I am new to using blender and have been watching youtube videos on how to use it. I copied the steps of how to create cracks in a surface. I can see what it looks like if it gets rendered but then when I go to render it I get the message "no render output node in scene". It's not an animation, it's just a single image. Here is a screenshot of all my nodes and the error after trying to get it to render.
The issue is most likely that you removed the composite node accidentally in the composite node tree.
Select the composite node tree button (highlighted left).
At this point, we should take a step back, and make sure that what I think is happening, is happening.
There are two signs that I'm wrong:
- Use Nodes isn't enabled
- There is a composite node
If both of those aren't true, then continue.
Now there are two ways you could solve this.
#1You could disable Use Nodes. When this is disabled, anything in the compositing node tree is ignored.
#2Or you could add in a composite node, and attach it to the Render Layers node.
ShiftA output -> composite.
And then attaching the render layers node to it.
