► Texture Adjustments ◄

Yes, I use the same material
I have to use different material if I would like different value ?

 

Yes, of course.

So what is the method to do it ?
I have a prefab, in which I want to change his color through the shader. And these instantied gameobjects will be destroyed ~10s later. So I dont want to save the created material.

Code (CSharp):

1. obj.renderer.material = new Material (Shader.Find(" shader_name"));

Is this method fine ?

 

It's fine. Do not forget to destroy material after using.

Ok, Thank you !

 

Hey, trying to write a scaled screenshot using this asset and the result always comes out as a blank gray PNG:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using VacuumShaders.TextureAdjustments;
4. using System.IO;
5.  
6. public class ScreenCapture : MonoBehaviour {
7.     public Camera cameraToCapture;
8.  
9.     public void SaveScreenshot(){
10.         StartCoroutine(SaveScreenshotRenderToTex());
11.     }
12.  
13.     IEnumerator SaveScreenshotRenderToTex() {
14.         //Wait for graphics to render
15.         yield return new WaitForEndOfFrame();
16.  
17.         RenderTexture rt = new RenderTexture(Screen.width, Screen.height, 24);    
18.         Texture2D screenShot = new Texture2D(Screen.width, Screen.height, TextureFormat.RGB24, false);
19.  
20.         cameraToCapture.targetTexture = rt;
21.         cameraToCapture.Render();
22.         cameraToCapture.targetTexture = null;
23.  
24.         RenderTexture.active = rt;    
25.         screenShot.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);
26.         RenderTexture.active = null; //Added to avoid errors
27.         Destroy(rt);
28.  
29.         //Split the process up
30.         yield return 0;
31.  
32.         // 1. works - original image comes out fine
33.         byte[] bytes = screenShot.EncodeToPNG();
34.  
35.         // 2. doesn't work - scaled image produces a blank gray file
36.         /*var h = (int)256;
37.         int w = (int)(Screen.width * 256f / Screen.height);
38.         Texture2D scaledShot = new Texture2D(w, h, TextureFormat.RGB24, false);
39.         Adjust.CopyAndScale (ref screenShot, ref scaledShot, w,h, false);
40.         byte[] bytes = scaledShot.EncodeToPNG();*/
41.  
42.         File.WriteAllBytes(Application.persistentDataPath + "/capture.png", bytes);
43.     }
44.  
45.     void Update(){
46.         if (Input.GetKeyDown (KeyCode.C)) {
47.             Debug.Log ("saving screenshot to "+Application.persistentDataPath);
48.             SaveScreenshot ();
49.         }
50.     }
51. }
52.  

 

RenderTexture.active = rt;
screenShot.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);
RenderTexture.active = null; //Added to avoid errors

Add: screenShot.Apply();

Hello,
CopyAndScale works well. But I have to resize textures more than Max Texture Size allowed GPU. How can I do that using Texture Adjustments

 

You can't, if GPU does not allow.

hey man)
i bought asset.
and there have no selective color for hue saturation

 

It will be available in the next update.



VacuumShaders - Facebook Twitter YouTube

 

Any release date for next update (w/ selective hue/saturation color)?
I'm waiting for it to buy this interesting package.

 

It's planed for April, 2016.



VacuumShaders - Facebook Twitter YouTube

 

Great! Thanks

 

Finlay have time to continue working on v2.0





VacuumShaders - Facebook Twitter YouTube

 

Some info about Texture Adjustments v2.0:

• New redesigned fastest API

​

• New API is completely oriented on textures and is not compatible with previous one.
• Per-mesh adjustment shaders will not be supported and are removed. Save them if you need.
• Package category will be changed to Editor Extensions.
• New adjustments (and even more to come)
• Adjustments can be added/removed arbitrary and reordered.

​

• Most adjustments will have custom mask options.
• Most wanted batch converter.

​

• Saving textures to png, jpg and new Encode To TGA

​

Releasing in May, 2016.

Just finished working on v2.0.
Need one more week for preparing package for the asset store (documentation, example scenes, video tutorials, ...).
Those who can not wait more just send purchase invoice to vacuumshaders@gmail.com and get early access.

