About CC license

I’m interested to know how to manage the CC-by license when there are more than 10 models are used to create a 3d scene using models under CC-By license to generate a commercial picture ?
it would be strange if i take the 1/4 of the picture size to type 10 lines to give credits to all_
is good to give credit to author, but also it must be appropriate and one must have an appropriate choices and places for mentioning the original author
