I've been trying to tweak fall off, etc, to make it look less, how do you say,  transmappy-ish.

(I'm giving up on dynamic hair for long hair for now.  Long long hours for naught.)

Is just the nature of the beast, I suspect.
To me though that looks like it's simply a poor transmap, like it didn't use pure black, RGB 0,0,0.
Or it has too much spec in it.

So, I should check out the tr jpg.   Thanks!  

That is the Mark hair btw.

I had to use my handy dandy franken morph to squeeze James's head under it.

How did you export this image from Poser? More specifically, where did the white background come from?

I suspect that you did not render over black, so the Poser background colour bleeds through into the semi-transparent pixels in the hair, giving the grey pixels that you see there. You can fix it like this:

Use the render setting "Render over: Black". Export the render as a PNG image, which maintains transparency. Then you can put your image onto whatever background you want and you won't have the grey mixed in with the semi-transparent pixels.

I orig export my renders to a png file and when I saved it to jpg to post it here, background automatically turned white.

Let's see if renderosity will let me attach the png file

here's the same hair from the back.  for comparison, that's M4 in the Chevalier and David in Kurt hair.

and i see i have render issue with David's knee.  another job for the blur tool.

it must be psychological, but i just noticed when I mix Daz and Poser characters in a scene, i tend to make them a little oppositional.

oops, I'll have to resample it down.

If the "background automatically turned white", the original render PNG must have had a transparent background. So go back to my suggestion for fixing the problem. Did you try it?

not yet.  I'm searching to see if anyone has put out add-on mats for the mark hair.

I tried putting my own hair on the flatbed scanner.   that method isn't working out too well.

Okay, maybe I misunderstood the problem. I thought you wanted the hair to look less wispy and semi-transparent. That's just what render over black will do for it. :O)

Kewl, IsaoShi, I'm glad I read this thread - never noticed that option before, or at least, if I did, I had no clue what it was for. :)

Yeah! I was having that problem too and have totally fixed it. Actually, it was worse with big patches of white and gray. Sooo I also noticed "smooth polygons" was checked and so I did that too. What other boxes on that neat little menu would be good to check?


MistyLaraCarrara posted Fri, 21 August 2009 at 10:57 AM

I tried it with the black background.  Looked a little better.

It's not that its too wispy, I wanted it to look a little less not-realistic.  (if i may use a double negative here.)

There was a separate specular map of shaded gray.

I spent the rest of the night trying to fit Michael's Valiant/highlander to James.

Our poor James needs more options.

I really hate the texture maps with transmap hair, so i created a shader that removes that horrible pre-draw light effect from the hair and follows the hair. i will be adding this shader to the freebie section here at some point... oh and this only works on hair that has the transmap going from top to bottom....(will have to pick BB brains if someone wants left to right,lol)

the second pic shows the how when the light has moved the hair reacts to the new position as it should
