Octane for Unreal Engine 0.26
Changes:
  • Upgraded to Octane 2019.1.4
  • MorphTargets are now supported.
    *Skinned Meshes switch CPU skinning when using MorphTargets
  • New ORBX Importing: Unpacks an ORBX file and converts its content and scene to unreal assets
  • OctaneMaterials: Added functionality to set an unreal texture on RGB Image, Alpha Image, Grayscale Image nodes in the node editor
  • Added blueprint support for OctaneNode/Item. Octane rendertarget camera pin values can now by set via blueprints
  • Textures and mesh UV's are no longer Y flipped in Octane.
    *This should not cause any problems, but if textures or UVs behave differently in this version, please let us know

Fixes:
  • Fixed rotation UI issue on Transform Value nodes
  • Fixed UI issue where attributes would not show up when selecting Transform Value nodes
  • Fixed bug where custom output "clear coat normal" was not converted correctly to Octane material
  • Fixed various normals being incorrect on certain materials
  • Fixed various tooltips and UI

I hope it does. Let me know if it works with iClone.

Hello Chris

Great work you are doing with the plugin. I have a solution for realtime virtual sets for film, and for me is quite important the support of Octane Render in UE4.

I'm very satisfied with your approach, cause is very importat for me the ORBX implementation in my pipeline.

Questions:

1-When the ORBX imported, UE4 parent materials will be also created?
2-When the ORBX imported UE4 lights or emisive material will be also created?
3-When the ORBX imported UE4 environments will be created to match ORBX environments?
4-In the future, when ORBX imported, animations will be created in UE4?
5-Is Brigade (with realtime no noise render) going to be supported anytime soon, or is something that is going to take time? (suposedlly is going to be supported with 2019.2)

Best Regards, and thans for getting this done.

Do you mean if there will be a conversion step from Octane Materials to Unreal materials?

mrfactory wrote:2-When the ORBX imported UE4 lights or emisive material will be also created?

When we upgrade to 2019.2, unreal light primitives will be converted to unreal equivilants.

mrfactory wrote:3-When the ORBX imported UE4 environments will be created to match ORBX environments?

Ill see if it is possible to convert environment nodes to an unreal skysphere/atmospheric fog/directional lights.
Additionally, ill check if I can link the RenderTargetActor environment node with the converted environment texture

mrfactory wrote:4-In the future, when ORBX imported, animations will be created in UE4?

This is very difficult to implement, and will have very poor results. As Octane has a very different scene structure then Octane the conversion of animations would be very lossy.
If you need this you can import an ORBX as a proxy, this will retain the animation, but wont allow you to make changes in unreal.

mrfactory wrote:5-Is Brigade (with realtime no noise render) going to be supported anytime soon, or is something that is going to take time? (suposedlly is going to be supported with 2019.2)

Depends on what you mean by realtime. If you mean 30fps no noise rendering, then the answer is most likely no. We are working to get there, but it will take time.


What is it that you want to do?

Hello Chris, Thanks for your fast answer!!.

1-When the ORBX imported, UE4 parent materials will be also created?

Do you mean if there will be a conversion step from Octane Materials to Unreal materials?
Yes, the conversión from ORBX to UE4 materials is the most important for us.
----------------
The idea is to create a set with Maya, 3DS, C4D.... with Octane, then export to ORBX, then import to UE4 so that we can Previs in realtime, and then record the camera tracking data in FBX format with our system so that we can render the whole movie with Octane Render with 10x GPU HPC Servers.

We've been successfull doing just the modeling and the UV (UDIM) with external 3D app, and then, light, map all the textures and create all the materials within UE4, rendering both at the same time Octane Render and UE4 so that both have the same color and same light.
----------------
We are using this system for feature films and fiction series. This is one of our first tests, https://vimeo.com/263196460

Best Regards

This is very impressive. I am going to try some tests similar to what you have done. I'm trying to understand your workflow in more detail and exactly what is supported or not. However I think the best way is to try it for myself then ask questions. Thank you for posting this. It is very informative.

One statement I don't understand. Why is the advantage of rendering in both Unreal and OctaneRender simultaneously? Is it for the match-move of the the actor? Are you just trying to get to a preview mode of what the lighting, etc in the final render will look like because?

Hi Chris, it does work!....almost....
Morph Targets on the character transfer over.
It is interesting, if I drag along the iClone timeline, and UE4 moves respectively in realtime, the Octane viewport perpetually renders like a constant realtime update, it never completes itself as a render.
It constantly runs pixelated, but you can see the matching blendshape in the image.

But then it will suddenly look like it is going to complete a frame, and it crashes UE4.

I am using 4.22.3 because iClone doesn't support 4.23 yet.... :x

Octane updates the model everytime unreal claims the mesh has changed. Which means that if iClone sets the SkeletonMesh to "dirty" octane will start rebuilding the mesh every frame update.
Ill check if i can figure out why the crash is happening. I was hoping I didnt have to learn how to use iClone, but alas.

imported the orbx scene, and it was rotated by 90 degrees, and no materials assigned, and generic texture names, model had multi materials..

..is it ever going to have applied materials at all, since this seems to require making materials and assigning the textures all manually.. PITA, but still a bit better then nothing
