ID mask or RGB mask for Corona Hair

[hankusp]

Hi
When I render an object with C4D hair and Corona Hair material aplied I do not have hairs in my RGB mask (connected to either Material ID of Hair material or Object ID). I do not also have hairs in my ID maps. I just have "naked" object, without the hair object in my masks.
Is therea  way to make it working in masks?

Anybody could help me? There is no way to do that? How to mask hair object in Photoshop for postproduction then?

Is your mask comp tag on the hair object or the geo?

[hankusp]

I've tried both options. I add it to the whole herarchy too (Hair object + geometry together). Nothing works for me...

Hi there, can you please share your multipass settings?

[hankusp]

yes

[Beanzvision]

Thanks, and can you share an image from the VFB multipass?

[hankusp]

yes, sure. Thank you for your help.

Not sure I understand what exactly you are trying do...
Masking hairs like this? If so, maybe attached c4d file can help.

Hi
Jojorender - thank you for your help. It looks very strange, but the problem is in my Hair object. I don't know where. If I replace my Hair object by yours (the rest ofmy scene remains unchanged) masking works properly... Well - I don't know what can be wrong in my hair definition

Can you share your scene with us?

Also, if you changed versions (C4d or corona) during 'work-on-project', move (copy/paste) all your elements to a new scene file.
Oftentimes this helps.

Scene attached.
I did something wrong with hair definition. I don't know where... If I make new hair definition RGB masking works properly.
I'm total newbie to C4D Hair

It seems the problem was with the hair material. Not sure what exactly. I created a new one and copied the settings etc. Now it is working.
