Kexikus 994 Posted December 23, 2018 I'm currently trying to figure out cubemaps. The conversion from a simple folded cube to KotORs format is okay. But I'm now wondering how the cubemap is "oriented" in space. Up and down are obvious but which side is "facing" north? Any help here would be very welcome Quote Share this post Link to post Share on other sites
JCarter426 1,214 Posted December 24, 2018 Should be simple enough to test, let's see... In descending order: bottom / top / left / right / front / back With directions relative to a player facing north. At least for what I tested. 1 Quote Share this post Link to post Share on other sites
Kexikus 994 Posted December 25, 2018 May I ask how you tested this? The reason why I'm wondering is that judging by Darth_Sapiens examples the order would be different: Let's say that 3 is north or front, then 4 and 2 would be switched in your order (5 and 6 are flipped by 180° here). I tried both versions ingame (these are for sky reflections on Taris buildings) but it's really hard to tell whether or not the reflections are accurate. Maybe that's also due to a misunderstanding on my side about how cubemaps for reflections work. Quote Share this post Link to post Share on other sites
JCarter426 1,214 Posted December 25, 2018 I just made a cube map with a different color on each side, then applied it to a cube and looked at how each face changed relative to the viewing angle. That picture looks consistent with my testing. I think you've got it flipped around in your head. Your building and the cube map have opposite texture wrapping. If it helps, imagine the cube map is being wrapped onto the skybox rather than the building. The map is then drawn on each part of the building that's facing that part of the skybox. If you mapped the cube map onto a cube, then you would indeed get two faces swapped, similar to how you get a left/right flip with a reflection in a mirror. 1 Quote Share this post Link to post Share on other sites
Kexikus 994 Posted December 26, 2018 Thank you very much for your help. I had it flipped in my head, just like you said. But I was now able to figure it out. Thanks Quote Share this post Link to post Share on other sites
