Daz Very strange problem with hair

[djahdjah]

Hi,

Sorry for my bad english, it's not my native langage.

I'm just starting out with daz and I'm having a very strange problem with the way the hair looks.
I created a small animation that I encoded in webM and the hair is more “detailed” during the animation even though the same images were used:




First image is picture of my animation. The second is the same image, but used after the animation as a transition to the next image in rpg maker MV.

Basically, when I look at my renders, they're like my 2nd picture, but when I encode my video, the video is like picture 1. And if I use them as a simple series of images, they're like my 2nd image, it's crazy...

if anyone has any ideas, I'd love to hear them.

thanks in advance

edit: I tried with 2 different hairs, always the same problem.

Hi,

I've figured out how to avoid this problem, even if it doesn't suit me.
I have to render my animation in jpg instead of png.

I would suggest that is related to how the video encoder handles alpha transparency channel. JPG does not have an alpha channel, but PNG does.

A "correct" display renderer will take that into account when displaying (or processing for video?) the image, but if it does not, then the fine hairs at the edges of that hair asset might be rendered as "fully visible" instead of "mostly transparent". I think that would explain what you are seeing. What software are you using to assemble the image frames into a video? "ffmpeg" is surely the best one, and I assume it would support png alpha transparency correctly.

Hello,

Thank you for your answer, it helps me a lot.
It seemed to me that it was coming from the video encoding but I didn't know how to solve the problem.

Now that I know where it's coming from, I'll see if I can fix it.

I use shotcut for videos, I've just looked at FFmpeg but it looks very complicated and I've already got a lot to learn with daz.
But it'll probably come in handy later when I start mastering daz.

In any case, thank you very much for your reply.

Edit: problem solved, I hadn't chosen the right video codec, thanks again.

Oops wrong manipulation, sorry.
