Hi Christopher, for some reason using Redshift it takes forever to get an image in the RenderView when the particles are activated – even though cached. It takes about 5 minutes for the image to appear. How comes that happens even if I cached everything before. It even crashes Houdini. Might I be doing something wrong ?
I’m exporting the particles as alembic now to see if it helps, and exporting as alembic also takes forever 🙂
Thanks a lot !
Hey Yann, it may seem counterintuitive but you don’t have to render the particles as Particles in the OBJ tag. Just tick the “Instance SOP Level Packed Primitives” in the Instancing sub-tab in the Settings Tag
In your shared scene you render out with Solaris and activate some sort of “instance” for the POP. I’m not using Solaris and I’m using Redshift. I guess the issue is that my particles are not instanced. What would be the workflow to instance the imported geo (without using Solaris) ?
Many thanks !
Hey Yann, I’m going to answer both your questions here, as I think they have the same culprit: As we’re creating a huge number of packed primitves (or instances, as a more general term) here, we have to make sure our rendering engine is handling those instances the right way, without accidentily creating a huge pile of data for itself to process.
I’m unfortunately a bit rusty with Redshift, so I’m just going to point you to ep 21 and 22 of our rendering course, where Mo goes into more details about instancing with Redshift: https://entagma.com/courses/rendering-101/rendering-101-pt-21-instancing-in-redshift-plus-a-bit-of-shading/
