Is that where Nanite came from?

No. Hoppes work mostly operates on individual triangles, either by collapsing edges progressively as shown in quoted paper, or even in continuos ways where vertices move gradually towards a collapsed state.
Allthough this had initial applications, e.g. for t…

I've used progressive lod only with storing clusters directly in nodes, not groups of clusters.

I'm not sure how do you want to work with group of clusters there (or how that works in general) - the problem with DAG for LOD is that once you include single child of a parent - you have to exclude ALL …

I'm developing a Hierarchical LOD Nanite-style system using meshoptimizer. I'm having troubles with how to create a local index buffer from a group of merged meshlets. Is there a correct way to create a local index buffer from a group of merged meshlets? Do you have any suggestions or advice on tha…

@cgrant Many thanks for the reply, I will see the link that you sent to me 

I managed to get the back face shadow map generation working relatively easily…indeed, it does address the LOD transition shadowing issue. Of course, the shadowing itself is not working perfectly as I have various depth biases to (re)adjust/invert (I have different depth biases per shadow cascade t…
