I followed tutorial for hdr in 2D and it works great until I need to add something brighter than current most bright sprite e.g. sprite on the left have maximum value of modulate, I want to add something brighter

To decrease sprite brightness I can use modulate property but how to increase it?

Wow that looks awesome. Could you share the tutorial you watch to create that effect, please.

Since modulate multiplies the colors, there is no way the render gets brighter than the original sprite. You have two solutions:

  • produce a brighter version of the sprite in any image edition software
  • use a shader

If you want to use a shader, here is a sample shader that should do what you’re thinking of:

shader_type canvas_item;

uniform float bright_amount;

void fragment() {
    vec4 c = texture(TEXTURE, UV);
    c.rgb += vec3(bright_amount);
    COLOR = c;

Thansk for answer. I’ve found that shader solution is more flexible in this particular scenario, also to be able to apply material to a packed scene I needed to set Use Parent Material property on every node in chain
