Hi everyone,

Sorry to bump the topic but I need your help one more time.

First of all I tried the tutorial above and DLSS didn't fix the issue with the hair physics for my character. Actually the guy who made this tutorial shared a pdf where it talks about this issue and confirms that hair physics doesn't support Temporal Sampling.



So I made a test with Spatial Samples at 64 and leave Temporal at 1 plus adding the console variables suggested in the Unreal official documentation and the result is fantastic.

However I'm now facing an new problem. This time with subdivision mesh.

When I activate the subdivision mesh in iclone to get a smoother character the hair goes crazy again once imported into Unreal but this time it has nothing to do with movie render queue cos the issue happens as soon as I hit the simulation button.

If I keep the subdivision mesh off everything is fine but when it's activated it's a mess.

OFF


Subdivision lvl 1


Both times I made sure to adjust the collision also I worked on the ClothingData_1 just like explained in the official tutorial of Reallusion but even after many many tests I couldn't manager to fix it. :crying:

Nice, thanks a lot raitan for sharing this.

Thanks! I had heard from Markom3d that it was free, but I never saw the free button til now. I have it installed and running! Woo hoo! Thanks.

@raitan , cool stuff ! 👍

Live Link is free for Indies ! https://www.reallusion.com/iclone/live-link/unreal-engine/indie.html

And Control Rig is coming for CC4 ... 

I am thinking of buying LIveLInk, but it is hella pricey! $745...yikes. Anyway, I only want it because I can't tweak animations or poses that I export from Iclone8 into unreal. Or can I? Besides livelink, is there a way to build a control rig to allow for animation tweaks once you import the cc4 fbx into unreal?

Here is an example of using DLSS with hair physics in unreal 5.1.1 
This render took less than 5 minutes.

Here is the link to get dlss...

and here is a brief tutorial on how to use it

I had the same problem, and I got nowhere with answers. But I learned about the Nvidia DLSS/DLAA plugin that is a plugin that works with movie render queue. It upscales and renders super fast--I mean real time fast. I used to render with anti-aliasing 1 64 and the console variables. A one minute animation would take about 2 hours. With DLSS, that was down to 4 minutes or less. And guess what? The hair physics works flawlessly. https://www.youtube.com/watch?v=frQOAptM6Yg

Awesome, thank you so much for your help guys.
