Issues Importing Disney's Magic Kingdom Model from Cinema 4D to UE5 through Cineware

Hi everyone! I’m at a loss, and would really appreciate some guidance in figuring out the issues I’m facing with the Cineware and Datasmith importers for Cinema 4D projects.

I purchased a model of the Magic Kingdom hub and Cinderella Castle on Turbosquid. It’s a native C4D file, and I had to spend a couple of hours reversing normals so that everything would appear correctly in something like UE5. I’ve been trying for days to get this imported into Unreal Engine correctly, and I can never get it to import successfully.

It will import, but then there will be missing geometry, flipped normals (even though they are correctly orientated in C4D), and sometimes geometry is changed. I’ve attached photos showing C4D vs UE5.

I am newer to C4D, but have been using UE5 with Sketchup and Datasmith for a little while now, and have never faced these problems. Any help would be appreciated.

Missing textures on the umbrellas and the railings are incorrect.

Many textures are incorrect here, two main flower bed sections are missing (a mirror of each one there, I believe), and the center circle is missing most pieces.

These side turret pieces are missing a lot of geometry and pieces to the buildings attached to them. You can see the entire blue roof missing.

Here the stage is now missing textures, but it is also missing its right platform. The platform has pieces of it in the air randomly.

This one is so strange because it moved and rotated geometry in really interesting ways. These aren’t normal 90-degree changes. They are odd numbers on every axis.

Overall, none of the railings appear as railings anymore. They ignore the masking maps they have. And It seems that anything that used a “cloner” (I apologize if that isn’t the correct term) for symmetry or duplicating doesn’t appear correctly.

For context, I am using UE 5.3, Cinema 4D 2024, and the newest version of Cineware for UE.

Thank you so much for reading through this, and I will happily answer any questions you have. Thank you so much!

I can’t advice you on cinema 4D but some issues sound familiar.
Some models like the roof and the fences might not have a thickness and will only display to the side the normal points unless your shader (UE material) has “two sided material” ticked.
The odd rotation and location displacement could happen when location / rotation / scale is not applied properly. They should probably be zeroed on all objects in your 3D software (cinema4D?). In Blender I see such problems when people transform things in object mode instead of edit mode, causing the base transformation to screw up things later.
