I had read previously that anisotropic reflections work only in World Space for the time being in Corona but I’d imagined that this would solely govern the orientation of the effect and that the actual reflection would still spread along the real surface of the object. I’m not sure if I’m judging this wrong from observation but from the tests attached it appears as though anisotropic reflections don’t adhere to an object’s surface. On the undulating curtain surface reflections spread in the horizontal direction are becoming completely lost. Anisotropy is also strongly affecting the appearance of material glossiness and reflectivity amount. The same problem doesn’t seem as apparent on the sphere primitive. Is it simply that the geometry of the sphere is kinder to the shortcomings of World Space anisotropy than that of the curtain behind? Basically is there anything I can do to make anisotropy work on objects such as the curtain or should I give up on this until Object Space anisotropy is possible in Corona? All the examples have the same material apart from the anisotropy values, which are: 0, -0.1, -1, 1 (Sorry, I’ve labelled the file name of 2nd attachment wrong. It is -0.1) Thanks ![ANISOTROPY 0.jpg](https://europe1.discourse-cdn.com/chaosprd/original/3X/3/5/35695cc8aa250e12bc7110787172042af66e1390.jpeg) ![ANISOTROPY 0,1.jpg](https://europe1.discourse-cdn.com/chaosprd/original/3X/3/2/3258239363cb996e9f65b16926482011abd464c7.jpeg) ![ANISOTROPY -1.jpg](https://europe1.discourse-cdn.com/chaosprd/original/3X/7/a/7a6e5fe8d8fb06ff073e67f2eeffbf9ceb1bb149.jpeg) ![ANISOTROPY 1.jpg](https://europe1.discourse-cdn.com/chaosprd/original/3X/b/f/bf75c825daa88590783140721b405e68e2d48295.jpeg) ---

Sorry but anisotropy is still a WIP feature. We have recently added it here: [https://coronarenderer.freshdesk.com/support/solutions/articles/5000516180](https://coronarenderer.freshdesk.com/support/solutions/articles/5000516180) There is also this topic: [https://forum.corona-renderer.com/index.php/topic,3957](https://forum.corona-renderer.com/index.php/topic,3957) So for now the solution is to use some kind of walkaround like bump maps or modeling surface. ---

Thanks, yes I’d read this previously. I just hadn’t appreciated the entirety of the limitations this presents in practice until I started trying to work with it. Is there any estimate of when object space anisotropy might be developed/implemented? I think the last word of it I’d seen in a thread said it wouldn’t be until 1.0 was out. Any more clues please? ---

Currently planned for 1.1 (in about a month) ---

Brilliant, thanks!
