Very nice job of explaining this with lots of clear examples.

Awesome thanks for the explanation and the tips, now I am converting scenes to Nanite and noticing the memory savings. Cheers

Thanks for your valuable effort to explain nanite technology, have a nice day!

great video, thanks! regarding draw calls, the optimisation you suggest they are using makes sense. It has always been frustrating that engines do not automatically combine objects of the same meterial into a single draw call unless they are "static" (Unity at least has always combined static objects with the same material and model into a single draw call, it called it dynamic instancing). I have in the past written some stuff to render multiple objects using a single draw call (by moving parts of the mesh on the GPU side) but it has always worked against the "design" of game engines such as Unity and UE.... I wonder if they will take the draw call optimisation and apply it to dynamic "normal" objects :) (that would be a great win for low power devices)

When I choose viewmode for nanite triangles it just dims the default lit. I don't see any nanite triangles. Any ideas?

How can I tell if my runtime storage is set to my ssd?

this video is amazing , and i added to my good tutorials playlist which is hard to get into, one question so i noticed the light leakage problem while working in my first project, and since it was my first project i thought the problem was with me and after hours of trying to find out where the light was coming from i just built walls around my scene and gave the walls the same material as the ground, like u did my question is - should i convert those meshes to nanite to reduce cost or will it make it that they will have light leakage as well?
