Poserfusion Cinema4D converting materials issues

[Matt]

Hey guys,


I've been experimenting with various demo plugins, and I've had some issues converting materials to Octane materials, so I was hoping others can share their experiences.

For example, the Poser Octane demo plugin can convert the materials to Octane materials perfectly, but the problem I encounter is when I import the same poser model into another 3D application, and then convert the same materials to Octane materials.

In Cinema4d I imported the Poser scene file using the plugin Poserfusion, and then I converted the materials to Octane materials using the Octane demo plugin, and the converted materials were too bumpy, the eyelashes were too thick and black, and the eye surface was pure white. I could then go into the material settings and start to fix them manually, but this takes a long time.

Is it possible to convert materials into Octane materials, inside Cinema4d, as accurately as the Octane Poser plugin can?


Cheers,

Matt

The Poser plugin definitely does not convert materials perfectly. It just attempts a reasonable "approximation" of Poser materials using Octane materials. In order to get materials (especially skin) to look correct, you still need to do a lot of tweaking. For example, there's no straightforward way to convert Poser SSS to Octane scattering.

In your case you're dealing with Poser -> C4D and then C4D -> Octane, so there are multiple ways for results to get weird. For example, is the EyeSurface material showing up with proper transparency in C4D materials? If so, then maybe the C4D -> Octane conversion isn't interpreting the transparency correctly. If not, then that's a problem with Poser -> C4D. Same thing for bump map height and other textures.

Hey dsyee,


Thanks for the reply.

In hindsight, perfectly, was the wrong word to use, but in comparison to the results that I was getting when converting textures to Octane textures in Cinema4d, the results were very pleasing - there were no obvious inaccuracies converting the textures in Poser, even if they need to be tweaked for aesthetic reasons.

C4D to Octane conversion is the problem, as the C4D materials are absolutely fine (transparency included) before I convert the textures to Octane textures.

I've come to the conclusion that Cinema4d Octane plugin cannot convert the materials accurately straight off the bat, and no matter what, you will need to tweak them manually.

Yes, the Poser conversion works shockingly well, considering how different the material systems are. But then again, Paul is brilliant.

I haven't had much luck with the Maya conversions, either. You could always ask the developer (aoktar) to tweak the conversion a bit, though.
