Hello everyone, I'm having issues with Blender and Substance Painter. When I export a 3D model from Blender to Substance Painter, three errors occur:

1. 1. Substance Painter is ignoring the existence of some red seam lines;
2. 2. A group of faces is stretching the texture;
3. 3. Other groups are applying the texture horizontally and with different sizes.

I'm a newcomer to this world, so please forgive my ignorance.
