Hi,
I'm looking for a renderer that fits into our pipeline and I'm testing Octane 4 right now.
We are working with Revit 2017 right now but will change to 2019 soon and I try to find some synergies with our real-time pipeline.
So far I really enjoy working with Octane, but have one problem and a few questions, someone hopefully can help with.
1. Problem - I frequently receive an error message when changing a node type, e.g. kernel from direct light to PMC. Once the error shows up I have to reload the Revit file.
The error starts showing up when the render view is opened, either manually or by the plugin after opening the viewport.
If I close the render view before I make any changes, I can prevent the error message.
When I tested the Octane 3 version, I didn't have this issue. I uninstalled the older plugin prior to installing v4 and removed old user files.
2. Grass
I have some trouble to wrap my head around how to create grass (particles) and use them in the Revit plug-in.
Creating a csv file in a DCC software with fitting plug-in, sounds a bit cumbersome. Especially because you need to export the terrain first to create the particle system.
3. Revit 2019 PBR materials
Revit 2019 introduced new PBR materials, though the Autodesk implementation is imho a bit strange and not clearly documented, I already asked them for some clarification on the Forum, but no feedback so far. If anyone knows the details, I would appreciate if it could be shared.
As I see it, they split up the "typical" PBR shader (in Octane the Universial material) into a couple of more basic shaders with some fixed values.
Are there any plans to update the auto conversion for this shaders, preferably to universal material?
4. Decals
Are there any plans to add the Revit decals?
5. Water
What is the usual way to render a body of water? Use a flat surface with a water-like transparent material and displacement for waves?
Cheers
Jan
