I have an images as planes in my scene that I am adding on to. I lines up a plane with the floor in the image, and want to add assets to make it seem as if they are on the floor. The plane is blocking the object (as anything normally does) but I want objects behind it (and their shadows) to be visibleenter image description here

I want the car to go behind the plane and appear in front, so that it looks like it is on the ground in the picture. I also want it to have its shadow to add realism. Any way to do this?

I want it to act like the behind option that you have with reference images, where you can have it so that the object always appears in front of the reference image. However, I want the image to render as well so I do not have that option.

enter image description here

I want it to act like this, where the cube is behind the image but appears in front. (Excuse the randomness of the example, I am on a different computer.)

  • $\begingroup$ @Relevred i’m not sure, since I did not fully understand the layout of order. You said you wanted the car to “go behind the plane and appear in the front,” and I have little idea what that means. $\endgroup$

  • $\begingroup$ I want it so that its behind the picture, but appears in front with its shadow. I want this because I have a plane matching the ground and I want to be able to position objects on it so that it appears to be in the picture. I will add the blend file $\endgroup$

If you want to place the 3D car in a 2D image, you need to model some geometry.

Use the knife tool (K in Edit mode) on the background image that you have. Cut out the shapes of the pole/lantern, the tower, the wall, and the stairs. Cut it, then select the faces, duplicate them (Shift+(D) and separate them (P). Add a Soldify modifier and a Bevel modifier to the new object cut out.

For the tree, you only need half of the vertical outline. Then use the Screw modifier. While doing so, check the correct face orientation and origin.

Extrude the floor and correct the texture mapping in the UV editor if necessary. For the wall in any case. Add a Bump node to the stair's material. Set up a few lights.

Done. The car is now in the "image".

  • $\begingroup$ Great post, but this isn't relevant to my problem. I added more details because there seems to be some confusion $\endgroup$
