Having trouble with new dforce hair.

I hope im just doing something wrong. Im following the quick start instructions as I understand them. When I render, my memory shoots through the roof and daz crashes.
Maybe my memory is too low?
Anyone else having this issue?

Yes, it is the most bizarre hair, I have ever purchased.
dForce simulation works well, but any preset, I have tried, gives me that:
How do I get actual preset colors to appear on the render?
i have but not yet tried; I'll get back to you.
Thats strange. I have been able to apply color, I just cant render without crashing daz. Ive also had no issues with simulation itself. You cant apply any of the color presets at all?
Thanks nicstt.
It looks like, so, but have not played with it any further.
If Linday would drop the explanation, that will be great.
Not having any issues, other than it's holding its shape too well, but not played with settings yet. I have plenty of RAM, and it hasn't use above 24GB of RAM in total so far
Are you following the quickstart instructions?
Yes, I have following instructions, but hair does not render correctly (only showing colored material zones):
1. Load dForce Side Bob Hair
Hair is loaded with layer color display as default. It’s useful for adjusting
movements and visible simulation result.
2. Apply Global Simulation Preset. This Preset adjusts type of collision to Best, Start
Bones from Memorized Pose to off, and Gravity to 5. Gravity is very important for
simulation results. Dynamic Hair Settings are set to use high number of Gravity.
3. Pose character, avoid collision with body or cloth and use Movement Morphs if
needed.
4. Run simulation and stop it when the haircut looks as expected.
5. Apply Color Preset.
6. For better light adjusting use PR Hair Viewport On Preset to see hair in preview
render.
7. If hair looks good enough for final rendering, use preset PR Hair Viewport Off,
‘cause when PR Hair Viewport is on, it is consuming a lot of RAM.
8. Render
Even worse, when I try to apply any other hair shader material, I have,
it also does not work.
Useless hair for me at the moment.
I was just able to render by lowering the line teselation from 5 to 1. Still seems to be using alot of memory and I havent noticed any difference between PR Hair Viewport ON/OFF.
Ok, figured some things out. I think this hair might be too much for my memory (excuse to upgrade ram).
@Artini , I think you might be applying the material to the wrong part (what you see in your render are the sim mat colors). The materials need to be applied to the "dForce Side Bob hair base" which in under the "dForce Side Bob hair Genesis 8 Female" in the list. Works fine otherwise over here. No memory problems, but it does use ~3.5Gb on my RTX2080ti (that includes a naked V8).
Ciao

Nope, I prefer to mess around, but will try and get back to you
Edit:
Didn't use more than 14GB of RAM during the simulation; rendered on 980ti with 4100MB used about 18GB os system.
Seriously...upgrading your hardware to be able to render a single hair model...18GB RAM? Wow, I'm definitely playing in the minor league here
Just tested, no change.
I am using Daz Studio 4.12 Beta.
Could that be a problem?
I know right? Ive been reverting back to G3 just because its easier for me to fit more on screen. Oh well. I knew that the day was going to come when eventually my gear wasnt going to be able to hack it. My computer still has alot of life left in it. I think im just going to have to be even more selective about what I buy from here on out.
Ill post my relevent pc info here the next time I get a chance. Maybe if you can see my specs it will make more sense as to why im having issues with the hair. Memory and such still seems like alot of hocus pocus to me.
Just tested this hair with 4.12.0.83 Beta. This is resulting render below. Was just a quick out of the box with (1) hair color updated from multi-color preset and (2) stiffness changed for this pose.
When you apply the hair colors, you need to be in Surfaces tab with dForce Side Bob Hair base selected in that tab, then click color of your choice. Many mats only get updated that way, as opposed to from the scene tab.
Unlikely. I have multiple apps open, but not used more than the 14 in total.
The render I just posted is part of a larger scene with many things not visible in render zoomed in window.
My WinTaskManager showed just under 31GB Ram usage @98% total PC system ram used. dForce hair certainly contributes quite a bit, but I didn't do actual number studies yet. After render DAZ system-mem usage dropped back to 10GB for a medium complex scene. Which is standard from what I have seen. Also, remember someone posting that WinTaskManager may not be the most reliable tool. But have noticed that when I see bottlenecks WinTaskManager is usually reporting correctly.
Seems it is time to upgrade to 64GB. Scene optimizing all the time down to 2k from 4k is just another time burner.
No change for me in Daz Studio 4.12.
None of the color presets works for me.
Expand the hair figure in the Scene pane - that is a skullcap and the hair is attached to that, that child item is what needs to be selected for the materials to work.
Thanks. Finally get it to work.
Agreed. Seems more and more addons just keep pushing the boundaries up and up. I refuse to upgrade DDR for one of two addons that are part of a larger scene.
i am glad this thread popped up. I love Lindays older, non strand based dynamic hair, but this one just seems too demanding.
Just did a quick test to help myself understand what system memory demands are being put on my system by this dF hair.
Test was 1 G8F, one outfit, dF Side-Bob Hair and nothing else. To compare, also tested April's dF Faye Hair with out of box settings.
On load of this saved file, WinTaskManager showed about 2.5GB usage.
At peak usgae before render the WinTaskManager showed over 13GB.
After render, mem used is 9.2 GB.
Very important. Close the existing render window by saving or whatevs, and it goes back down to 3.6GB.
Repeated renders of identical scene with closing render window each time brought always back down to 3.6GB
April`s dF Faye hair gave a very similar result.
Initial impression is would seem anyone with 16GB could render dF hair with a simpler scene, including this one without mem-issues. Though scene optizimg to 2k would be a good idea if you do add any amount of other items to scene.
Just ordered 64GB to replace my 4x8GB.
Larger scenes with many parts can be demanding.
Memory was suprisingly cheap for higher quality compared to even 10 months ago.
This needs a system requirement warning in its product page.
Don't think it's just this hair. Would seem that any new dForce hair (SBH based) is pushing up demands. Just tested PhilW's Femme Fatal Hair under same conitions as listed above, and at peak render was almost 12GB. Again is WinTaskManager a fair tool to measure this? In case you missed it, in previous post April's lovely dF Faye Hair also performed similar to Lindays Side-Bob-Hair.
To be fair, here is result without dF hair (each time, hair was substituted, scene saved, DS exited and new sesion with save loaded).
OOT's newer Mega Updo with Base, Bangs & Bun loaded reached a peak mem of 8.5GB.
Using an older G3F hair Bardot Hair reaches just shy of 7GB at peak just before render is complete.
For years, I have thought that daz needed to post system requirements for these products.
Its a really nice set of hair but my patience for it has run dry. Going to return it. Will reconsider whenever I get around to upgrading. Thanks for all the comments everyone.
