several plugins missing

[Laura Fischer]

Hello, I am just started to use R25 for modeling. I used to model since R18. But I am facing one issue. Any model I make in R25 when I try to open in an older version like R19 or R21 I receive these message before opening the scene: several plugnins used in this project are missing. saving may cause loss of plugin data! plugin 'magic bullet looks' (id 1054755).
One thing, I made the most simple scene in one project using R25. Just a Cube, only a Cube with no materials, no plugins, light, effects, nothing...just this Cube and when I try to open this scene in R19 and R21 I do receive the same message: several plugnins used in this project are missing. saving may cause loss of plugin data! plugin 'magic bullet looks' (id 1054755).
Why it happens? I usually send projects to my clients and some of them have old versions of Cinema 4D. Will they have any problems using my projects made in R25? Or they just have to click the OK button and keep on working? Because even if I save a project (original one made in R25) inside R19 or R21, when I reopen the project in R19 or R21 I do receive the same message again.

Hi Laura Fischer,

The Magic Bullet Looks is software that was added to Cinema 4D. Going back a few years is always problematic, as tools have been added to newer versions naturally.

Your question is general, meaning I would need to list a four-digit number of functions, tools, and objects in R19 already and what they were not in comparison to R25. Since those release number combinations can easily create over a hundred combinations, that would take a few days per pairing. That is not possible to provide here.

R19 was released in the Fall of 2017. If you can access R19, open the file, copy everything from the Object manager, open a new project, and copy things into it. Since you mentioned modeling only, timeline and render settings don't matter. Does it look OK?

As long as we talk about modeling, the safest way is to export the model in obj or fbx and share that with your client, they can send you the R19 file back, and you can check if they got everything OK.

One side note, this forum is for Site Issues only. Please remember this; thank you. I will move this post to the Q&A forum.

All the best
