Hello all,
I was wondering how possible it is to simulate the way light behaves and casts in space 100% realistically in Unreal Engine 4, and if so, how it could be done.
Also, if anyone knows of an article or presentation that explains the differences between the behaviors of light in space and in an atmosphere, I would love to read it.
Thanks for the help.
That’s something I’ve wondered, I’m just not sure what the luminance value of the sun is in space, that’s pretty much all you need to know. I’m sure it depends on your distance but the only info I’ve found is based off values on earth.
I’ve actually begun this.
I started at first with just doing some research.
Then I figured the basic idea is to use the black body radiation function in the blueprint. The hard part was getting all the textures to work for an emissive material. However, once that was done, scaling became an issue (mostly because I didn’t know how big the map was capable of being.) Once you have all this done, you can place your stars, with the appropriate sizes, the various spectral types with proper temperatures (be sure you alter the emissive multiplier based on luminosity changes).
is what I had done a week ago. There are 309 stars in this footage. Please forgive the crappy screen capturing.
