Shadow has to stay within the picture

Hello everyone!

Recently we’ve bought Solidworks Visualize Standard and are new to the software.

I want to render different products with a white background and shadows on the ground in Solidworks Visualize Standard. The backplate is completely white and I’ve tried different environments. Everytime I get the same results: the shadows are " cut off " on the edges of the image.

Is there a way to get rid of the sharp " cut off "?

Thanks in advance!
