Drop in OpenGL Interactivity with Octane [using demo plugin]

Thanks, and instance deformations?

and instance deformations?

The plugin use the Octane Scatter node for instances of a Modo Mesh, so all instances will be the same geometry so deformations of specific instances are not supported. You will need to have deformed meshes as separate Meshes, rather than instances of a mesh in order for them to be rendered correctly in Octane. See 13) at https://docs.otoy.com/Modo/?page_id=185.

Thanks I've gone through that seciton of the manual, but what I meant was if I make an instance of an objects and only want to change the position, scale, rotation of the instance this is only possible if Modos Render Cache is off.

[/quote]Displacements should work with the Modo Render Cache. Use the Octane Kernel->Settings->Polygon Displacement property to control the effect (mouse-over the property for additional info)[/quote]

With Modo Render Cache selected everything is extremely slow there is a long lag time with each octane refresh when using displacements. If I disable modo render cache displacements work fine, as does instance positioning, rotation and scaling, but there's the opengl performance hit. Same with instance positioning, scaling, rotations, they don't work when the modo render cache is active.

I understand the Modo Render Cache hasn't been fully implemented yet and who knows when this might happen. But your suggestion of the option to refresh the octane render only after mouse release would solve both these issues in the interim. Is the next plugin release far away? Not wanting to pressure you but this would make life a lot easier so even a rough indication would be greatly appreciated.

Cheers,

Yes, I would not recommend a micro-displaced mesh have Live geometry update enabled - that would not be viable. You should turn OFF Live Geometry Update for those meshes. You can also adjust the Modo micro-displacement settings to minimise the number of polygons generated, which will speed up load times.

So every time I simply want to move an object with displacements I need to activate live geometry update for that object and reload the scene to octane, then disable LGU again when I'm done? For large scenes this is workflow killer and NOT viable at all.

In any case displacements works PERFECLTLY for me only thing is having MODO RENDER CACHE selected KILLS IT. I don't know how I can possibly be more clear on this. Your suggestion for smooth openGL performance was to enable the modo render cache, but it doesn't support instances or play nice with displacements.

Really I use instances much more often, mostly for trees, shrubs etc. and this is my main concern. So..... what i would like to know is roughly how long will I be working with a stunted opengl performance until the next release.

I'm just suggesting that if you are using the Modo Render Cache, and have Modo Mesh items with displacement maps, make them NOT Live (and refresh the Viewport when needed).

In any case displacements works PERFECLTLY for me only thing is having MODO RENDER CACHE selected KILLS IT.

In that case, untick the Kernel->Settings->Micro Displacement properties, and use the usual Octane displacement map workflow.

I should be able to push tht change out with the first Octane 3 version of the plugin (within the week?).

Wow I was unaware version 3 was just around the corner. Does that mean I'll need to upgrade first before the fix? (just bought version 2 a few days ago)

You don't need o update until Octane 3 comes out of beta.

Will the first Octane 3 version of the plugin work with version 2 standalone? Sorry that's a bit confusing one would assume version 3 of the plugin would need to be used with version 3 standalone.
