Quote from: j meyer on March 05, 2018, 02:59:57 pmDon't know if it is a solution for your problem, but I would try to put a Vector Displacement Shaderbetween the Power Fractal(Warper) and the Warp Input Shader.At least it allows control of the 3 axes.
Quote from: Matt on March 05, 2018, 03:22:18 pmWarp is based on the displacement generated by the warper. Displacement usually happens in only one direction, which by default is vertical.To create displacement along all 3 axes you can use the Redirect Shader and plug 3 displacement shaders into its X, Y and Z inputs. Alternatively, as J Meyer mentioned you can use a Vector Displacement Shader instead. This will do a similar thing but there's a very important difference. Vector Displacment Shader takes colour or scalar inputs (which can be the colour output from a fractal) and converts them to displacement, whereas the Redirect Shader takes displacement inputs and simply changes their direction. A Power Fractal can output both displacement and colour but be aware of the difference because they can look different and have different settings in the fractal.You probably want to give different seeds to each of the 3 fractals. If you don't, you'll just produce a displacement that goes along a diagonal vector, not much more interesting than what you have now.Matt

No, I'm lying! There was one attempt, but it was matte paint with NASA photos. But it quickly became clear that this was not the job I was dreaming about. Although with TG a satisfactory result is also not easy to get (if your apartment does not have a separate room for a supercomputer). In any case, it's good if it helps.

The render time I was able to reduce almost 10 times, and with this improve the quality of the picture (almost fully removed the fine noise). That I rendered 60 hours, now I can render for 8 hours on the same computer. So this is not the worst thing. You just need to leave the computer turned on for the night and the picture is ready in the morning.Much worse is how the settings are configured when the entire node network is connected and you need to see the result of a small adjustment of one parameter. As a result, you have to switch to an outlined node scheme or create test scenes and study the result after a few hours of rendering. Or you have to choose a small area (crop) and focus on it, but there is a possibility that the same parameter can have unpredictable influence on other sites that you have not looked at. Or it is simply good to know what and how it works and to foresee the result. The main thing for me now is precisely this.As for the quality of the render on the free version. Is it different from the paid version? Judging by what is listed on this page http://planetside.co.uk/terragen-product-comparison/, the free version contains the same render-engine as the paid versions, and the differences are only in separate functional blocks, which are usually required for solid professional work with integration with other applications.
Quote from: Oshyan on March 10, 2018, 03:24:40 pmAs long as you're using Defer Atmo, AA 6 should be enough to get low noise in most cases. At the least certainly if you use Max Samples (non-adaptive). Remember you can always increase the cloud quality, even if you can't increase AA. Also if you're using v3 cloud layers, take a look at the newer Voxel Scattering Quality setting in the GI in Clouds tab of the Render GI Settings node. You can increase that when you've hit a ceiling on quality from AA.- Oshyan
