*Edit: Upgraded to Unreal 5.0 Release

Octane for Unreal Engine 0.10
Changes:
  • Upgraded to Unreal 5.0 Release (Has a known crash on shutdown)
  • Materials: Added support for custom material expressions (Custom HLSL). This can greatly improve certain material conversions
    *Main limitations for now are global variables and access to FMaterialParameter variables
  • Materials: Added support for vertexinterpolator
  • Lights: Spotlights now take SourceRadius into account
  • Octane: Upgraded to Octane2021.1.4
Fixes:
  • Materials: Fixed issue where materialinstance boolean parameters would not update correctly
  • Materials: Fixed issue where materialinstance would not properly reconvert when changed
  • Sequencer: Fixed issue where rectlights and spotlights would crash the ORBX exporter when using unreal sequencer
  • Materials: Fixed multiple minor material conversion issues that resulted in invalid octane materials
  • Landscape: Fixed crash that happened when a landcape has deleted segments
  • Landscape: Fixed conversion with segments starting from non-zero
  • Landscape: Fixed issue where textures would not load for material instances in landscapes
  • Landscape: Now correctly only updates after editing is finished
  • Brushes: Fixed crash that could occur when there are no brushes in the scene

Hi Chris, now that UE5 has finally been released 'officially', how long do you reckon it's gonna take until we can take Octane for a spin in it? Currently we're still 'stuck' with UE5 EA.

Looking forward to hearing from you.

Hi Chris,

First of all, thanks for releasing the UE 5.0 plugin so quickly. Really appreciate it :D

I'm using it inside UE 5.0 right now and I've got a question: I'm trying to create an Octane material, but when double-clicking on it to open up the editor, all I get is the window below:

It looks like the node editor is gone. Any idea what's not working here? Thanks for letting me know :)

Thanks for pointing this out. I replicated the issue by resetting the unreal layout, and working on a fix.

Thanks Chris. Does that mean that resetting the UE layout fixes this, or that you'll have to provide a fix, before I can get this to work? Thanks for letting me know.

I will need to make a new build with the fix.
Sorry, with that comment I ment that for some reason it appears that the bug does not happen when unreal editor stored the UI layout from a previous version of unreal (most likely 5.0 Early access).
So resetting the unreal layout made the bug happen on my machine.
