S3D coordinates, conning tower

smm · 11-27-23, 02:44 PM

Hi,
I'm trying to export Gato sub via S3D-> Blender -> UE5. I exported most of the things ok, but have real trouble with conning tower bits and pieces coordinates coordinates.

Some items work ok, but some I just can't get going.
At the highest level, 2: Node Chiosc_NSS_Gato_04, there are already some coordinates set:
X: -0.01423397 Y: -0.00610776 Z: -0.6417547
Then, the conning tower model, 11: Node Chiosc_NSS_Gato_04 has another set of coordinates:
X: 0.0000000268221 Y: -0.2514915 Z: 0.1076843

And then the items themselves - like 44: Node B Capsule Munitie, which has XYZ esentially 0, but has 180deg rotations along X and Z axes. Except that it places the mesh nowhere near where it's in S3D. Same with Antenna.

Also, when I tried to get in the instruments, I'm confused. Instruments have their own coordinates (in sensor_sub_us.dat file), but there are also attachment points in the conning tower file itself (say 74: Node cfg#I01_NSS_Gato_Tower_04).

I could, of course, just place the meshes just somehow, but it feels wrong.. So any advice on how to calculate the position would be really welcome!

In Blender, I'm trying to follow the hierarchy from the obj file, and am using delta transforms.
