Is it possible to change the blending mode of the lightmap texture to Overlay? (similar to photoshop)
So basically I have a diffuse texture and a lightmap texture.
By default, the lightmap texture is “Screen/Add” over the diffuse, or if I enable Lightmap as Shadowmap, it blends in a “Multiply” fashion. But I want to Overlay it like this:
What Overlay looks like:
As you can see, the grid fades out in the white, unlike normal Multiply.
And here is with color:
Overlay uses a combination of the Screen blend mode on the lighter pixels, and the Multiply blend mode on the darker pixels. It uses a half-strength application of these modes, and the mid-tones (50% gray) becomes transparent.
