Inverting normals can come in handy for shaping interior spaces more intuitively. #MudBun #GameDev #MadeWithUnity #VFX

GPU-based auto-smoothing was fun to implement. Adjacency is constructed by spatially hashing & adding coinciding verts to a shared list. Then each vert's normal is updated to be a weighted avg. of similar normals of verts in the same list. #MudBun #GameDev #MadeWithUnity #VFX

Take 1 was in 2021, and this time I have some ideas to make it more performant.

Ray-marched surface, take 2. Not sure why it's so much brighter than regular meshing. Even dual contouring can't beat this because it's the ground truth. Voxel density affects the proxy mesh complexity but doesn't change the visuals. #MudBun #MadeWithUnity #GameDev #VFX

Another one. Blending between surface nets or dual contouring and intermediate dual quads never gets old. The mesh is constructed & animated by sampling triangle noise with scrolling spherical coordinates. #MudBun #GameDev #MadeWithUnity #VFX

Another demo of blending between surface nets and intermediate dual quads. #MudBun #GameDev #MadeWithUnity #VFX

Quick & easy way to get dithered transparency to look more convincing on overlapping transparent objects: throw unique object hash/ID into the mix for noise seed. #GameDev #MadeWithUnity

Transparency blend & splat size blend. #MudBun #GameDev #MadeWithUnity #VFX

Sometimes it's desired to jitter splat orientation. With high-frequency noise though, the normals might appear to be too noisy. A blend back to the original normals can help, in the same vein as normal transfer techniques for foliage in games. #MudBun #GameDev #MadeWithUnity #VFX

More documentary of the shelved experimental ray-traced voxel render mode. Splat size was used as a proxy for rendered voxel size. Had to speed up the video to fit within bsky's limit. #MudBun #GameDev #MadeWithUnity #VFX

Sparse hierarchical voxel nodes are used to narrow down which voxels to generate triangles for. I use branching factors (8, 8, 4), so one highest-level node, or "chunk", contains to 256 voxels. Only a node that intersects the SDF zero surface is further branched. #MudBun #GameDev #MadeWithUnity #VFX

The surface nets & dual contouring algorithms both involve an intermediate step that produces voxel quads and a final step that offsets vertices towards the SDF zero isosurface. Naturally...I'd want to try blending between the two steps. #MudBun #GameDev #MadwWithUnity #VFX

Demonstrating varying voxel density, render modes, and splat options. #MudBun #GameDev #MadeWithUnity #VFX

Using each splat's center to sample a 3D Perlin noise gradient for offset creates this interesting effects as the sphere brush is moved around. #MudBun #GameDev #MadeWithUnity #VFX

SDF modeling is cool because you can just move the mouth around like this. #MudBun #BoingKit #GameDev #MadeWithUnity #VFX

Overlay blend mode for dye brushes. More artistic controls. #MudBun #GameDev #MadeWithUnity #GameDev
