RealityKit experiment #71
(gist in the comments)
- Loads mesh & texture from USDZ
- LowLevelMesh verts use float4 color+alpha in uv2
- ShaderGraphMaterial blends texture with uv2.rgb, sets opacity from uv2.w
- Metal Compute Shader animates uv2

Offset the UVs of your caustics texture to get a cool chromatic aberration effect 🌈
uv1 = uv + (split, split)
uv2 = uv + (split, -split)
uv3 = uv + (-split, -split)

additional uv maps to sculpts for makeup overlay layering cause they'd just be identical to UV1/UV2?

I baked big AO and Bent Normals to use it for the background in UV2.

been looking into that and it seems possible. LightmapGIData gives all APIs to set our own data. UV2 unwrapping is separate from baking so doesnt need porting. I'll need to port atlas packing though but it should be fine

I made a mistake in claiming that Godot doesn't support area lights for lightmapping. Turns out it does through emissive materials! However, for this to work, not only do light *receivers* have to have UV2 unwrapped, but so do the light *emitters*! This is what I was missing. 🤦♂️

Planting flowers. I use UV2 to have two color variations on one single mesh (the red and yellow flowers).

the reason it's separated like this is for UV unwrapping on the UV2

I need to praise @quaternius.bsky.social assets. His geometry makes it so easy to work fast! My materials us UV1 for PBRs (made in @rodzlabs.bsky.social's Material Maker) and use UV2 for details/edgewear (using DreamUV atlases). #GodotEngine #Blender #GameDev

Le maire et l’organisateur ont négocié un protocole d’accord qui laisse la quasi-exclusivité des frais au producteur du spectacle. Malgré les coûts engagés, David Hardit se félicite «de ne pas avoir plié» face à la municipalité.

if you copy your UV1 over to your UV2 on these, you'll end up breaking your facepaint, company crest, and legacy tattoo among other things

JUST!! be aware that blender labels these differently from textools.
TT UV1 = Blender UV0 (Main UV map)
TT UV2 = Blender UV1 (UV map used for extra shit like crest, legacy mark, facepaint)
UV3 / Blender UV2 is unused

using the vertex colors (and counting edges ) to identify the loops of segments. (which will be the base for railing generation)..
I can not express how much easier is when you never have to think about UVs, texture distortion and are used to using vertex colors and UV2 as just extra data.

Godot gotcha: So if in Blender you merge two meshes and end up with two UV maps, Godot will treat this as UV2, and will include it in light baking. This completely ignores the light baking import setting. 😩

Like so: the base textures have UV1, and another texture with transparency is used for expressions on UV2, blinking and some speech. Most game engines reserve UV2 for lightmap uvs though
