I have spent the afternoon attempting to understand this programme. I have had a number of failures so I have I have experimented with creating astronomical objects.
I created a sun and an orbiting planet.
Progress was slow as the programme is complex with many options. Sometimes settings created seemingly random results. Camera angles are challenging because of the 3 dimensional nature of the programme.I have used the native textures in the programme.
The results are quite pleasing though and I would like to create more complex ones. I particularly keen to model a flyby of a planet or a solar system.
I need to research on methodology with Lynda.com or You tube videos.
