I am trying to generate an image for a tomogram (1.6G).

It can run through if I use a value that produces 33651412 triangles. But if I use my target level value, it will need 825273846 triangles and it threw the following error:

(I am wondering if this is an edge case and how should that be dealt with if I want the image at my target level value?)

Many thanks,

Zhe

PS: MacOS 11.01.1 with ChimeraX 0.9
