So now basically I've created a new sprite via script and I need to assign a shader and manipulate it how can I do that please?

Thank you very much in advance again

This is what I have but it doesn't work

var mat = CanvasItemMaterial.new()
const skew_shader = preload("res://shaders/shearing_shader.tres")

'----inside function

mat.set_shader(skew_shader)
sprite_p.set_material(mat)

Yeah, IIRC CanvasItemMaterial is for the default builtin shader.

@TwistedTwigleg said: Maybe try using a ShaderMaterial (documentation) instead of a CanvasItemMaterial?

I 've been trying even another way but nothing, It doesn't produce any result, no errors but even no result

@Megalomaniak said: What is your actual shader like?

it is about image manipulation. But it works , it doesn't when just called by this script

The result of the shader is supposed to be applied/written to an image via the script then? What node specifically is holding the image buffer? A viewport?

Hi I tried something like that and it works, the shader is assigned on sprite via script Hope that's help

script on Node2D

func _ready(): $Sprite.material = ShaderMaterial.new() $Sprite.material.shader = preload("res://test_shader.tres")

shader test

shader_type canvas_item;

void fragment() { COLOR.rgb = vec3(5.0, 0.1, 0.2); }

Yes but as you have written I cant understand.
basically I have this function in loop

func render_(): var sprite_ref = $AnimatedSprite HERE I NEED TO ATTACH A SHADER to this sprite
