Vietnam Tangent-Space Normal Bake

Last crawled date: 7 years, 1 month ago

Nothing very new here but should be of interest to Bmf. I have been following his tutorial about using NASA satellite date for elevation maps, thought that Der-On's Tangent-Space Normal Map blend file would be a good match for this stuff, and yes it definitely is a good match. So I am sharing it as a thank-you to Bmf.SRTM NASA-based Satellite data for Vietnam derived & attributed, so must be CC-BY-SA.Or at least that's how I interpret their licensing requirements for derived works.If you have used too many vertices in your modelling, you can try to reclaim a few with a Decimate modifier, but the Displace modifier seems to create non-Manifold problems. These seem to be resistant to Edge Split modifiers, the easy fix is to use a SubSurf modifier. But this doubles (at least) the vert count - I tried a decimate modifier with this quick fix but my attention span is not long enough to know if it will work or not (I went for lunch and when I came back it was still churning away so I killed it).The easy solution (but not always the best) is always to add more verts so here is another way to get the appearance of more verts so as to have some left for particle systems.All textures should be packed; there is a use note inside; Blend file is compressed.
