Hi Ahmet,

For several builds in a row I struggle with rendering geometry when using XP Emitter and Octane object, and now I can finally replicate the issue.
The geometry doens't render when more than one XP Group is used. I.e. when the group number is larger than 1, geometry dissapears from render.
The scene is available here: https://disk.yandex.ru/d/va4wxAwzN4An8A

C4D - R26.107
Octane - 2021.1.6-(R2)

Hi,
you need add geometry to the Octane Particles tab, here is a possible solution: here is the modified scene file: ciao,

But this is even more bizzare! It turns out that the order of the geometry objetcs in the object tag corresponds to the group number - and it is just wrong. Currently it is impossible to make a random assortment of objetcs in one emitter within a single group. Previously it was possible. Right now it is just wrong. Even the manual says that "you can add as many objects as needed" and it should work. I wouldn't have noticed this issue had my scenes were not broken upon upgrating to the next version of the plugin.

This is the behaviour I expect. The setup is made in S22.123, Octane plugin ver 2021.1-(R2)

Do you mean something like this? In this case you need three groups, emitter 1 works only with group 1 and 2, while emitter 2 works with all three groups.

but it doesn't solve the issue at all. The point is that I need there to be only two groups - one for every emitter. And I want several types of particle geometry.
The setup you provided doesn't match the one I made in S22 - this is obviously a serious bug

{UPDATE]
As of ver. 2021.1.6-(R2) - the geometry index equals the index of the group - is the only possible way for this feature to work.

As we talk, you need to keep order and full objects in object list for both emitters as you see in the picture. Just putting it for referencing to next post for same topic.

Hi, as XParticles in their new version is out right now, may I ask, if you are working on this problem? Having more emitters and groups this problem is getting bigger and bigger. THX !

What avoids to use it like I said? Can't get what you mean with your question.
