Problem With Hair HELP..

Justin_Ames

Hi guys, 

I just bought those hair here : https://www.daz3d.com/dforce-pitt-bull-hair-for-genesis-3-8-and-81-males but they look nothing like the pormos... The ''Brown'' color looks gray. The 2 hair strands are definitely not as thick as on the pictures and the overall hair are also so thin we can literally see through them.... The character looks horrible... I played with every single morph options and nothing change that... I don't understand... Can someone help me make the hair look like they should? :(

Here an example of what it looks like:

Two questions: Is that a full render or just the Iray preview? Since that is dforce hair it usually won't show up fully unless you do a full render to save on resources. Second question: What tool do you have selected? Something like the geomety editor tool or mesh grabber will make dforce hair not render properly. best to have the universal tool selected.

It's an iray preview... You were right, the full render I tried after reading your message was just like it should've been. Thank you very much!

Better know the culprit of such an 'issue' , as it's one of the features of strand-based hair... Normally one is not able to 'correctly iray preview' a strand-based hair (SBH) in Viewport with default settings of it.

Select the SBH (sub-node of Hair Cap), switch on 'Preview PR Hairs' , then set 'Viewport Line Tessellation Sides'  > =  2. Don't set this value too hight because it will generate a great deal of SubD vertices / faces in Viewport, which is much RAM and VRAM consuming... As shown in the screenshot, level 3 generates nearly 10 Mils faces. That's why the default setting of a SBH is either with 'Viewport Line Tessellation Sides' < 2 or 'Preview PR Hairs' turned off.

So, just set it <= 'Render Line Tessellation Sides' but at least 2 if you wanna iray preview it in Viewport.

you can go to Render Line Tessellation Sides of 0 if you want to save on resources by making dforce SBH into curves.  But you need to change the shader.  Chevybabe25 has the line zero shader for strand based hair which has presets that can update Render Line Tesselation Sides and change the shader properties accordingly.

Yea, I saw that product but still have no chance to own it as I'm not short of resources FTTB. But since that product uses the very same Blended Dual Lobe shader (as described on product page)... and just with 10 texture maps, I believe we can tweak the settings on the current hair by ourselves... though tweakin a dual lobe will take some time. I roughly did it on this hair, the rendering result with line tesselation 0 is also good while balancing the resources and time...
