Hi, everybody :) I joined this forum because I'm currently writing a sci-fi story and I want to create an alien world that is scientifically correct, but due to my lack of knowledge and experience I'm facing some big troubles. I have a ton of questions(I hope I won't bother you much). So here is short description of my plot: there is an icy moon orbiting around a gas giant around 20% bigger than neptune. The moon itself is almost the size of the earth has almost the same atmosphere as earth, and these bodies are all part of a P-Type binary star system with one big yellow dwarf(like our sun) and the second star is orange dwarf 16% smaller than the main star, both stars are around 0.2AU from each other. The gas giant is 2.5AU far away from the both stars. I suppose all objects on the icy moon would cast two shadows, but I have no Idea how exactly they should look like during the different times of the day(sunset, noon...) would they be fuzzy on the dawn and sharp clear at afternoon? Please give me as detailed description as possible, I tried to render a scene on Maya with two lights and one solid object, but I can't make good render output because I'm touching maya for the very first time... Thank you in advance.
