Light Issue
I just started using Twilight and for the life of me I can't figure out how to get the images I want. I build Star Trek ships in Sketchup and I just want a simple clean render with a black background and omnidirectional ambient lighting. I wan the item evenly lit from every direction. Is this something Twilight can do?

Learning a new software can be frustrating. Please have patience while you learn the ropes.
Please watch the getting started video tutorial series linked in my signature.
Open Edit Environment dialog and from Presets (bottom right little button) choose "Ambient".

Re: Light Issue
If you want background black, but light from all around you will have to render a mask and place the object on a black background. Render with lighting shown in post above.JAFisher44 wrote: ↑Tue Jul 13, 2021 3:42 am with a black background and omnidirectional ambient lighting.

Re: Light Issue
Use "Background Color" and choose pure black.
Build a cube around your object. Apply an emitter material to that cube and reverse the faces so that the faces aim towards the inside of the cube. Put that cube around your spaceship.
Set the emitter material type to "invisible".
Now you have black sky and ambient light from all around your object.
You can also use "background fit image", use a starry night sky background or whatever image you like. Set your rendered image size to match the aspect ratio of the sky image. (seems to work best with .jpg images for some reason as opposed to png)
Best is to create a starry sky spherical sky, or find one online, then use that in spherical sky slot. you can still use the ambient light box described above and shown in attached .skp scene.
Attached scene as example.
