I’m working through Blender 2.5 Lighting and Rendering by Aaron Powell. I’ve reached Chapter 7 on Materials but have struck a snag. Trying to use Material nodes for glass material for a bottle I’m getting the error message No render output node in scene when I try to render.
The material consisted of a single material node with some transparency settings, and an output node. The preview showed fine (in the Materials panel). However nothing I did could get it to render without this error. I deleted the material and assigned a simple default non-node material to the bottle but I still get the ‘no render output node in scene’ error despite that no object is using node materials.
So, now I’ve hit the real bottle, can’t progress with the book, and am wondering if I need to install the 32 bit version of Blender (using Win Vista x64 with 64-bit Blender 2.55)
Sounds like your compositor is enabled, and that there isn’t an “output” node in your compositor window. Have you checked for that possibility? (The fastest way to check is to uncheck “Compositor” in your render panel and see if the error goes away.)
Thanks, I found that Compositing and Sequencer were checked under PostProcessing in the Scene panel - I’m guessing that what you were referring to. I haven’t used 2.5 before so the new interface is confusing me. Works now. Many thanks.
benu is right, but I wanted to clarify a little because I had the same problem. When you open the node editing window there are three buttons under it. The familiar material sphere, the texture checkerboard and a compositing button. Push the compositing button to get that window and see if you have an output node there. I had deleted mine. You need a render layers input node and a composite output node in that window. This is also why I couldn’t see my appended group, because I wasn’t in the materials button window.
