Broken model textures

With blockbench I made a model and textured it and it all looked great. It was in format Java block/item and I exported it as a wavefront obj. I imported it to mcreator and imported the texture as well. I set it as the texture when importing the model as well as in the block menu as main texture. This all has worked for me before. However I then loaded into the test client and when I placed the block it rendered a small block, pitch black, not even part of my model, in the bottom of the block, mostly out of the hitbox. I am very confused does anyone know what happened?
