Being of not entirely sound mind and finally having a few extra minutes (and brain cells, thanks to LaurieA - NOT GIVING IT BACK, LAURIE!!!) I've decided to take up a thread on getting more realistic renders (oh, yeah, did THAT ever devolve into something undefinable!) at this specific point where we had this cool shader set to experiment with, which people all refer to but I've yet to see anyone play with it at all.

Here we are, 4 year on, still lamenting the burnt-in specular plaguing our texture maps and I've decided: let's try this thing.

I wasn't sure which version of Poser this was initially attempted on. Seeing how it was BB, I'd say it was probably Poser Pro. Seeing how it was BB, I'd say lighting was dead-simple. GC at 2.2?

Right.

Oh, I am SO whacking at a hornet's nest, but oh well. Let the rubberneckers all gather 'round and watch me cop it. It's all good. :biggrin:

So: Poser Pro 2012. 1 light: inf, map size 1024 (for shadows?), 100%, white, positioned at 0, 0, 0, all shadows off... and IDL off, and Use Disp maps off and geez, virtually everything off except synch at 2, GC at 2.2, Pixel samples 10 (for now), min shading rate 1 (for now).

I'm using the high-res square to display my texture. Final Render setting will be at 4000 x 4000, now at 2000 x 2000. Set the camera focal length at 300 (minimize distortion? since 25 = wide angle|high distortion , 300 must = extreme closeup|low distortion? dunno).

Test render of my target texture (nose and lips):

Render time: @1 min
That's for a whole face. Might need to up Pixel Samples as well as min shading rate?

Anyway, let's put that spec-remove node set in place:

After this render:

...I thought I would try it with render GC at 1. Orangey image. I took value_2 of the subtract to 2.8 and got:

sooo a lot of the spec has disappeared and on the lips, it's a colour.

Stopping now just because there are so many things I'm unclear about, like what about GC, for instance.
