| Mar 29 at 19:02 | comment | added | Luca Ghilardi | Indeed, it is what I'm using. I want to use high-resolution images for my model. Those are available only with the LROC's NAC (narrow-angle camera). Unfortunately, I don't think they have done many passages in the same areas; therefore, the images are in a specific illumination condition. I tried to use the WAC color map for the whole moon, but the details are not great for areas that are only a few km wide. | |

| Mar 22 at 18:55 | comment | added | Luca Ghilardi | I have the height maps and the real images. The issue is that those images are taken at precise illumination conditions. I was wondering if it was possible to have an effect similar to the real images (the white areas exposed to the sunlight) with a dynamic illumination. | |
| Mar 22 at 0:04 | comment | added | Lutzi | The white areas around craters are recently exposed material which hasn't darken yet. Some craters are young (bright), some are older (dark). If you want to go for a realistic look, it would be easier to use NASA color maps and height maps as Martynas Žiemys said. Otherwise, you'd have to build a somewhat complex shader to reproduce these colors. Depends on your needs. | |
| Mar 21 at 23:37 | comment | added | Martynas Žiemys | You should be able to find real images with corresponding height maps online. NASA's website probably has loads of material on this in high resolution. So you get albedo and displacement maps and that's pretty much it. You can probably get away with a diffuse shader. The misunderstanding about lighting being a property of material will probably have to go though. Not really sure what you could possibly be struggling with here. Maybe providing the context would help. | |
