Recommendation

The shaders looks the best when they are combined!

Example :

This scene uses the following combination : Lens Distortion + Grain + TV

And this scene use this combination : Lens Distortion + Sharpness + NTSC

• Tip 1 : Sharpness is a must have if using any of the TV, VHS or the NTSC shaders for getting a more realistic retro effect!

• Tip 2 : Lens Distortion and high FOV combined can give a MTV 2000 blumbers aesthetics if used correctly!

• Tip 3 : Be careful with Grain! It can get messy really easily!

• Tip 4 : All of the shaders can go beyond their default range values, just open the shader code and just the numbers inside the hint_range() function in the variables section.

• Tip 5 : ALWAYS check the headers inside the shader you are using, theres information about compatibility, credits and licesing in there!

Instalation

To use the shaders you gotta :

1. Copy the GodotRetro folder to your project (can be anywhere)

For normal shader :

2. Just add the shader to a ShaderMaterial.

For screen space shaders :

2. Create a ColorRect and make it a FullRect in the Layout options

3. Assign the shader of preference to a ShaderMaterial in the used ColorRect.

Example :

Done! Have fun!

DISCLAMER :

• To use 2+ shaders at the same time, you gotta use a BackBufferCopy set as Viewport for each effect.

• For UI, be sure to set it above the shaders for then to be aplied for more imersion.

Examples

5 free easy to learn examples are available with the pack.
