@Tristan: I studied computergrafics for 5 years. I'm making 3D art now since about half a year fulltime, but I had some experience before that. Its hard to focus on one thing, it took me half a year to understand most of the vegetation creation pipelines. For speeding up your workflow maybe spend a bit time with the megascans library. Making 3D vegetation starts from going outside for photoscanns to profiling your assets. Start with one thing and master this. @Maxime: The difference between my technique and Z-passing on distant objects is quiet the same. (- the higher vertex count) I would start using this at about 10-15m+. In this inner radius you are using (mostly high) cascaded shadows, the less the shader complexety in this areas, the less the shader instructions. When I started this project, the polycount was a bit to high. Now I found the best balance between a "lowpoly" mesh and the less possible overdraw. The conclusion of this technique is easily using a slightly higher vertex count on the mesh for reducing the quad overdraw and shader complexity. In matters visual quality a "high poly" plant will allways look better than a blade of grass on a plane.
Is this not like gear VR or anything else
During GDC 2017 Jaap van Muijden from Guerrilla Games did a little presentation, talking about the ‘GPU based procedural placement system that dynamically creates the world of Horizon Zero Dawn’.
Although we do not have the video recording of the talk, we do have a presentation, which was shared at the official website. It basically shows how some very complex algorithms can work together to build an amazing open world ad fill it with assets in an incredibly realistic and artistic way.
Although this is more of the technical presentation it does show a lot of stuff done for artists. For example, Guerrilla Games showed how every aspect of the world, although generated by a clever algorithm, could be easily modified by an artist. They could alter the placement logic and work with hand-authored assets.
Plus they’ve showed how they’ve worked with the world production. You can see various types of maps coming together to achieve the final result in DECIMA engine. ‘The GPU-math’ basically took care of all the placement, which to our surprise gave the game a very organic and naturalistic look. The fact is, that computer-generated ‘rough’ landscapes in Horizon Zero Dawn actually look so good that users are making screenshots and post them online, praising the craftsmanship of the studio. It’s amazing, if you take into account that only 3 people actually made the nature assets for the whole production.
It’s a little frightening. Does that mean more upgraded stuff like ‘Deep Mind-powered landscape generation tech’ could actually make better spaces than an environment artist? Tell us what you think in the comments.
