skin shader Could you help me with the skin shader ? :)

[rattle-snake]

Good evening here !

I'm brand new to Houdini but highly motivated to learn it

So far I'm doing some tests in order to render one of my characters (UDIM textures) with mantra using the provided skin shader.

Here is my SSS setup :

Here is the result :

I'm pretty happy with the result, but when I add a normal map (8 bits tiff), some black stuffs appears (really weird) :

What can I do to fix it ?

My second question is that if I disable the single samples parameter (in order to have a true multi samples SSS) :

Then my  werewolf is turning really brown :/

Playing with the Shallow/Medium/Deep density parameter I'm able to adjust nicely the power of the SSS.

But if I try to change the Shallow/Medium/Deep color parameter, the character remains always brown.

So... is there any tip in order to fix to restore the colors ?

Thank you in advance for any help

For the normal map issue, I found this thread :

http://forums.odforce.net/topic/19801-tangent-normal-maps/

However when digging in the skin shader I wasn't able to find some netbox subnets "normal convert" to replace with the fixed one.

It's really strange that in 2016 it's still a pain to load a simple normal map in Mantra T_T Or am I doing something wrong ?

Thanks
