For lighting there's another route: derive the face normal in the fragment shader with normalize(cross(dFdx(viewPos), dFdy(viewPos))). The whole triangle gets one normal, there's no provoking-vertex bookkeeping, and the mesh keeps shared vertices. Check the sign once; it depends on conventions.

Kind of a rambling conversation but Hunter Biden's renaissance is something to behold. One of the bestr explanations of how the private-equity cannibals took housing $ out of reach.
It's not the boomer generation. It's deliberate manipulation by the obscenely rich.

Using dfdx/dfdy is so smart tho lmfao I will try that instead of multiple samples

it turns out on the boundary pixels, i don't have dfdx/dfdy information that informs what texture mip to sample from (since the neighbor pixel got discarded). so the texture sampler reverts back to base mip level on those pixels, resulting in a discontinuity.

You can compute normals using derivatives:
mini.gmshaders.com/p/gm-shaders...
nor = normalize(cross(dFdx(p), dFdy(p)));
Derivatives are computed in 2x2 pixel chunks, so it's best to round the frag coordinates before raymarching. Try with and without round.
Demo:
twigl.app?ol=true&ss=-...
mini.gmshaders.com/p/gm-shaders...
nor = normalize(cross(dFdx(p), dFdy(p)));

This method also works with screen derivatives:
vec3 dx = dFdx(p);
vec3 dy = dFdy(p);
vec3 nor = normalize(cross(dx, dy));
p can be in world space, model space or view space and it will return the respective normals
vec3 dx = dFdx(p);
vec3 dy = dFdy(p);
vec3 nor = normalize(cross(dx, dy));
p can be in world space, model space or view space and it will return the respective normals
