So i was modeling something, i was near the end but then theres the issue when i was rendering.
its getting malformed despite what i see in the viewport…
Im not sure if its physics or what but whatever it is, how can i fix that? -DenneD
You seems to have added a Subdivision Surface modifier which does only show in the render (disabled in view)… ?? Also you lights are… “queationable”… 
seems like you were correct on the subdivision, i forgot it was there even. Which is odd cause it was set to be viewed in real-time, idk.
Lighting? yeah too much “sun” does that lol
