Previously, when importing models, p5.Geometry vertices were being reused whenever a vertex position + material gets reused in the OBJ code. However, vertex position + color alone are not all that's included in p5.Geometry vertices: it also includes texture position and normals. By not accounting for this, some vertex texture coordinates were being collapsed, leading to interpolation of textures and normals where there should be a seam.
