It depends on the modeler you use. Here we offer support for MCreator the best bet would be to ask on the forums of the modeler you use. We plan to integrate a modeler with MCreator in the future though, but for now, you need to use an external modeler that supports this.

This is the first time I hear one is using thermos from model making. But nevertheless, I can't really help there, I suggest you to ask the authors of the model maker you use.
