Right
Firstly, sorry to keep asking silly questions!
Secondly - I have a SSS used as a mask for a river and also to place vegetation. I want to add a path using another SSS and again using that to mask the same vegetation anyone got any ideas how I can add/mix the two masks so that they can be inputed into the internal plant networks.
Hope that make sense

Should be possible to combine 2 or more SSS with an Add Colour node.
Cheers a great idea I'll give it a go.
Or use the merge shader for more possibilities, or just stick the one into the other's input (stack them).
Dune - The merge shader can cause some trouble (at least it could in 2.3) in
some situations as well as the stacking method,that is why I did not
mention these above.
Add colour works great
What kind of trouble did you encounter, Jan?
Using the merge shader in add mode resulted in varying intensities of the output.
Maybe I still have an example for that,I'll see if I can find it.
The stacking method didn't work at all in some cases,but I couldn't find out why
at the time.Didn't keep an example,because I wanted to get on with the stuff I was
doing.
I did notice that if you stack overlapping SSS's they don't really add up. I just used a conditional blue node to add two SSS's to make another sort of curve, where I changed the white to gray or white=2 and different sizes. All sorts of interesting combinations to be made.
Could not find the example so I reproduced it with one of my old files and set up
some more examples.Thought it might be better to put these in their own thread,
though.

Let's continue there,please.
Haven't tried the conditional for this kind of stuff yet.Maybe you can show that
over there too,if you like.
When you add masks, it's a good idea to clamp the result between 0 and 1 to stop any 'over application' of what you are using it to mask.

I can second that one ;) I mainly use scalar functions rather than colour functions since a mask only needs a single value to be calculated
