I can't seem to find anything in the Physics / PhysX Modify Panel in my Character Creator 3. Maybe this feature of compatible Hair Elements are only available in CC4? I've found the same feature though in iClone 7 so I can test this out there later on. Anyhow, I will send you privately a pic of the character that uses HairStudio Vol.1 elements with the Headshot image just to show you what I have and how I went overboard with using hair. :laugh: This is my first time using dynamic hair that I bought from the Content Store and my first iClone project so what I have is still pretty rough and not worth sharing publicly yet. :P 

You can activate/deactivate the Hair Softcloth/Physics of each hair element via the "Modify" Panel. I currently don't have access to iClone, but CC should have the same layout - so here is a quick screenshot. Just select the hair element, go to the "Modify" tab and select/deselect "Activate Physics". 


Also, feel free to share a pic of the hair design you wanted to create and I'll see if I can give some useful tips.

Got an additional 10+ FPS having done this! So I'm now reaching 30+ FPS! Awesome, thanks!!! :D

Hello there! By disabling Softcloth Simulation for each hair element in iClone I guess you mean removing the Vertex Animation for each like in the GIF animations below?





(Source of these GIFs can be found here.)

If I only knew initially how to further optimize hair like you suggested, I wouldn't have mentioned it here since I'm also open to remove animations from it anyway. So my apologies. :P  I actually like your HairStudio Vol. 1 pack as it's a real value if looking for versatility on male hairdo. :D I also just visited the related forum thread you suggested and saw some nice hairdo variations. The hairdo design I did was actually for a male toddler and I tried making it look as closely as possible to the actual person generated in the Headshot plugin. Thus, I've lost control and used a bit more hair elements than normal having no prior experience with this. Thanks for taking the time to reply! :)

Hi Wilby & Everyone else,

I just came accross this discussion and I'm sorry to hear that you have (performance)issues using HairStudio Vol.1. The main reason for the perfomance problems might be that Softcloth Simulation is enabled for each hair element by default in iClone. I couldn't find a way to disabled it by default when I created the pack, so I suggest to manually disable Softcloth simulation for all hair elements that doesn't need it. 

I also totally understand Kelleytoons' point regarding the components and my initial idea for HairStudio was to provide a most versatile approach to create many different styles with just one pack. I definitely see the problems here and will try to provide an update for this asap - and I will also take this into consideration for possible future packs.

Thanks a lot for letting me know and sorry again for any inconveniences caused. Please also feel free to post your feedback and suggestions in the corresponding Forum Product Threads (e.g. CC3+ HairStudio), so I don't miss any important feedback ;).

Ok Peter, will try that route if I experience performance issues again. Thank you! :-)
By the way, how about those "unverified certificates" for the installers? Are they really that way? Can they be changed to "verified" for security reasons?

Thanks for explaining more. If you are now getting better performance (and improved stability) then of course leave your settings as they are. My own personal experience of customising the Nvidia Control Panel always led to a reduction in performance, so I now leave everything at default and I get great performance even on lesser powered hardware. It's something to consider if you continue to suffer poor performance in other areas.

Ok, I will try merging more props & accessories to see whether I can squeeze some more extra FPS. I wish some tips on how optimization works in iClone 7 for related content were included in all those official tutorial videos I've watched. Even a mention of bits and pieces of info would be valuable. But it felt like a majority of them were made more for marketing reasons rather than delivering quick but important learnings to newbies and potential customers. :P  A newbie to the program would definitely encounter a road block creating his first animation by using unoptimized character hair. :laugh:



I am guessing Tokomotion's Hair Studio - Vol. 1's hair were designed to produce bald spots by default. So I had to use more layers than usual to cover them up for one character. But it's ok, since the hair is for male characters that is not the main focus in my video, I don't mind not animating it for now. Thus merging it as an Accessory is acceptable for me on this current project I have. On future projects, I might just need to separate the project file for any single main character that uses it if I need the hair to be animated. Then again, maybe Tokomotion can provide an update which adds some more "strategically placed" hair elements to easily cover bald spots with the use of less layers -or- just tips on how to do that with less layers if I miss something. :D

That's strange. I haven't customized my settings before the Nvidia GPU issue happened. It's only when I customized them for iClone 7 with separate profile in Nvidia Control Panel and some settings maximized that I haven't experienced any hangs or reboots when using the program so far. I am reaching 20 FPS now with one character's hair merged as a single accessory. I think I've determined the hair are the main cause for the slow down as when I remove them, my FPS jumps up significantly. But will try to merge more props & accessories to hopefully gain additional FPS.

It still wouldn't hurt for you to merge those props into one (those jewelry pieces).  Even with two characters in a scene you ought to be able to get more than 30fps (when you remove the hair).  As always, you want to understand ALL the processes involved in iClone.

(And while I hate to knock any private developer (and I like Tokomotion, particularly his avatars), hair should NOT have that many components to it - not if it's designed to be animated.  There really isn't any need for it - there are some tremendous hairs out there that do it with only a layer or two.  Someone who needs more probably doesn't understand how to create poly hair for animation).
