I have a problem opening a TM file in the unreal engine even though I have installed all the plugins that allow them to be imported. The error that appears informs that the format is incorrect. In the case of datasmith saving, the file opens but not with all textures, and in addition it is very slow and the fps number drops to less than 5, despite the fact that the largest photorealistic huge epic games projects run without any problems in 4k 60fps.

Thank you in advance.
