Why does my render output change everytime I click render image? I am using Blender v2.83.0 to render a Motion Tracked car with Smoke simulation in Blender and I cannot seem to get my render settings correct.

I am getting a problem where every time I click 'render image' I get one of four options. I either get the full scene rendered correctly, just the car, just the car but it's blacked out or the full scene rendered correctly but the smoke is stretched. Image examples can be seen below:









All my layers are on the same view layer and I would really appreciate any suggestions. My compositing is simply a render layer into composite.

Thanks in advance,
Ethan
Physics must be baked before rendering.

Go to Phisics settings, find Cache tab, change type to Final and press Bake All button.



Also notice, blend-file must be saved on disc.
