Question Multiply node previewing as a square? And shader not saving?

Hi everyone,
i just had my first look at the Shader Graph and ran into problems. To get a feel for it, i was trying to create very simple shaders for learning purposes. According to images / videos i saw online, when connecting for example the multiply node to an effect, like fresnel, then the preview in the multiply node should also be this "material-sphere". For me it's just a black box. Or rather a very zoomed in square preview, since i can see some changes when adjusting the fresnel effect to extreme levels.



As you can see in the main preview the changes still get applied to the master. I'd just like the multiply node to show a similar preview to the fresnel effect or main preview, which is what i saw in videos. As it is now it kind of feels absolutely useless and i'm not sure what i'm doing wrong.

Also; is there a save button i'm missing? Because even after pressing ctrl+s, when i close Unity and start it again the shader graph is back to being empty.

More-or-less-solved Edit: While ctrl+s did not work, saving with the hard to spot button at the top left of the window works.
As for the multiply preview, in some videos, like below, it's shown as the material preview, while in others it's just a square.
If anybody knows why it's sometimes a square and sometimes the material preview, i'd still love to know that. I believe i'm doing pretty much the same here. Was it changed in a recent version? I believe the material preview was way nicer if that's the case:

 

I'm using the 2019.1.8f1 version, which is where the problem occured. I originally worked on an older project (but with the 2019.1.8f1 editor) which is where the above problem occured. I then created a new project with the LWRP preset and it worked better, even tho it was still a 2D-representation on the multiply node. If i remember correctly tho, i believe it was at least not fully black using the same shader graph.

 

Trying to learn some Unity Shader creation after working with Unreal for awhile. I am using 2019.2.11 and this issue of no preview that Yoreki mentioned is still occurring which is getting frustrating. It appears we were working on the same tutorial.

 

Any news on this issue? I'm facing the same problem as well...

 

I have a Custom Function node, ported it to a subgraph where all node previews are 2d, however when I use the subgraph as a node, it shows the preview as a sphere. Is there any way I change that to show a 2d preview?

I'm on the latest ShaderGraph package and latest Unity 2019.3.0f3

 

You can change it in Editor>Data>Nodes>Utility>SubGraphNode (In the shadergraph package folder) on line 153 as a workaround for now if you really need it.

 

How to change it? I really want to know!!

 

We really need this option to be editable. Please add a checkbox to choose what to see. It is very difficult to preview subgraphs on spheres. alexanderameye thank you for temporal (I hope it is temporal) workaround

 

The workaround doesn't seem to work anymore for me on Unity 2020.1. Not having a 2D preview on my graphs really makes working with them hard for some of my shaders. I hope this toggle gets added soon

 

Another vote for being able to choose a 2d preview for subgraphs, or at least providing it as an option on the preview node! Especially when you start nesting subgraphs, I'm basically unable to see what I'm doing at anything except the lowest level.

 

Dang , that was something That I'd love to have , it would make it much easier to be able to have a custom mesh on some of that nodes to test things like vertex color and such...

 

To everybody waiting for this like I am
