Octane doesnt support attributes on instances yet. There is a workaround for that in Houdini. Check this thread https://render.otoy.com/forum/viewtopic.php?f=101&t=73105&p=372155&hilit=instances+cd#p372155

So, what is "Added support for packed geo instancing"? What is the reason to use packed ...

Octane has Dirt Node which does very similar to curvature node

Can't believe that 8 mb program can do such job. Tried on 150 mln voxels and still working. 30 mln particles in real time with forces and explosions. This is epic and has a chance to be a production standard. If you will make good integrations also in plugins - this will be game-changer. It's a lot ...

What I think now is maybe some python script which checks all nodes and if it finds simple constant and float nodes - remove it and place it's value directly to parent connected input. But I have no python skills, will try to find somebody for this work

When I import something from LiveDB, this produces a lot of nodes in houdini. For every option of material, it creates constant, float value nodes which is connected to Main material. So, it's almost impossible to do fast changes in such material. In the same time, when I use Octane in Cinema 4d, I ...

There is still no Translucency Input in Universal material. Do we need to use Transmission input and set Transmission type to Diffuse?

P.s. I need this for Megascan materials, they provide Translucency separate image layer but it's not connected to any port

I mean in Houdini. There is no Lambertian transmission mode in Houdini version of Universal material like mentioned in

Is it still not supported?

Latest 2020 octane has everything what you need. For me it's better now than Redshift. I am not sure why, but Redshift always gives me some caramel style. You can find this on all Redshift renders. But, Redshift is better integrated in Houdini

Found solution by myself

In case if someone is interesting, you need to add next python callback to button

hou.node('./octane_render_OUT').parm('execute').pressButton()
