Hey guys I was just playing around with instancing teapots. Went to render them, and they rendered fine. Added another camera with a different angle, and I get this error message. Here is a hip file. I'm using the latest daily build. Cam 2 renders fine, though cam 1 seems to always crash. Thanks in advance I thought it might be my lower end computer, but why would it render for one camera, and not the other?

I thought it might be my lower end computer, but why would it render for one camera, and not the other?

It's the difference in tesselation. /obj/cam1 is closer to the teapots, so there would be more triangles per teapot, which will consume more memory.

For example, in your scene, rendering with /obj/cam2 uses 1.18 GB of memory, while rendering with /obj/cam1 uses 3.57 GB. On a 32-bit system, this will easily blow your memory limit, causing a crash.

If you reduce the shading quality to 0.5, the memory requirement drops down to 1.68GB for the /obj/cam1 render.

Thank you very much for the explanation halfdan. I did not realize this was the case. Looks like I will have to do as you suggested, as well as try to upgrade my computers memory. Thanks again, and I hope you have a great weekend
