Hi,
No idea if it is the right section...
I came back after a while and wanted to set up my game again. (It have been some years)
Now i wanted to bring my boat back to old glory with S3D (adding some details in the Control Room) But everytime i think i am done and want to try it ingame i get a CTD. S3D however shows the changes, sadly the most topics and tutorials about S3D seem to be gone :/
So maybe it helps if i explain how i work on it.
If i open the NSS_Uboat7_CR.dat there is the regular "COMMAND ROOM"
So i added a new node to it, gave it a label, added a model and imported a obj file. The original file seems to be rotated in some kind X axis 0,2 and y axis 300,0 seems to be normal.

So after i did that i added a Material, gave it a label, added a texture map, and an embedded image. So far so good, it gets shown in the CR and the 3d view.
But after i saved it and wanted to try it ingame...nothing i get a CTD in the Mission loading screen.
Anyone who can help me out? I tried almost everything today just to get that to work...but without sucess.
Thanks for reading through all that.
