Importing .OBJ Model Doesn't Show Textures

I have a custom block model that has a UV map and a texture, made in Blender. The texture is also part of the material. When I import it into MCreator, I don't get a prompt where I get to change the texture. In-game, the model looks fine, but the texture doesn't show, it's just gray. I've tried changing the material and other things but the texture just won't show up. Does anybody know why I don't get a prompt to select a texture upon importing it?
