I do not have to send you a scene. Cinema 4D already crashes when I create a new empty scene and create only one material, then activate the bump channel and select a noise shader. Immediately the crash occurs.
I have attached the bug report, of course.
Thank you, Allertaler. I created a new empty scene, created one material, activated the bump channel and added a noise shader to the bump channel. There is no crash for me, sorry...
There must be something you are doing different or it could be caused by your system - Cinema4D version, OS version, SW, HW, ... To rule out the first thing, it is important for us to be able to reproduce exactly what happens when the crash happens on your PC. This can be done either when you describe precisely what you're doing or by sending the crashing scene.
Sorry for not being able to debug it with the information that you provided, but as you can see, neither me nor synolog were able to reproduce this.
