I guess I never noticed, but attempting to render a super basic particle simulation with particles moving from one group to another, the particles can only render through a single group channel. Maybe behind the scenes the channel input technically switches to another emitter idk? None the less, you can't put object tags with render particles directly on groups, so unless you want to use a bunch of generators or link to thinking particles and run xpresso for particle values which I don't want to do, this seems super odd that Octane cant simply track the particles from one group to another, its the exact same particle just taking on new particle values.

This makes it impossible to utilize XP to its best potential which is particle use. Cylces and RS both dont have this issue, is there a reason Octane can't read group changes while rendering attributes from both?

I can easily switch channels to get one or the other but not both simultaneous/when switching directly to a new group.

works fine on S22 with Octane 2020.1.5
But not at all for R26 and 2023 with Octane 2021.1.6 and 2022

Thanks!
This is a start, in the sense that the "groups - enable disable" would help, but currently in the stable version the only working method is multiple geometry designates to either group one or group two based on list arrangement. I saw some test builds in that thread, but is this to say that outside of 2020 that group rendering is disabled for XP currently unless you use one geo per instance?

Not sure what you mean exactly but there is a test R5 build to let users check it and fix me any problems. See it and give me feedbacks.
