bif_particles to create_instances issue

[xianwu_liu]

Hi, I am try to use Aero bif cache to create instance with different object.
So I use read_bif_particles and create_instances nodes in bifrost graph to make it.

But for some reason the particle id didn't been read or someting, instance randomize_scale and rotation keep changing in every frame.
only

Any idea about this?

Can you post a scene, maybe just like 5 frames or so? 
Anyhow if you have an ID that is consistent make sure you connected in the `instance ID override`

Thanks for reply, here is the playblast

This does not help me to help you though I see that you pts are jumping. Did you try what I said above? If that does not work, post a scene not a playblast.

Sorry about that, I misunderstood.

Here is the attached file.
By the way, I couldn't find the instance ID override attribute to connect, so I didn't try it.

Thanks for the help.

So as I mentioned, you need to get the point id from the pts and connect that to the instance id override. Here is a fixed file for you.

Wow it's working, thanks a lot!  However, there's another issue.

My rendering engine doesn't support rendering Bifrost graphs directly, so I need to export them somehow to Maya particles or MASH.

I've tried these two solutions, but it seems I can only get the position information and nothing else

(size, id, rotation etc).

Here is my files and plugin in attached, could you let me know any idea about this?

What render engine are you using?

[xianwu_liu]

I am using Octane to render.

I can look it up later, but the heydoubleu plugin should work it should transfer, point_size, rotation, etc just make sure you are following correctly what he is saying. 

[xianwu_liu]

Thanks, I will check again as well.

[xianwu_liu]

BTW I just notice the point scale and rotation still jumping every frame.

Could you please let me know how to fix it?

Then just set the point_id on the pts so the seed does not change. Like this - without the override. 

Make sure to type the property correctly
