One image for all objects

Question

I created a wall with over 100 bricks. I want a logo on the wall. So some bricks will need a part of the logo. What's the fastest way?

Hello :). What have you tried so far? Perhaps projected UV would work well. — jachym michal, Sep 20 '20 at 13:28
yes, select all the cubes, choose a frontal view, go in Edit mode, unwrap with Project From View, move the faces in the UV Editor so that the Logo appears where you want it to appear — moonboots, Sep 20 '20 at 14:14
Does this answer your question? How to add image texture to an existing material? — lemon, Sep 20 '20 at 16:25

You can get there with UV projection.

Select all bricks and switch to Edit Mode
Get in front view (View > Viewpoint > Front)
Select all vertices and go UV > Project from view
Rearrange your UV map

Useful hack:
• Use a BW logo with black background
• Set the image to clip (so it doesn't repeat)
• Use MixRGB node to control the colors inside Blender

I think the point (certainly from the tags) is that the wall is made up of multiple bricks - not all one mesh - so that it can be run through a rigid body simulation. However, your solution does work just fine, providing you select all the separate bricks prior to the UV unwrap project from view. – Rich Sedman Sep 21 '20 at 14:38
@RichSedman You're right :). I forgot to separate the array when making the gifs. But it works the same way for 60 individual bricks :). – jachym michal Sep 21 '20 at 14:44
Updated the gif now, thanks again :). – jachym michal Sep 21 '20 at 14:55

You can also do it with an empty as the Object of the Texture Coordinate:

Give all your objects the same material.
Create an empty in front of your cubes.
Create a node setup with Texture Coordinate (Object output socket) > Mapping > Image Texture (Clip mode) > MixRGB > Diffuse > Material Output.
Plug the Image Texture Alpha output into the factor of the MixRGB.
In the Texture Coordinate, choose the empty as Object.
Move and rotate the empty to place the image correctly on the faces.
Give the other faces of your cubes another material if you don't want the image to be stretched.
