Hi Manuel, perfect - in the Script Manager everything works as expected. Running the code via python tag isn't important to me - I just wasn't aware of this difference ScriptMgr <> PythonTag concerning the execution of the code. Thanks a lot for your solution ! Cheers, Jens

Seems I also forget to mention but please use About Tags and Tagging like so you can mark a specific version.

After a reboot, I'm able to reproduce it again... I will create a bug report and more testing after Season's Greetings & SDK Team Vacation. Anyway thanks a lot. Cheers, Maxime.

Thanks @eziopan and Sebastian for your answers ! So far I searched a way for getting values out of the 3D noise shaders. Starting point was the c4d.BaseShader class but it seems to me that accessing these shaders in order to get noise values is much more cumbersome than using the C4DNoise class and specifying the corresponding noise type as parameter 't' - as @eziopan has pointed out. So: thank you - problem solved ... and sorry, I haven't read the Q&A system thoroughly enough - next time I will mark my post properly. cheers, Jens
