Some serious reasons why this model is nothing special, doesn't keep standards and you can create it FOR FREE: The texture which has beeen used was published on this site https://www.solarsystemscope.com/textures/ (free Download). He did not even optimize or change anything, he just used the free texture and called it "Sun_color_emission", which is not an emission map, it is the base color map. There is no emission map included, which should have been added if this would have been done seriously. Nevertheless, he included a normal map, but it is kind of "useless", because fire on the surface of the sun won't even have shadows or a light source other than its own. last point regarding textures: Maps like Metallic, Roughness, AO are not in the package, although he tells in the description that these would be included. The Sphere is just a simple sphere. You won't get any "fire-like" mesh surface. The biggest downside ist: the mesh has around 25.000 Vertices (results in 50.000 Triangles), and that is not enough: the mesh is made of a subdivided cube, it isn't even a typical sphere. This model could have been easily done with a real sphere, and with maximum 1.500 Vertices (or 3.000 Triangles). At last, the UV is totally broken (as I could see in Blender) - it is overlapping the image. Unbeliavable! Conclusion: this model can be done in a few minutes with free software and free textures, and even better. The publisher even doesn't know the difference between base color / diffuse map and an emission map, and isn't able to deliver an optimized mesh. He did not polish the product at all, which is higly unprofessional. Any price over 2$ is too much. Don't buy it in case you are able to create a low-poly sphere with the freely available sun texture. Thank you for reading.
