Unwanted Pixels in my render when I connect a deep map in the SSS Radius in Arnold 5 ( Maya 2018 )

Good Day,

I was currently doing my rendering in Maya and everything was ok until I reopened my project to render it. I see this tiny dot like pixels in my render ( see image below ) and I tried figuring the problem and it turns out its my deep map that I connected to my sss radius by a multiply node, but before that it was doing pretty fine I tried reloading the texture but no luck, the only thing that can erase those pixels is by deleting my deep map node and just filling it in with a red color.

Hope you guys can help me!

Cheers!

Hi @Lee Griggs it only appears on my SSS, and what I did on the multiply node is I put the diffuse in the input 1 and the deep scatter map in input 2 then connect that to the sss radius of my aistandardsurface shader. I get the NaNs when I input the deep scatter map in the input2 of my multiply node but if I just pick a reddish color for the input 2 the render is just fine. I double checked on my deep scatter map and saw no problem with it so now I'm completely lost.

What values are you using in the Multiply? What if you delete the Multiply or replace it with a Range, do you still get the NaNs?

Does it appear in all AOVs or just SSS?

@Max Tarpini Like a Deep scatter map a red map of your diffuse. When I try to connect it to my sss radius those little pixels appear I checked the deep scatter map and its all ok so I’m trying to figure out how to remove it on my render.

not sure what you mean by 'deep map'.
