I used the hints from <https://www.youtube.com/watch?v=tpTzwyiGByE> in using the PBS. It is assumed that there is a separate folder, named “PBR_Tutorial”, in the Project section (under Assets) where the sample scene is to be created and stored. If the folder does not exist, you can create one (or store subsequent items in your folder). text/html 2024-08-26T20:29:12+00:00 Anonymous (anonymous@undisclosed.example.com) https://mail.stemin3d.net/tech/tutorials/nightsky?rev=1724704152&do=diff Simulating the Celestial Sphere in Blender Nightsky view can be simulated using real photos such as the ones from NASA's Scientific Visual Studio (Deep Star Maps). You can download various nightsky photos (Equatorial or Galactic) and other relevant maps (constellation figures, constellation boundaries, or coordinate grid). You can use these images in texture mapping to the Blender World to simulate the celestial sphere. This page describes how to create such a world from scratch, and the nights… text/html 2025-12-08T19:40:58+00:00 Anonymous (anonymous@undisclosed.example.com) https://mail.stemin3d.net/tech/tutorials/orbit_calculation?rev=1765222858&do=diff Calculating orbiting body's position at a given time T orbital_elements kepler_orbit orbit Creating an orbit for a planet and place the planet on it To create a planetary orbit and place a planet on it so that one can calculate precise position of the planet at a given time can be done by using $a$$a$$P$$e$$i$$\Omega$$i$$\Omega$$\omega$$\nu$$T$$T=0$$(a_0,e_0,i_0,\Omega_0,\omega_0,\nu_0)$$T+\delta T$$\nu$$T=T+\delta T \equiv new$$(a_0,e_0,i_0,\Omega_0,\omega_0,\nu_{new})$$\nu_{new}=\nu_0 + \de… text/html 2024-08-26T16:35:43+00:00 Anonymous (anonymous@undisclosed.example.com) https://mail.stemin3d.net/tech/tutorials/sunearthmoon?rev=1724690143&do=diff Procedural (Script-based) Sun-Earth-Moon Model Creation Click here to see detailed step-by-step procedure to create a Sun-Earth-Moon model Remember that in Unity, the Y-axis is chosen to be the vertical axis unlike the astronomical convention, Blender, and even Unreal Engine. text/html 2024-12-02T17:28:44+00:00 Anonymous (anonymous@undisclosed.example.com) https://mail.stemin3d.net/tech/tutorials/unity?rev=1733160524&do=diff Share project with others * For you: * Right-click your project folder in Project view > Export package > Export (make sure everything is selected) > Choose a place > Send him the package * Someone: * Create new project > File > Open Scene > Double clicks it text/html 2024-08-26T14:37:31+00:00 Anonymous (anonymous@undisclosed.example.com) https://mail.stemin3d.net/tech/tutorials/unreal?rev=1724683051&do=diff Space scene in Unreal Engine 5.x * Various tutorials for UE5 (asteroid belt, Solar System, Nebular, Neutron Stars, Blackhole, etc.): <https://www.youtube.com/playlist?list=PL3h9_2VztKEFm-WauCP9n_m3fNBqRruAR> * Step-by-step tutorial for creating Solar System in UE5: <https://www.youtube.com/playlist?list=PL6jMdZzbgqlCumwccHDRHyW_5m6fOluom> * Create User Interface in UE5: <https://www.youtube.com/watch?v=kM27HYbpvc0>
