Not getting anything from that link - can just upload the image direct to the forum, easier than using an external link of any sort 😃 ---

The problem is UVW in material. [https://yadi.sk/i/hkF7xxBo3N9YBV](https://yadi.sk/i/hkF7xxBo3N9YBV) The problem appera when the UVW chrckbox is active. ---

Issue when using anisotropy and uvw mapping. Not sure if unexpected. ![aniso1.jpg](https://europe1.discourse-cdn.com/chaosprd/original/3X/c/e/ce81356dc5b58b38c3024ae670232d2f0874dedf.jpeg) ---
