I know exactly which texture those meshes should point to. I don't use vortex so I can't tell you which mod is adding it but the texture you're looking at should be textures/architecture/whiterun/wrbrazier01.dds, and all those meshes do use that texture, including the mortar and pestle. If Vortex has a file system browser, try looking up that texture path, or look it up in whatever folder you have your mods being installed into. But again, I don't use vortex so I'm not quite sure how it installs your mods but if it's like NMM it would all be installed into one folder. Edit: I went ahead and downloaded both mods to see for myself and neither High Poly Project or Illustrious Whiterun seem to replace wrbrazier01.dds or wrbrazier01_n.dds, so I would try deleting those files and seeing what happens.
