Adding things to my Your default startup settings/template?
Trying to make a default node tree for the AI Denoiser which will work for both Eevee and Cycles with out the need to swap connections and heres what i came up with. Any all and comments are welcome.
Did a little time testing for render speed and did not notice any different weather using the ‘Greater Than’ and Alpha nodes or not using them, tested with Blender 2.81
Using the Greater Than node as a “IF check” and piping the result to a Alpha node to display the correct input.
Hope fully the pics will explan better then my words 
Trying to keep it clean, this is the main group node (denoise node is inside)…
With-in the “IF-There” group is a Greater Than node and Alpha
Before plugging anything into the connections, all the IF-There groups must have nothing in there settings.
And the IF-There node group which will check for Cycles denoise data and if not found will use Eevee’s info.
Only tested this on some simple renders, but seams to be working pretty good.
Any opinions ?
