all my attempts to reduce the poly count of giant million+ poly meshes have led to my computer freezing up and blender crashing. It has tools that pretend they can do this, but they just fail epic.
the only work around i’ve found is to hand paint a few “inches” at a time and then dissolve 100-1000 faces at a time, which can still take a while, but 2 minutes x 1000-10,000 for a million-10million face mesh is insanity. People are coming in with insanely dense (and largely undeserved density) scans but none of them are useful without a million dollar computer. Is there no better way?
one section of the last mesh i worked on was FLAT, and it had like 30,000 triangles! Please help stop this madness.
