Hi All,

This seems to be relatively new, though, it could be that the hair styles I'm trying are either new or I just haven't tried them in a while. Actually, the one I'm using right now is definitely not new. It has a lot of flat planes arranged about the head, but not all of them look like that (some look more like sculpted hair, rather than bent planes, if that makes any sense).

Anyway, when I render some hairstyles (made for v4), if they are far away (i.e. I'm shooting a whole body on the screen), I'm finding that they have white stripes along the edges of their textures. However, if I render a larger image, some of the stripes go away. If I render a headshot, I actually get no white stripes at all.

Is this an issue with old fashioned settings on hair shaders (I'm using PP2012 with IDL and, I assume, IBL). I've looked over the shaders and they look reasonable to me. Please note that this doesn't happen to all hairstyles, but it seems to be true for the ones I want for this character:)

I'm trying a super big render to see if the lines go away completely. When that is done, I can post pictures. I believe I have the most recent SR (3?) installed. I'm not suggesting that it started with 3, but...I'm not denying it either:P It seems like poser is trying to minimize memory by reducing textures for the smaller sections, and chopping off the transparencies a bit too early or something.

Any one else experience this?

try texture filtering none, or increasing raytrace bounces.

A screencap would be nice.

Maybe a gamma setting problem with the maps?

Check to see what the specular settings are...it could be that some of the edges are catching light. I would think tho that it's more likely that you need to set texture filtering to none or crisp.

I see this all the time with Goldtassel hair from Daz.

Turning gamma correction off fixes it for me, but that's not a solution I'm happy with. Alas, just altering the GC settings for transparencies does not fix the problem, nor does tweaking the specular settings. I actually have to go in, find the transparencies, load them in a graphics editor, and put them all on a black background (instead of white). I have no idea why.

I have no idea why people put the diffuse image maps that are used with trans maps on a white background either, It always leaves a fringe.

Example, from Yamato's tsuta for A3... Before on a white background, It was showing a fringe of white in render (not to mention the color was too garish).

After compositing the image over a sympathetic color scheme and some tweaking of hue and saturation the results were much better. No fringe and a much more natural looking result.

Above is an extract of the leaf plane from the Tsuta garment. No specular or bump, just the diffuse and trans image maps. The leaf on the left is the original texture with a quite visible fringe. On the left is the result after changing the backgound color to a comparable green.

ummm, meant on the right in that last sentence... don'tcha hate that?

Sorry for the lengthy delay, but I started watching one of the Lord of the Rings movies last night, and it took forever:)

So, here is what worked (kinda) and didn't:

Increasing Raytrace bounces: No effect

Setting Texture Filtering -> Crisp: No Effect

Setting Texture Filtering -> None: Helped, except one obvious place from my camera angle

Turning off Gamma Correction -> All back to normal, picture looks awful :)  Actually, the picture looks fine, but wrong. I like the colors with GC on.

This is DAZ hair, maybe from goldtassel...don't know (it's probably PC stuff). There is at least one non-daz hair that doesn't have this problem, but it is probably the same issue.

I think I'll take primorge's suggestion and paint the background similarly to the hair color. I think that will fix it along with turning texture filtering to None for the transparencies and see if that works. 

OK, render isn't finished, but the head is:) 

So, I used select to remove the white background from the texture, and duplicated the "texture part" 2 times moving the lower layers a little to the left and right. Then I painted the background a solid color sampled from the darker part of the hair texture and that does help it. I have actually done this before with plants' leaves, don't know why it didn't occur to me when it was hair.

That works too with texture-filtering set to crisp. For those who hate texture filtering, in this example, her hair was pixelated without it, at least where the strands fell across her face. I'll post a few of the renders to show the problem and fixed results. 

BTW, the hairstyle (after going to DAZ) was by Swam, Goldtassel and Zracheal (it was Chantal Hair). I was wrong about it being a PC item, so Moriador was right about the artist:) Interestingly, though, the transparency background was black on this one. It was the texture's background that was being picked up. 

here is a before/after, for those who might find this thread later (or are just curious). This was my original test render size (size of the pose window) and original settings that showed the problem the worst. I included the suggestions made here. Some did help, but didn't fully fix the problem without affecting the find render significantly.
