Making an Object Receive No Shadows

Support Materials and Textures
1

Hello all, I have a problem which I just can’t seem to get around though I have checked many forums and sites to find a solution. I am using Blender 2.77, cycles. I imported an image as a plane which is meant to be an outside scene viewed through a window. (I am following the “Intro to Blender 3D, Environment” tutorial series) However, I can’t find a way to make the object not receive or cast shadows and not be reflective.

I tried using the Light Path node with a math node set to maximum as was suggested by several other members in other forums (I must be doing something wrong but I none of others I saw made a material setup for an object with an image) and this is what I have:

Here it can be seen that the image plane is receiving shadows. It is very dark compared to the source image in the UV image editor on the left:

If some kind person could please help me and tell me what I’m doing wrong I’d be really really really grateful. This thing has been getting quite annoying!

Thanks in advance!

go to object panel bottom cycles
and remove shadow

happy cl

don’t use a diffuse shader. if it’s environment it will cast light itself! so just plug the image into an emission shader (strenght=1) and don’t mess with lightpath

Thanks very much, Isscpp. Using an emission shader worked perfectly! At last I can get on with the project now! :slight_smile:
I your instructions first, RickyBlender, but that didn’t work. Once I put a light in my scene the image plane still received shadows. Turning off shadows in the object data panel must just stop it from casting shadows? Anyway, thanks again for the help.

I tried the Emission Shader idea and it worked really well. In my case, I had to turn the strength down because it was too bright. This is very useful though as it means you can adjust the image to fit in better with the rest of your scene.

so so thanks to you and Animations07.
