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 !
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/
