Trying to show what is behind a plane

[kenb0314]

I am trying to set up something...

I would like to have a plane with an image on it - say a forest.  And then have a solid object in front of it - say a solid wall.  If you render this you would see the object but not the forest.  Now, I would like to have a lot of small objects - say magic crystals floating in front of the wall...   BUT they would show the forest image from behind the wall.  And the tricky part, have the crystals not all show the forest in whole but only a small part of the forest - the part they are in front of.

Any thoughts on how to do this?   Thank you so much in advance!

just put the forest textures on some of your crystal object

I think that is my trouble, it always shows the entire forest, or all the crystals show the same version of the forest.  I was hoping to have each crystal only show the small part that they were in front of.   🙂

@rendermaster  very clever but somehow you will need to have the crystals reference a UVW Map that is the same as the wall's map and does not move as the crystals move.

you can put the forest as your environment map, no problem with it. then on the wall, right click on it and untick visible to reflection and refraction. in this case only the forest environment will catch on the crystal's reflection and refraction.

wall properties

then create 2 or 3 material for the crystal with a diffirent amount of reflections, and apply it to your crystals model

Thank you very much!
