Well I hope it will be fixed, after all the C4D Hair material, as it comes, it already works well with Octane (it's being rendered and correctly performs all the effects); it's only the use of a density map that "confuses" the hair material color production. Once that's fixed, there is no need to use this workaround and one can use the hair material directly. So IMO it's a bug.RahiSan wrote:Thank you Papillion!
That is a nice workaround!
The only Problem I see is that the Hair is still there, it's just invisible.
If you use your method to hide the hair in your provided scene it says 60k hair, same as without the opacity map.
With the "Density" parameter enabled in the C4d hair material though, it only says 25 k hair. But this, again, messes up the color.
This might have some performance or memory impact on larger scenes.
Maybe this can be fixed in future releases?

I'm still not sure what are you meaning exactly? It's simple, use hair material for any kind of geometric deformations. And use octane material for material effects.papillon wrote: Well I hope it will be fixed, after all the C4D Hair material, as it comes, it already works well with Octane (it's being rendered and correctly performs all the effects); it's only the use of a density map that "confuses" the hair material color production.

Please take a look at the c4d project that I posted. Is it the correct way to deal with hair materials?
Yes, couldn't understand on first try. After playing a lot, i have notified what you mean. That's a really bug on my side. A shift was happening on uv indices of hairs when you use density or scale maps. I fixed hopefully. Can you try this? That's reason why i'm asking more clear reports and some sample scenes to show the issues. People thinks that everyone could understand immediately. But it's not easy while working on something else and hard. Unnecessarily time loss until i got it. Btw thanks for this report. Best regards.papillon wrote:Please take a look at the c4d project that I posted. Is it the correct way to deal with hair materials?

Ok, glad you could see the issue. I'll be more clear and make more images and examples of the issues next times.
But I can't test it because I'm on OSX, are you able to make a test file for it? Thanks.

Nice to hear.RahiSan wrote:I tried the new release and it's working for me now!
Thank you for fixing it!

Fixed for me too, on the OSX version!
