hi guys, I'm a newbie in blender and I just want to ask how to map and image/graffiti in surfaces that already has texture in it where there is X MARK (see image attached)I have my node setup also attached. I tried the uv maps(below the vertex group) but I dont know how it works,I also tried overlaying using mixRGB node but it maps to every surface that has concrete.I cant control it

  • $\begingroup$ @Allen 127mb is not a problem at all! Be sure to pack your images. $\endgroup$ Feb 15 '15 at 15:31

A mix RGB node will work fine:

Use the alpha from the image on top for the fac input. You may need to try reversing which image is on top for best results.

  • $\begingroup$ 4shared.com/rar/mBOMonCdce/test.html here i have a test version, i used the color and the alpha and it seem working because i have one side with one circles .but the other side has circles map into them as well $\endgroup$

  • $\begingroup$ another thing this is that. when i scale the side with one circle i ended up scaling the cobblestone texture too, instead of just scaling the circle $\endgroup$

  • $\begingroup$ @Allen You need to have different mapping nodes for each of them. $\endgroup$ Feb 15 '15 at 15:51
