Hi,

I wondering how make this trail on this png.

Tetromi
Tetromi236×241 18.4 KB

I use a shader mat for that with flipbook node and spritesheet for the animation of the trail but it doesn’t appear on the game but the material is ok.

is this the right way to use trairenderer or i have to use a another method (particle effect for example), but the trail must follow the tetrominoe.

Thanks
