Hi,

i am creating within a geo node with copy-node packed-prims with about 200.000 instanced prims.

Later i am creating another geo node with procedural point instance procedural

So what i expect is, that at render-time the instance of the “200.000 packed prims” are rendered, which is happening, but increasing the number of instanced (the points i am scattering for the instances) my ram footprint grows and grows, rendertime becomes very high (30 min)

I will send a hip file later. Does this problem sound familiar?

i'm not the master of huge projects but maybe i can help. :-)

have you seen on the houdini manual:

maybe this tutorial will help:

whats also possible is to use the delay load shader but it's hard to tell how good it will be in this project.

please sent a simple hip file to better analyse.

PBR or Micropoly?
