Octane 2021.1.5b for Unreal Engine - 0.55 ORBX Proxy Tweet

[ChrisHekman]

Octane for Unreal Engine

Changes:

• ORBX Proxy changes:
  ORBX proxies have been changed to be more in line with how unreal materials and other uassets are edited and changed in unreal - and blueprint integration has been added via Node Params.
  
  
  
  • ORBX Proxy uassets now contain the ORBX data and no longer rely on an external orbx file via a filepath.
  • ORBX Proxy uassets now work similar to unreal materials. They can now be be edited and saved via their own unreal node graph UI.
  • ORBX Proxies now have Parameter Nodes (similar to unreal material params). These params can ben set in the ORBX proxy node graph UI, and they are retrieved via blueprint from the OctaneORBXComponent function "GetParameterNode"
  • OctaneORBXComponents are now properly instanced, and their Param nodes can be different for each component instance.
  • The ORBX Node Graph now has an apply button that applies changes to the ORBX components in the scene without saving the changes to the asset. Similar to unreal material editing.
• Textures: changes to UDIM size are now tracked and applied to octane
• Textures: changes to LOD bias are now tracked and the specified LOD bias is applied in octane now. This can save a lot of memory.

Fixes:

• Fixed crash that could happen in materials (encountered in metahumans hair materials)
• Fixed one of the exit crashes in that occur 5.0
• The post process volume that gets created for overlay rendering is now properly cleaned up when overlay rendering is turned off
• Fixed an issue where the value of attribute pins in blueprint functions for setting octane attributes would not be retained
• Preference window colors are now clearer
• Preference window colors are now clearer

Hello Chris

Thank you for creating great software, very nice. I've tried ORBX Import and it works from C4D, in order to work minor manual adjustments in UE4 must to be done. I would like that the import plugin ask if it is Static, Stationery or Movable. Also some textures in UE4 must be linear, (Roughness, Specular...) would like also to prompt if this texture are Color, or Linear Color, when importing. If we use emissive lights with OctaneRender, we don't have any problem with UE4/5, just only need to activate on each Object Details/Light: Use emissive as static light, i wonder if we can automatize the activation of this checkbox on all emissive that are lights.

With 3DStudio Max or Blender, seems everything is based on alembic cache, don't know if we can convert into something more compatible with UE4/5, the scene appears rotated and don't seem to work.

Is there a way to import ORBX from Blender or 3DsMax like we do with C4D, i mean preserving all objects and scene?

Best Regards

Oscar

Hello Chris

Also some textures in UE4 must be linear, (Roughness, Specular...) would like also to prompt if this texture are Color, or Linear Color, when importing.

Would it be possible to give me a small example ORBX that shows this issue when imported to unreal?
I take it the linear color problem only occurs in the unreal renderer, and not in the octane viewport?

If we use emissive lights with OctaneRender, we don't have any problem with UE4/5, just only need to activate on each Object Details/Light: Use emissive as static light, i wonder if we can automatize the activation of this checkbox on all emissive that are lights.

Ill see if i can add this.

I would like that the import plugin ask if it is Static, Stationery or Movable.

As this is a component setting in unreal, whouldnt this be easier to do in the generated level where you know which object you selected? Instead of getting a list of prompts?
Or do you want to set them all via a default setting for every component in the scene?

Is there a way to import ORBX from Blender or 3DsMax like we do with C4D, i mean preserving all objects and scene?

This is up to the Blender and 3DsMax plugins. They would need to support the static/obj export feature.

Octane has 2 methods of exporting to ORBX.
- OBJ
- Alembic/FBX

When exporting to Alembic/FBX all geometry gets condensed into one underlying Alembic/FBX asset.
C4D Plugin supports both methods I believe, so does the Unreal plugin.
I dont know if 3DsMax/Blender plugins support the OBJ export version, you will have to check with them.

Thanks so much Chris.

To create materials we usually use Poliigon Textures, those ones need that all Grayscale Textures (Roughness, Specular, ...) to be Gamma=1.0 or uncheck sRGB.

Find attached on this wetransfer all the ORBX, UE4 project, c4D projects, textures and HDR for testing https://we.tl/t-SeBkiTKfrl

I would say the best is to set defaults for all import settings.

We will continue testing the ORBX-UE4 workflow, it is very important for us.
