Strumpy Shader Editor [Now Open Source]

@Nick3d

You need to click on the master node in the graph and give the shader a name.
You can save the shader anywhere you want inside the asset folder.
Then when you open a material in the inspector you can find the shader in the dropdown menu.

 

Good grief, that looks awesome. Amazing work

 

waiting for it to be released. But no pressure just go at your speed!

 

I want to create a shader for breaking waves that will be seen from a top down view from quite a distance. Using a SinTime plugged into a Sin plugged into a UV_Pan I can get the texture to oscillate along the X but the amount is too much. Can I reduce the amount of movement in the X to create a gentle sway? Is it possible to have the texture move quickly in one direction then slowly in the other?

Thanks. Great tool by the way!

 

just multiply the sin result with something between 0 and 1

Oh wait i might be wrong :/

 

excellent work. i've been needing a decent shader editor

 

Hi Westmark, that works but its very slow now, can I speed up the cos time in any way?

 

@Eastereislandnick
try doing the same for that.
and use a range for multiplying so you can edit the value live

 

For getting arbitrary values for specular, emission, etc., i will usually use a multiply node with the first box for using my texture, and the second box will be using a "Float" node...

 

Woah this tool is amazing, i manage to create water shader with this tools even tough i have to edit the shader manualy after saving from the editor.


and Here's the shader.
View attachment $Refract.shader
btw is there somebody in here who manage to fix the refraction artifact that caused from the grab pass??

And here's the graph file. sorry for using 7zip on this, some how i can't upload .sgraph file. It says invalid file
View attachment $Water_Refl_Refr_Grab2.7z

 

not successful.
i had attached the shader.
if possible help me out.

 

well if iam not mistaken...

@Rahuxx

Remove these 3 lines:

Code (csharp):

1. Cull Back
2. ZWrite On
3. ZTest Less

and remove alpha from this line:

Code (csharp):

1. #pragma surface surf BlinnPhongEditor alpha vertex:vert

 

thanks

 

@Westmark

I tried it the shader i attached earlier and it worked, but when i tried in other few i did not find solution.
Please my master can you help?

 

03.shader still has a transparent tag and alpha in pragma

 

I updated my water shader, now it can use realtime reflection using script from http://www.unifycommunity.com/wiki/index.php?title=MirrorReflection2 for the reflection


Your shader editor is really awesome tool. Good job guys this editor is really cool

 

Hi. I have been following the tutorial. What a great program. I can really see the potential. The way the inputs and operators work, is really swish. If I understood the components of a shader better, this would be exactly how I would build an idea I have for a indie water shader. Does anyone know where there is an idiots guide to shaders? I would like to make a water shader that has the illusion of increasing colour intensity with distance from the camera (to create deep water), and also keep the surface effects of the island water (in the demo).

Cheers.

 

stramit, I've posted a detailed description of the shader that I would like to create, would you be willing to help?

 

You, good sir, have just blown my face off with the level of awesomeness.

 

I have a suggestion for enabling the free version to have a real time view if you are still looking into ideas on ways around the render to texture.

Perhaps it is possible to have the editor create a shader named temp(that is located in your extensions folder) that when you click "update shader", it compiles directly to this temp.shader file that will then be used by the preview window. Then when the user is done modifying the shader the export function could just save the shader again offering the option of where to save and what to name it. Basically just adding a dummy file to allow the user to not have to constantly work with the save and export dialog boxes. The one click and instant update would in essence just streamline the free users work around.

Just some ideas! Thanks again for such an awesome tool!

 

@Westmark

can you provide corrected shaders, as i am 0 in programing.

 

@ Maker - this is possible right now. If you look in the \Assets\Editor\ShaderEditor\Resources\Internal\Temp you'll see "TempShader.shader"
Apply this, and when you press Update, you'll see the updates in your scene.

 

Great

I'm making shader with ability to desaturate diffuse, i found reference code

And now I'm stuck. How to make "float gray = color.r * 0.3 + color.g * 0.59 + color.b *0.11" with nodes?

 

Thank you. )))
Now it works.

 

YAY! And if i may be so daft, what is in version 3?

 

Hello Stramit,

any update is planned for this great tool?

Kenshin

 

He already said 3.0 will be out during Unite.

 

Oops... my fault, sorry!

 

Yes, however, this does not allow the viewing of the shader in the creation window. I was suggesting a way to get the shader to be viewable in the real time viewer since the real time view also requires a quick compile with the need to press "update" to show the changes. Until then, I will use this method to view shaders in the scene view to test my work.

 

@Maker - As far as I know, you'll always have to update the shader to get it to show changes, no matter the method. Changes have to be compiled before the engine can display them. Unless I'm misunderstanding your point.

 

Snow sparkles shader



Is View Direction node changes when camera moving in scene, not rotating?

How to get pixel's direction(camera vector + reflection vector) in world coordinates?

 

Would it be possible to create a matte shadow shader for Unity3 with the shader editor?
Just like this one here (= Unity2.x version) : http://forum.unity3d.com/threads/14438-Matte-Shadow?highlight=matte+shadow

 

Speaking of shader bugs, Gloss and Spec seem to be reversed.

 

Sorry for injecting the thread, I tried to make such shader (it works for me, at least) - hope this helps. http://forum.unity3d.com/threads/64...actual-object.?p=422023&viewfull=1#post422023

 

Just wanted to say thanks for this sweet tool. Its made shader life a hell of a lot more bearable!

Should we build up a spot on the wiki or something to build up a community library of sgraphs?

 

@dave: sounds like a great idea

 

Wow.
I'm simply amazed.
This is what I always missed in Unity compared to the Unreal Engine.

Thanks. Really.
