I can't reproduce it. I see one mesh light in you scene. Changing any attributes, like intensity or exposure works fine in the IPR. Is this crash new in C4DtoA 4.5.1.1? Could you please describe the steps to reproduce? Does the Autodesk crash report dialog pops up when the IPR crashes?

Hello Peter!

Was not new. Well, it crash also when I’m using without care if is gonna work or not, but always when I try to change exposure or intensity. The crash report pops up, and I write the same as the title of my post.

Thank you.

Thanks, I see the crash reports, they can give me a hint. I'll investigate and let you know if I find the problem.

Thank you!!!

Unfortunately, I still can't reproduce your crash. The crash reports point to light linking, which is weird because I don't see any light linking setup in your scene. I'm kinda lost at this point. So you just open the scene you sent me (prova.c4d), start the IPR, change intensity or exposure on the mesh light and that's it? You have no motion blur enabled or any special setting in the IPR, right?

Hey Peter, 

I don't know if you get my answer. I sent a simple scene, only with the light that crashed the system. Here is the complete scene.

Thank you.

Thank you, I managed to reproduce the crash with the full scene and found the problem. It will be fixed in the next release.

This should be now fixed in C4DtoA 4.5.1.2.
