Hi we are rendering using C4D 2024.5.1 and Octane 2025.2.0 and getting inconsistent cryptomatte colours depending on what node is rendering those frames.

We are using cryptomatte in 'material node name' mode which I checked should deliver consistent results, exporting 16bit EXRs using DWAA ...

Ok, solutions seems to be 2 fold – you have to use vertex displacement, and because of this your cap geo has to be subdivided, not ngons. I chose Delaunay.

Unfortunately in my case this takes octane LV literally 5-8 minutes to calculate before showing in the LV. But once its loaded you can do ...

Are you using vertex displacement or texture displacement? VD is crashing my scene because of the number of vertices I have so I've been using TD.

Thanks for getting back to me.
Geo is made by extruding a spline. I have collapsed 'C' the extrude parametric and selected all vertices, selected all and optimised. Didn't make a difference. Perhaps Im misinterpreting something? I presume by merge vertices you mean optimise??
I also tried taking one ...

]Hi, I can't figure out if there is a way of stopping the displacement from disconnecting the caps and extruded edge.
I have used a material selection to just choose the object cap and applied a displacement material to this, and another material identical, except with no displacement to the ...

Thanks Juan.
Can confirm I just had this issue in Cinema 4D and turning off the denoiser and 'resend all scene data' fixed it.

Thank you for getting back to me Beppe.

I followed your steps and I am still getting a crash. But it did so at the moment the path tracing had finished and the denoiser wanted to start.

I am trying to limit what I use in the background but need chrome open for work purposes. Spotify is open as ...

Hello, I am rendering 1000 scatter objects that are glassy cubes containing rooms and getting the following crash:

The xpKill modifier was the problem. It must reassign the particle id when a particle is killed which is a bit crap. Seems like an XP problem rather than octane though?

Please see the attached screenshots of the seeds and nuts – the geometry assigned to a particular particle randomly changes. This is happening on a local machine render with 1 3080 Ti.
