Octane render skin with odd texture

tuPadr3

Hello,

I'm really new to working with DAZ. and I'm learning using the octane plugin. I'm doing some test making a skin shader (just on the face of the model right now) and I notice some "odd texture" on some parts of the model, looks like a mesh. 

Can anyone help me figure out what can this be please?

I've attached an image to show the problem.

I hope this is the right forum to ask this kind of questions. 

Thanks in advance for your time
