No picture yet. Important news: planets now load correctly and, above all, display correctly! They match the layout in the design tool 100%. It was difficult, but it worked.
What made it difficult? Assigning individual textures to each of roughly 60,000 triangles on a level-5 planet. To each one, taking account of orientation, drawing order, and the texture array layer. It may not sound very difficult, but it really is quite a task. And no, the textures cannot be applied in advance in the editor. This object is generated on the fly, with detail and access to each triangle. Each triangle belongs to a block, and the blocks contain different numbers of triangles.
