Am I allowed to use multiple 3D models from the warehouse to decorate my webtoon background

Hello, I am drawing a webtoon and I was wondering if I could use models from the 3d warehouse to compose background scenery. For example, I would put some buildings and cars in the background and draw my characters in the foreground to blend in with the scenes. I’ve seen popular webtoons use 3d models in their scenes(like cars) and was wondering if they modified them or just used them straight out of the warehouse. Please let me know! Thank you :slight_smile:
