Sphere Particles from Standalone to Maya

[p3taoctane]

I need to export some sphere particles from an emitter in Maya as an ABC file into the standalone.
I can change their radius in maya ... they look grea... t but when I export the abc the standalone sees them as huge.

Any ideas?

Thanks

In Standalone or in an ORBX proxy node, you can change the spheres primitive radius in the import alembic settings, this doesn't update immediately you may have to save the scene and reload to see the change.

Many thanks that did it.

The only drawback in that is you would not be able to import two abc files with different radius particles because upon loading would it not read the default setting.

The only way around it that I can think of would be to instance geometry to the emitter.

Any other ideas?

Thanks

you can have different setting for different alembic node,
don't change the particle default sphere radius in preferences but in the setting of each alembic node :

Thanks mate this is a huge help

Out of curiosity p3taoctane - how are you exporting sphere particles to ABC ?

When we use instancer it's not recognised by ABC export, so our only option seems to be the sigilarium or MASH instancer>Mesh thing which is problematic in itself.
I'm obviously doing something wrong here (cone hat in the corner time for me..)

how are you exporting sphere particles to ABC ?

you just need to select particles node and export with Maya builtin alembic cache:

Oh that's interesting. thank you for the reply Calus

I'm pretty new to Octane as we're just assessing the viability of switching from 6 Years of VRay. So far it's a no-brainer. Particles have been the only issue so far.
I couldn't get either Particles or Instancer to render in Octane - only meshed particles.

Well Octane sphere primitives are still not supported by the plugin (to render particles), but you can workaround that by exporting particles as Maya alembic cache and import the abc in an ORBX proxy node.

About instancer what is your issue ? particle instancer and Mash instancer are well supported in the plugin ....

[ricoholmes]

Again, superb advice.. Thank you ! The NParticle>Alembic<OrbX is an interesting workaround

About instancer what is your issue ? particle instancer and Mash instancer are well supported in the plugin ....

Not, it seems, in 3.08.1 - 12.46-RC2 I'm afraid. They seem very fickle. I got them to render ONCE (after a number of scenes and attempts), and then as soon as I replaced the original
mesh to re-instance it never rendered instancers again. No matter how simple the scene I tried.
