Thanks Luvs, I've seen the BBC documentaries. I guess these are those. Not sure, as the site is not available to me (Europe).
Thanks René. Nice refs. I've been thinking about that too, but I hate to do much editing on maybe a thousand reindeer. I used a RGB+black mask for at least 4 pops, not to get them overlapping (I wouldn't really know how to mask 8 pops off eachother in a simple way), and a stretched and warped, ridged, hard fractal as flocking lines. Also just a bit (40º) of rotation. I could easily paint a simple tif with some flocking lines, but the animals still have to rotate such that they more or less follow eachother, and that's the hard part. Rotation should be warpable and by input too. But you are of course right about the too even spread. I wil attend to that, while I will also add 2 more poses.
