Often, this creates a more angled slope on any area with a steep edge, which is great, however, doing this creates a "fake" height map, so I (when needed) mix this back in with the original photogrammetry height map to get an optimal result. #TESSELLATION ARTIST MANUAL#Some are completely manual (like clone stamping areas) and others are a bit more automated (like generating a new height map from the normal map). Since a displacement texture can only push outward, if you have a brick that has a flat sharp steep edge, then you get a lot of stretching, so I use a mixture of methods to fix this. The other thing that I often fix manually is very steep areas of the surface. I usually start by trying the automatic solution (if I get lucky, it might get me 70-80% there), but more often than not I do this completely manually inside ArtEngine or Mixer, it all comes down to the time you have and the quality of the final result you want. In these cases, automated solutions either do a poor job or you end up spending a long time trying to find the magic settings to get a good result. You could use longer exposure and a tripod, but that adds significantly more time to capture (and might add noise), so it’s something that needs to be kept in mind.Ī lot of the manual work is making the material tile well, I find automated solutions work quite well for noisy surfaces like small stones, noisy tarmac, etc., but often look pretty poor for anything with a clear pattern or structure. If you are trying to do photogrammetry of something indoors with low light, a flash is essential to get good clean results in a decent amount of time. The other big advantage of using flash is that it gives you a flat-lit albedo texture when capturing very rough surfaces, this is the biggest advantage a good flash provides. If I make very rough surfaces like stone walls, I generally just use a shade, or if it's overcast, that works well too, but the light gives you much more areas that you can capture. My main issue with this light (Riko 400) is it's large, heavy to carry, and the flash is very bright, so not something you can use discreetly (e.g., in busy public spaces). I use cross polarisation to remove as much reflection/specular light as possible as this gives cleaner scans (particularly on smoother/shinier surfaces) it has its limits but does help a lot with certain objects/surfaces. As I mentioned above, I have recently purchased a Riko 400, which is a 400-watt ring flash, I have only used it on one of my materials shown ( the first material in this link ), this allows me to capture scans in any conditions (except rain, which is unfortunate as I live in Scotland). ![]()
