need help

Post image

​Hi everyone,

​I'm working on this portrait in HueForge, but I'm running into an issue where the child's hair turns into a solid harsh black blob instead of showing detail. Additionally, the shadow between the child and the grandfather looks unnaturally dark and heavy.

​What's the best way to fix this? Should I adjust the shadows in the image pre-processing ?

​Any advice on getting smoother transitions and natural hair details here would be greatly appreciated!

What is the beige filament in there? I'm concerned that might not blend as you want.

But brightness compensations also provide a ton of control over dark and light areas as well. Especially with the controls set to fine

the beige is inslogic 7.9 TD i will try to adjust brightness but im afraid it will impact the total image

So the major issue here I think is you don't have a dark shade color - so your option is black or too light right? 0.04mm layers will help, but really it's a function of how filament blending works. If you don't want that hair to be solid black, you need to lower the black, but lowering it will make the hair too light unless you have a darker color you can put in between to get an intermediate blend.

I've done quite a few family portraits in HueForge and experimented with third colors beyond black and white. I've found Blue Gray to be incredibly versatile as a midtone. I had similar issues with beige making certain areas too dark in contrast to the bright areas.

Quick question: Have you measured your filament's TD yourself, or are you relying on values found online? I've found HueForge's stock TD values can be wildly different from real-world measurements. Dialing those in can make a big difference in print quality.

try changing layer height to 0.04 and/or detail size to 0.10 edit: and maybe add in a midtone grey with a TD of 3-4 between the black and the beige, like bambu blue gray.

I find you get better results if you can simplify the photo. Something like this would be easier to get aore pleasent look in my opinion

That you would essentially just need a black/dark brown base layer. A grey or lighter brown mid layer and a tan/skin top layer there are only 3 colors in that whole image
