I have a scene with some objects in it and wish to add a background of a tiled image to add interest, replacing the sky color with a tiled image.  Is this possible in blender?  I'm rendering using 'CYCLES'.   I tried to go to World -> Surface -> Color:  Image Texture and it does nothing but turn the background off-white.   I tried putting a giant cube around my scene, then adding an Image Texture node but no luck.  Help anyone?  :-)  I'm attaching a screen shot FWIW.  Thanks!

While in the node editor click on add and their is a background node you can add but it might not show up in 2.70 I know in 2.71 I had to click add and scroll down to search "background" and enter and it adds the background node. I still a novice with cycles myself but that was the quickest answer I could find at the moment if that does not help I am confident another of our forum members will chime in if they have a better answer.

 

Good Luck

Thanks.  I already have a Background node with an Image Texture feeding into it.  I'm attaching the World view from the Node Editor to show what I mean.  It ain't working!  Grrr

Found a solution:  use the "Environment Texture" node instead of "Image Texture" per [ http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/World ](http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/World)

However, this does NOT tile the image.  Anyone know how I can tile the image acroos the background instead of having a huge image?

enviroment tex is "usualy" an hdr (dosnt have to be ) so wouldn't really be tilable

could try adding a mapping node then scale it from there , never tried that so not 100% it would work

or could load a plane and add your tile to that just have to get scales/angles right for cam view

Input>Texture Coordinate (Generated, Window, or Camera) plugged into Vector>Mapping, which is then plugged into the vector socket on your image texture. X and Y scaling settings should do the job. Other adjustments of interest are Z-rotation and X and Y location.

Sounds excellent, I'll try that too.  What is working very well in my case now was to create a hexahedron (anisotropically scaled cube) around my scene and texture an image onto it.  Gives exactly the effect I want for my project.

Hello wealthychef,

 

try this (in Blender 2.71): World -> Surface: Background, Color: Environment Texture

I took a landscape from cgtextures.com in the example (which is unfortunately not tiled so what you see depends on the view angle).

Note: the background is only visible in rendered preview!
