I rarely ask questions here, but when I do, it uses to be tricky
I’ve never managed to find any good way to previsualize a node output in the node shader tree. In the compositing, it’s very easy with Viewer Output and Backdrop, but what about shader nodes ?
Let’s say I want to visualize a Noise Texture Node output.
Usually, the only solution for me is to temporary output the node on a plane with a Emission Shader, like so :
But today I’m stuck, because I’m working in the Shader Node Tree of a Spot Lamp.
I’m working on masking a spot light, like so :
On the image above I’m using a PNG texture, but let’s say I want to do it fully procedural with some noise textures, etc… How to previsualize the noise texture ? Because here is the tricky part : we are not dealing with a Material .
It’s only related to Spot Object Data. As you can see, even if I’m in the Node Tree Window, there is no Material name.
It means this Tree is not usable on any temporary “Plane” for visualisation. It’s only Spot Light Data related.
Any Idea how to resolve this ?
