you can see my grass I created: [[UE4 | Pivot Painter grass - YouTube](https://www.youtube.com/watch?v=br8iKGvfLY8)][1]

Here you can see my material:

Canvas Render Target 2D is the option you are looking for.

> **[Canvas Render Target 2D](https://docs.unrealengine.com/5.1/en-US/BlueprintAPI/CanvasRenderTarget2D/)**

> Canvas Render Target 2D

Though you’ll need to paint three colors instead of one like in this video but it should give you an overview what to do:

Ok, thank you I will try it. But is there no possibility to slow down the animation of the grass because with the Canvas Render Target I can deform something but I have no Idea how the grass moves back after sometime? Sorry for these silly questions I am new.

For the grass to restore, the blend mode needs to be modulate (it multiplies the values), position (0.0) and the color something like this: 0.8, 0.8, 0.8. That way every time you call this function it will multiply the color values by 0.8 lowering them. Call that function for example once per second with a delay node and viola! Your grass is restoring =) you can make the color 0.9 to make the process slower.

Ideally you want to try and replicate something like this.

How I have it set up is, I have one more Sphere mask that follows the player with a slight delay and keeps the grass bent.

Thank you very much! I created new interactive grass without Pivot Painter. I also had the idea with the Sphere mask that follows the player but I have no idea how i can solve this.
