Hello everyone:
I was trying to convert transport fever's mod by TPF1 --> TPF2 Konverter by EAT1963 on https://www.transportfever.net/filebase/index.php?entry/4809-tpf1-tpf2-konverter/
I will have to say that mod has been successful, since that the it can be successfully open in the model editor. However, it will still crash the game instantly when that model was shown with: texture load error: file not found: res/textures/ui/models/placeholders/missing_signal.tga
In addition, this error only applies to converted transport fever mod while converted train fever mod works smoothly.
Thanks to everyone who tries to answer my question.
