this is regardless of texture filtering on or off.  I'm not rendering with gamma on, just with HSV tone 2.2

regardless of quality, and anyway shouldn't the preview be the lowest quality.

Did you remember to change the gamma on the transparency map to 1.0? oh wait you said you are not using gamma. I don't know then.

it's the daz  mitsu hair, but I have had this same problem with other hair, and it is not the gamma. When I do use gamma I use a script to change all those transmaps to 1.

Has no one else seen this effect?

It's not just hair that takes a loss of resolution. Try lowering shading rate. If that is an old hair figure then you can displace it a small bit from texture (,001 inches). If not you can up your pixel samples. This is old school trickery, though.

I don't get what you mean by displacing. I can try those other things.  But the thing that strikes me as odd, is your suggestions are increased quality settings that take longer to render.  The hair looks best in the really low qual preview image - does that not seem odd to anyone else?

oh, and on another note, I just noticed V4 eyelashes stick up when she's asleep - not very natural looking.

That looks like texture filtering. It needs to be turned off for all trans maps.

Now that could be it, although I used the SVDL script to turn it off for the whole scene, maybe it doesn't turn it off for the transmaps.  You could be onto something great here.

Anyone got a script to turn it off for the transmaps?

Love esther

I'm rendering right now.  I'll turn it off after, and let you all know how it worked out.

If you're wondering why I"m not rendering to queue, it's because I like the face camera angle I just got, and couldn't reproduce it on main camera.

Love esther

lowering shading rate to 0.2 and setting pixel samples at 5 did nothing for the hair.

And I checked the transmap texture filtering and found it is set to none (and I was so hoping for an easy fix.  I really thought this was going to be the answer)

Love esther

well you put an idea in my head.  Just now I tried turning texture filtering onto highest setting for the transmap, and you will never guess what - the problem has resolved!

well there had to be a reason why such a thing as texture filtering was in poser, apart from being annoying and making seams appear left right and centre on the textures.

Love esther

Don't set texture filtering to none for hair. At least, that's been my experience. Turning off for everything else is good, just not for hair ;o). Also, setting it to not visible in raytracing can make it look like crap too. Of course, all the above makes the render take longer, but if you want the hair to look nice, we must sacrifice...lol.

Laurie

Sacrifice? where's me robe.. who's got the goat!?! why did'nt we get the memo.. Ai Ai Cthulhu!

In the second post, had you not said "this is regardless of texture filtering on or off" I would have suggested turning on texture filtering, since this is what it's for.

Well, one more thing to remember, but this is definitely worth a try. Thanks for bringing this up.

Oh no I didn't turn texture filtering on for the hair.  The problem was fixed by turning it ON QUALITY FOR THE TRANSMAP OF THE HAIR (not the hair texture). It fixed the problem without needing fancy settings.  Fancy settings did not help the problem one bit ie no sacrifice required.

What? scratches head

Yes, I don't know but I tell you it worked. I don't even know what made me try it.

Love esther

I suppose it had to be some sort of thing akin to preview mode, as the hair looked better in preview.

This has been a very confusing thread.

Esterau started by telling us

Quote - note the hair strands go dotty.
this is regardless of texture filtering on or off

The correct solution was to turn it on, but the initial claim was that having done so already it made no difference. Later we learn that this claim could not have been accurate, but some of us did not mention texture filtering because estherau established it from the start as not a factor, even though it is THE factor.

Then, having established that turning it on or off did not change anything, gmadone gave us the advice

Quote - That looks like texture filtering. It needs to be turned off for all trans maps.

This advice is incorrect and ignored the initial claim. I would have said that TF needs to be on, except I read that estherau already tried that and said it didn't make a difference. But remember, that was not true. Then, contradicting both of the advice and the claim that TF makes no difference, estherau said

Quote - well you put an idea in my head.  Just now I tried turning texture filtering onto highest setting for the transmap, and you will never guess what - the problem has resolved!

I don't know why I would never guess that, because it is what I would have guessed, but for the fact that the second post said TF makes no difference. Had I ignored the second post, I or Laurie would have said TF=ON would fix it, and nobody would have been confused.

Estherau, you seem to be unaware that you told us from the start that TF had nothing to do with it. All the stuff that came later is very confusing to people following this discussion.

There are so few pixels in transmapped hair that it needs to be antialiased. The way to do that in Poser is to enable texture filtering. While it may be true that some things don't need it, like some fabric textures and what not, hair definitely does, and that includes brows and eyelashes ;o). Transmapped hair however, does take a very long time, especially if you have IDL enabled and/or the hair model has lots of layers.

Laurie

So many, not so few. The problem is that when the hair is presented in a render resulting in one render pixel = many hair pixels, you have the need for the Multum In Parvo, Latin for much in a small space. Multum In Parvo is abbreviated "MIP" and thus we have the CG term MIP Mapping. Poser texture filtering is MIP mapping. Enabling texture filtering enables a special technique for dealing with Multum In Parvo - i.e. lots of hair texture pixels need to be crammed into a few render pixels.

If you do not enable it, then the renderer just samples the texture at one point for each rendered pixel and you get artifacts.

Cool.... I did not know that.

well when I said texture filtering didn't make any difference on or off I wasn't thinking of just transmaps, I was thinking of the main texture.  I never thought until later to just turn it on for the transmap.

Try checking "Reverse Normals" in the material room.

pssst it's solved ;)

well, its too late for popcorn. I will surely remember the fix, however.

have you had the same problem?

if you're talking to me..yes.
but recently i have moved to IDL lighting and have quit using hair so I can get a render out in less than 20 hours.

"and have quit using hair "

yes who nees hair?  characters look fine bald.

Well you could always render to queue and go to bed if you have poser pro 2010

IDL does take a long time.

Love esther

When I turn off texture filtering for all but the trans map, sections of the hair disappear, and in general it looks thin - i.e the skull can be seen through sections of the hair.

Noticed it on WASG hair in PPro 2010.

But are you setting the Gc for the transmap to 1?

With IDL dynamic hair renders far faster than transmapped hair.
