Please place a vertical scroll bar on the “Scene Collection” tab, and Please also Render floor shadow transparent in the “Viewport Render Animation” Eevee / LookDev.
The scrollbar appears when there are enough items that it is needed.
The Viewport Render is quite basic and just renders what is shown in the viewport. If you want more control, you can set the render engine to Workbench and change the Film settings to render with transparency.
Thanks for the attention, but do not stay the same eevee, effects of light and shadow. Do you have any other ideas?
