Strange configuration of materials in objects downloaded in Chaos Cosmos update

[Chules]

With the april update of Chaos Cosmos with the release of the latest version of corona c4d macOS, chaos cosmos objects are downloaded with a canl of SSS material that makes render times increase a little bit (actually it increases a lot the pre-calculation and the render only a little bit in print) and the interactive render times increase a lot, being impossible to use it.
I have made a comparison with the same objects downloaded 1 month ago, and the same old object does not have the SSS channel in the materials and the same object downloaded now has it. This has happened to me in a scene with several vegetation objects and the scene has become almost impossible to handle with interactive renders.
I think it's due to a bug and it's activating this channel in materials that don't need it. I have tried to go object by object and material by material deactivating this SSS channel and when I do this exercise cinema 4d closes with an error in the corona plugin.
Is it possible that this is a bug and not a problem with my equipment?
My computer is macOS 15.4 Studio M1 Ultra. I have tried it on other computers and the result is unfortunately the same.
I hope you can help me.
Thanks for the support and this wonderful render engine, thanks for not forgetting the macOS users.
Suggestion: study the options of implementing rendering through chaos cloud. Chaos Vantage for macOS.

Can you let us know the error that C4D closes with, and send us the scene (best done via ticket at https://support.chaos.com/requests/new), and any generated minidump, see https://support.chaos.com/hc/en-us/articles/4648898278545-How-to-report-issues-C4D for where to find / how to capture one of those.

While the material set up looks a little odd, it should have no effect on render times because it's mapped and the value being sent in from the map is zero. I tested rendering with it as the material comes in (nothing in the scene but a plane, sun sky, and these jugs) and it was 11s, and I then disabled SSS in the material, and render time was 11s. I then re-enabled SSS and removed the (empty/black/zero) mixture shader map leaving the Fraction at 100% now rather than zero, and render time was 38s. I changed Fraction to 0%, and render time was 11s. So basically a Fraction of zero is the same as not having the SSS block enabled in the shader.

This means it should not be causing you a slowdown. And of course, it shouldn't be causing a crash either, and indeed I was able to change the SSS for these objects just fine :) I am on Windows I should note.
