Thanks all, I’m fairly certain the origin points and transformations are correct, as most of the grass GN instancing is fine, there’s just a few floating “artefacts” for want of a better term. They’re not even entire grass clumps, just small sections of geometry. Blend files are in the folder below, it’s most obvious in the early parts of “AstrayModel_2” where the camera moves through the trees between frames 1-100 (there’s a png of the rendered result), but it happens everywhere to some extent. I’ve included all the asset library files as well just in case.
