Hi there,

I’m trying to make an scene in a cross section. I’ve added an image to explain what i’m trying to. I need to create a scene like this but i need to show the movement of the submarine while cross section stay it’s place. Like i need a scene in a bounding box. How can i achive this? I tried to find a tutorial about it but i can’t. Actually i can’t figure out how to search it

Hi emre.mtl,

Please have a look at the file below:

Is that what you are looking for? The idea is that only what is seen after the camera view passed anything transparent, the blue object will be visible. If not in the cube, it is not rendered. Please check the Compositing-Tag for more details. The Tag is on the blue object.

Another idea would be to camera project a rendering of the cube’s alpha onto the ship. I would need more information, e.g., if the camera is animated or not.

If you can set up the camera and ship animation in the provided file, it will allow me to be more specific.

Cheers

Hi Sassi,

Thank you very much for your detailed answer. It’s almost what i’m trying to achieve but i need to see only capsule. Camera will be steady.

Thanks for the feedback,
Here are three versions, just the capsule limited to a cube.

One works with the Seen by Transparency [02]. The next use Boole and is my least favorite, as it needs some attention [11]. The third one creates a 3D alpha channel [21].

The Formula Shader might work, but I think file [21] is more intuitive.

Let me know if there is something that doesn’t work for you.

All the best

That’s what i need exactly. Thank you for being so helpful. I really appreciate it.

Great, emre.mtl, thanks for the reply.

You’re very welcome.

My best wishes for your project
