Bug Gradient resetting almost everytime I try to do something in my ShaderGraph

I sample from two gradients, one for alpha and one for color, and the gradient goes back to solid white every time I switch back to the window, so everytime I want to save the Shadergraph, I need to manually set the two gradients to the correct gradient preset again. It is quite annoying...

 

This happens to me as well once in a while. Gradient nodes are wiped (all white or all black). Restarting Unity, Re-opening Shadergraph etc. works fine - I don't know when it happens but I will keep an eye on it.

 

@Shaunyowns
It happens to me too.
Most of the time I noticed, when using undo (ctrl+z). Btw. undo is very slow shader graph.
There were some probably other cases, but unable to recall them. Or maybe were indeed ctrl+z..
Issue is present 9.0 preview 55. Uncertain if it was as well 8.2, but I think it was too.
Using Unity 2020.3.1f1. But also was issue present in 2020.2.

I lost gradient property multiple times, in different shaders. Had to set colors again.
Sometimes is hard to notice, when focusing on different part of the graph (zoomed).

I am not sure, if that may even apply to cross multiple open Shaders, but haven't tested. Had some impression. Just need keep an eye on it.

For now, I add note above each gradient node and create templates in HDR Gardient Editor. Is a bit annoying but works for time being.

To replicate

• Create New shader graph in my case Unlit Shader Graph

• Create some nodes

• Populate Gradient with anything

• Add some more nodes. (You can skip this step).
• Save shader
• Close shader
• Reopen Shader
• Add one more node.
• Ctr+Z few times.
• Now Gradient should become white.

In my case, I can replicate it every time.

 

@Shaunyowns I do wonder, was this issue addressed and replicated?

 

I'm still experiencing it, with Unity 2020.1.6f1. Undoing while in shader graph resets the gradients to blank white.

 

Anyone who comes upon this in the future, i was running into this issue on 2020.1.7, my gradient node in shader graph was never being saved and i had to reload the shadergraph everytime for it to appear in the editor. the more pressing problem though was no matter what i tried the gradient would never show up in the build either.

Luckily, I updated to 2021.1.6 and this issue was fixed

 

Submitted a bug for 2020.3.8f1 where I'm still experiencing this.

 

In 2021.1.1f, it still happens

 

Happens to me too every time I boot up Unity

 

Actually I found a fix (I think). If you put a gradient as a variable and then assign your gradient (rather than using the gradient node), it won't reset for me like it used to. Notice on the upper righthand side I added a new gradient variable and replaced the gradient node with it. If this doesn't work out for you, I would write a quick script that references the gradient variable (using SetColor("Gradient_bb19e34b3d14465a9013cbae3c6339cc") in my case) and set it to whatever gradient you want in a Start function.

 

Can they not reproduce from my post above?
#4

Btw. I tried now:
Unity 2021.1.6f1
Shader Sraph 11.0.0
And HDR scene, with lit graph.
I can not reproduce bug anymore.
Maybe is fixed?

 

@Antypodish are you using git?
@LandonTownsend I cannot reliably reproduce it in a new project either. But, it is randomly occurring consistently in my current project. I don't know why or when it will happen, but at a certain point, opening the shadergraph on my complex shader with gradient will show white gradients. However, something to note is that the actual values in the gradients that are not properties are correct in all materials that use that shader. As long as you don't save it when it occurs, the materials that use that shader will still have the correct gradients (again even though the gradient isn't exposed).
@Twilight_18 Trying out your fix. Isn't it annoying AF we can't expose gradients? I

 

Yes. Why asking? Is that relevant to subject?

 

It might be - I think I have narrowed down the guaranteed reset to switching branches. But I am so friggin' busy I don't have the time to wrestle with the actual work on my project and restoring lost gradients after testing git actions.

 

@LandonTownsend Try converting a few nodes with a gradient into a subgraph. Repro 100% in 2020.3.16f1

 

Having a similar issue on 2022.1.0b4
I know 2022 is in beta, but seems like the exact same problem. When using Gradient node (instead of just Sample Gradient with attached gradient), the Gradient node resets. I couldn't figure it out exactly when, but felt like it happened when updating the Plastic SCM branch. Or at some other points when recompiling the shader (like just saving the graph).
I'll test using the Gradient as variables as a workaround.

 

I'm also having this problem, I had it in 2019,2020 and 2021.1.25f1, its pretty annoying

 

This bug is still going strong in 2022.1.15f1. Very annoying.

 

Absolutely the same problem on 2021.2.11f1

 

same in the last version 2021.3.16f1

 

Unity version 2021.3.23f1, the problem still exists.
