C4D R25 crashes when start rendering

[simon_eugster]

I have a serious issue with Vray5 rendering:

I got a new Mac Studio (M1 Ultra) with 128GB RAM, macOS Monterey 12.4
Installed C4D R25 and V-Ray 5 (v.5.20.05)

Following happens:
1. I open a project (pretty easy, only 25MB in geometry and about 12 simple materials)
2. Open V-Ray VFB
3. Start "interactiv rendering"
4. Everything fine
5. Start "Render"
6. C4D crashes without warning and without any report in the Vray-Buglist-folder

With a bigger file (250MB geometry, 40 simple textures) I have this issue too:
- Start "Render"
- It starts "preparing scene"
- as soon as it comes to "building light cache" C4D crashes
- C4D crashes even when I start "interactiv rendering" in the V-Ray VFB

Rendering on the chaos cloud (same files) works fine!

What can I do? Is this a known issue?

Hi Aleksandar, can you please let us know if there is any issue with the hardware setup? We plan to add a MacStudio very soon and it will be useful to know if there are specific issues or if this is only a user error.

Hello sirio76,

It seems like the crashes were caused by the low max file limit. Increasing the limit seems to resolve the issues.

This topic has been discussed a few times on the forum here, here, and here.

Hello simon_eugster,

As stated in this forum post, we just released -Ray 5 for Cinema 4D - Update 2.6. With it, we have raised the max file limit on MacOS to improve stability (along with other bug fixes and improvements). Please download and install the build from here and let me know if it helps with those crashes. Thank you.

Hi Aleksandar

Thank you very much for fixing the problem and the Update. I've just tested the Update with a file that always caused crashes. It works now perfectly! Well done and again – thank you!
