How to swap to TFT world editor?

[Dr.Sinner]

I wanted to try out things in the world edior for the first time but I'm having problems importing custom models, they are invisible with a shadow. I read that this is because of the RoC world edior? I used both RoC and TFT keys when I installed so how can I swap to TFT world editor or do I have to reinstall and put only TFT keys? Does the version of the editor not matter and the problem is something else?

Edit: I found that I am actually using the FTF version. The issue is the pathing of the model.

Can you link the model you'd like to import? It sounds like you might have used the wrong path or you're missing a texture.
