Godot - Simple spartial shader results too bright (unshaded, custom)

:) TL:DR When writing a custom spatial shader the ALBEDO color isn't the output color, even if render_mode unshaded is set. Long story I created a new project in Godot v3.4.4.stable.official [419e713a2] and simply added two CSGBox. For the left one…

I have two simple translucent circle sprites that I'm using as fake shadows (shown below) under some characters (not shown below). When the characters get close enough, sometimes their shadow circles can overlap - which is fine - but thanks to the…

Is it possible to add fragments outside of a 3D model's area?

In a 3D scene in Godot, I am attempting to create a pixel-perfect outline for a Spatial shader (applied after a pixelation effect to ensure the same resolution). To achieve this, I would like to modify pixels directly adjacent to the target…

Can't read a FORMAT_R8 uniform sampler2D texture correctly from within a shader in Godot

I need to pass an array of integers to a shader as a uniform. As uniform arrays are not yet supported, I'm using a FORMAT_R8 texture/isampler2D to achieve this. If I'm correctly reading the bytes from the texture, they should be in the range [0..7]…

Is it possible to test if an arbitrary pixel is modifiable by the shader?

I am writing a spatial shader in godot to pixelate an object. Previously, I tried to write outside of an object, however that is only possible in CanvasItem shaders, and now I am going back to 3D shaders due rendering annoyances (I am unable to…
