UE_FlavienP · July 14, 2022, 1:28pm

Are you able to share the C4D file with us?
If yes, please give me a link in private.

zpghost · July 14, 2022, 1:41pm

Unfortunately the file is private, my friend the import is fine, the problem is not in the file

zpghost · July 14, 2022, 1:51pm

now it just hangs at this stage

UE_FlavienP · July 14, 2022, 10:03pm

I successfully imported 4 different C4D today.

Do you have cineware installed on your machine?
Did you previously replace the DatasmithC4DDynamicImporter.dll with the one from Maxon?

Does your friend has cineware on his/her machine?

zpghost · July 15, 2022, 5:58am

I downloaded 4.26 and uploaded the file there, it took 5 seconds to upload everything works fine. cineware installed. The problem started on 5.03, everything was fine on 5.02

UE_FlavienP · July 15, 2022, 10:55am

I understand it is a new issue on 5.0.3 but I cannot replicate at office.
I am trying to understand better your os environment. Did you replace the dll as they say on their website? (not that you should do it)

zpghost · July 15, 2022, 1:28pm

i did it but it didn’t work

Jimbohalo10 · July 15, 2022, 5:51pm

Hi @zpghost @UE_FlavienP,

The error is from python 3.9 not containing the function it would appear to be coming from the ssl.pyd which has changed.

ssl — TLS/SSL wrapper for socket objects — Python 3.10.5 documentation

Changed in version 3.6: OpenSSL 0.9.8, 1.0.0 and 1.0.1 are deprecated and no longer supported. In the future the ssl module will require at least OpenSSL 1.0.2 or 1.1.0.

I don’t have python loaded and when I go into Windows Powershell and type python it offers to load python 3.10 from the Microsoft Store.
I wonder if an older version of python is installed causing the error.

Just for the moment could you uninstall python version on you PC and try again because all the exceptions and errors in your log are python SSL errors

zpghost · July 15, 2022, 7:10pm

I didn’t have python installed, I installed it, it showed up in windows cmd. But the installation did not help in any way to solve the problem, I installed 3.10.5

UE_FlavienP · July 18, 2022, 9:01pm

Can you all check if the answer from AKnauerMaxon posted here solved your issues.

zpghost · July 19, 2022, 8:21am

I wrote this line to a file, it didn’t help. I deleted and reloaded unreal, and now when I load cineware it overloads all RAM and crashes:

Hello Zpghost,

I would suggest that you install R25.120 to be 100% sure.
We have not seen this kind of crash before.
Could you open that scene in Cinema and report that bug with “CWUE5” in the subject?
Your C4D file will be treated confidentially.

Thank you!

zpghost · July 19, 2022, 3:17pm

ok, I’ll try to install this version, the problem is not in the c4d file, there is a scene with a small number of polygons, it can’t load all the c4d files, I just downloaded unreal 4.26 and ported c4d there and then I throw the project files into 5 and everything works, but it’s all not comfortable

AKnauerMaxon · July 20, 2022, 7:35am

The Datasmith plugin in UE5 needs Cinema R25.120, specifically cineware.dll and its config files which are installed with Cinema.
You could also try out the CinewareAsset plugin, it allows reimports with changed parameters exposed as takes:
Maxon - Unreal Integration

zpghost · July 25, 2022, 5:30pm

I downloaded this version of cinema 4d, nothing has changed, it still overloads memory and crashes
Is it possible to return to version 5.0.2?

in the error window shows that the small amount of swap file, I increased the swap file to 50gb ssd , the memory was fully loaded for about 5 minutes, the “unreal datasmith”

window appeared, but in the end the error still came up with a shortage of swap file, I write through a translator and maybe i misspelled the term, maybe it’s called virtual memory
