I found such an example of mashstabirvoaniya primitives in the topiq.

How can this be done? P.s. You also need the primitive to not follow the camera ---

Hi @Victor_Johnson, Does this need to be done with the Primitive API, or would it be possible to use the higher-level Entity API? ---

I think he has the same problem as me. To display a large number of primitives, you need to scale on the shader side to avoid drawdown. I am also looking for such a solution. ---

I need to use the primitives specifically
