All about dforce

First I find myself a little confused between dynamic clothing and dForce. Seems to me that within DS it is possible to creat a dynamic cloth using a plane and by giving the plane many sub divisions affect how it acts in a simulation. I know because I have done this and it does work for me albeit very slowly, but anything more ambitious simply crashes my machine. So for example if I follow the tutorial video on dForce the final act of draping cloth as shown in the video threatens to exceed my remaining lifespan by some considerable amount. Or my machine simply has enough and crashes.

This brings me to the conclusion that to use dforce effectivley I may have to upgrade my current machine ( I will post the specs for this machine at the end of this post) and purchase something capable of taking advantage of this technology.

However, I may well be wrong, I very often am, so is there something I am missing, if so can anyone give me and possibly others some advice on this subject. It would be nice to find some other tutorials on the subject too.

My machine specs are on the attachment...

    What graphics card do you have?

    Sorry missed that info out due to dimness...

    AMD Radeon HD 6770M 512 MB

    As far as I am aware thats the full spec for my rather old machine, some life in the old boy yet though, bit like myself i suppose. As for info and advice, i have found a tutorial on deformers, again, not exactly intuitive and again, bit like watching paint dry, so looking forward to some kind soul revealing all, or at least letting me know if I need an upgrade and if so, just what would do the job efficiently....

    Thanks

    That doesn't have a lot of memory for the work, and if it is as you say old it may not support a new enough version of OpenCL.

    your gfx card doesn't have a particularly high spec for large amounts of colliding geometry, you could try use your cpu instead, from what I read mac should be preinstalled with opencl drivers.

    under the simulation tab > advanced there should be a drop down for devices, if your cpu doesn't show up you may need to figure out how to install drivers for the cpu but I have no idea how to do that on a mac.

    Struggling a bit to figure out whats required.

    Looking at sim tab/advanced I see open cl and my graphics card listed. So where do I go next? It would be at least conclusive if someone could say your crap machine doesnt have the smarts to use this technology, I may be upset but hey, thats life. Then I could consider investing in something that will enable me to use this tech, and in that case perhaps someone might advise me of the best set up to achieve this result.

    This might mean at the high end custom built machine, which would require advice on CPU, graphics card, HDD, power supply and all the other hardware to put together a machine that would work and estimate the cost of doing so.

    Have attached SS of sim tab...

    so its a bit small to see but where it lists apple ati radeon hd 6770 M, that is actually a dropdown and if your cpu is opencl capable you should be able to select it there.

    Thank you so much skinklizard, then my CPU is definitely NOT open capable. I am assuming that this obviously precludes the need to install drivers and probably means I need to get me a better chunk of computer. That being the case, I can have one built to my own specs by a colleague, can anyone please advise me the best components available to enable me to use this tech at a performance level that keeps me awake.

    I need to check out the costs involved, I would not be going for an off the shelf Apple mac because I have one already...

    Seeing as no one else has weighed in on this yet, I'll give my opinion on minimumish specs for general daz studio and graphics work, also one other thing you can try to get dforce working on your current machine.

    The intel cpu you listed should have built in intel hd graphics which, if you figure out how to enable on your mac and install the drivers for, you could use for dforce. A quad core at 2.7ghz is still going to sim pretty slowly though.

    For specs, I would suggest an Nvidia card preferably an rtx 20 series but a gtx either 10 or 16 series works too, with a minimum of 6 GB of vram (8 would be better), I'm just barely surviving on a gtx 970 with only 4GB of vram and it makes rendering on the card pretty difficult for anything more than simple scenes.

    for cpu I've heard good things about the AMD Ryzen 5, 7 and 9 (3000 series) if you choose intel instead get a 9th gen equivalent i5, i7 (there may be newer now though)

    I would also suggest 32 gigs of ram, I've yet to max that with daz studio only but have done so with both blender and photoshop seperately.

    If you're not interested in using Iray in Daz Studio for your renders then you could look at the AMD graphics cards instead, also apparently Apple and Nvidia are not playing nice at the moment so for Iray you probably want to run Windows or Linux (I have no idea about the linux implementations though) 

    I would do some research and see what other people are using and how well those systems perform for the price, a lot will depend on your budget too.
