Hi gordryd,
too bad, it doesn't work for me even if I set Illumination = 0 (or slightly higher) for the cylinder.
I'm afraid I'll have to give up trying with the "beamer". Despite everything, thank you for your help.
Best greetings, Ulrich

Hi, Nirwana & nick_tregenza,
You are certainly right when you point out the limited capabilities of iC & CC.
I have installed Blender and Unreal Engine for testing. For an 80-year-old hobby user, these systems take quite a long time to learn. I don't have that much time left.
Cinema 4D is also not uncomplicated and costs a lot (at least here in Germany).
Thanks for the advice though.
Best greetings, Ulrich

That's the problem with society these days - we take far too much for granted.
80 years old -  major kudos to you...!!! It's never too late to learn anything (except maybe skydiving..lol), but that's seriously impressive!
You put a lot of people to shame - and I am glad that you are doing so! :-)

I thought I started late - I'm in my 50s, and only started learning about 15 years ago - but you are living proof that if you want to learn anything badly enough, there is nothing that you cannot do!

Lesson learned - and I apologise for assuming that you were a student out of school...!

Happy to help out, if I can - but I too, have only just picked up CC and iClone recently (within the last 2 years), so we can probably learn from each other...  :-)
But if you wanna know more about compositing? I can definitely help out there!

Cinema 4D is also not uncomplicated and costs a lot (at least here in Germany).

Yes, Cinema 4D is not free (not just in Germany), but that is true for most capable 3D packages with the exception being Blender (I don't consider DAZ a complete package like Blender), UE is somewhere in between but--so I understand--getting to be more capable all the time. However, I was not suggesting that you use C4D. It is merely what I use, because I started with it some 20 years ago; today, I would probably also consider Blender. I was just pointing out that you need an additional 3D tool that is more fully-featured than iClone if you want to create stuff like this projection. I'm pretty sure the same effect can be achieved in Blender, but since I don't know that program well enough, I did not use it to demonstrate this effect.