Trying to see if this will do what I need it to do. After saving the texture, will I be able to use that texture on any model? Will I be able to change the shader after saving the changes?

Thanks. Looks very nice.

 

v2.0 is very optimized and works extremely fast with RenderTextures and Texture2D files.
Adjusted textures can be used on any model and shader without problem.
Tool also can be used as Image effects processor in run-time. It is so fast.

Error...
When I use "Color Replace".I get this error and a sweet black screen
PNG Texture which I used and my unity is Unity 5.3.4f1

 

It looks like the error is coming from Unity's Editor GUI having a corrupted stack.
Does it happen only with ReplaceColor or with other adjustments too?
When did it happen? After adding adjustment or during parameters changing?

Hello,

This version 2 looks awesome and we can tell you put a LOT of work on it! Congrats
I've just bought it!

Quick questions:
- Do you have an API to load a file from disk? I currently use File.ReadAllBytes but maybe there's something faster?
- Also, do you have an API to read width/height from a file on disk?

I know those are not really Texture manipulations, but hey, maybe you did them anyway?

 

Also, do you plan on adding a rotate API? That would be nice... At least rotate 90°?

 

I have no API for working with image files outside Unity.

Good idea.

Just submitted update v2.1
• Added new adjustment Transform/Rotate.
• Shader keywords used by plugin reduced on 75% (from 97 to 24).
(Delete project Library folder after updating for releasing unused keywords).

Works like a charm! Thanks a lot
Just a small question, why did you limit it to 0, 90, 180 and 270°? Why can't we specify the angle we want (something like 37° for example)?

 

It is difficult to define what user wants from rotating image on 37°




VacuumShaders - Facebook Twitter YouTube

 

Rotating textures is nice when you are trying to fit a wood texture to roof trim or to a cross bar.

 

Well yes, you're totally right, but maybe the best (and default) thing to do is what you did on the bottom left, having a transparent background when it's rotated?
Transparent or white on the bottom works for me at least
Maybe you can add that first, and implement the other things you did on the screenshots then (when you have time)?

 

So this is the rotation you are asking. With customizable background and wrap mode?
I'll try when have time for it.

Seems more than perfect! Looks awesome.
Does it handle the fact that you maybe first render your texture in a 1280x720 rectangle for example, and when you rotate the texture, the texture stays in this 1280x720 rectangle?

 

Well of course no problem, just wanted to give a "hint" of a feature that could be nice.

 

Hello again!

Just to drop a feature request. It would be nice to have a crop feature, to not resize, but crop from a texture to another, by specifying the desired width/height and crop method (left, right, top, bottom or center)

 

Is there an example for how to use the new API that's not in video format? It would be a lot easier to google for stuff if you wrote it instead

 

@Arkhivrag Does this plugin work for a texture of type Sprite (2D and UI) with sprite mode set to Multiple?
I have multiple sprites in a spritesheet and I would like to change a specific color, expecting all sprites to be affected automatically.

 

Add to wishlist.

Example scripts are included.

Sprite is just a texture file yes (.png, .tga, ...)? so plugin will work.

Hi, I just buyed your asset for a delivery i have these hours (...) actually I need to contrast a texture, coming from a camera.
It's working really fine in editor, but as build it doesn't work, from debug I saw that is missing shaders in path Hidden/....,
I'm currently using Unity 5.4.f3 pro, and gtx 1080, how can i have this working in a build ?

Thank you

 

Add all used TextureAdjustment shaders into Always Included Shaders array, in Graphics Settings window.

version 2.21
How to scale texture2d smoothly? TextureResizePro.ResizePro is not smooth, is there a scale mode can be set? such as:Linear etc

 

It includes ResizePro plugin (example here). There is only one scale mode (name is not defined).

The quality is excellent!
It is GPU accelerated and interpolation algorithm name is irrelevant.




VacuumShaders - Facebook Twitter YouTube

 

If using editor there are no unused files. If only run-time API then Shaders folder can be deleted.

This asset looks pretty great! I'm looking for something quite similar but also with support for multiple images to be used and blend modes to be applied between combinations of Hue Saturation and Luminosity nodes. Also I need this to work on mobiles (So not using RenderTextureFormat.ARGBFloat / TextureFormat.RGBAFloat). Would this package be suitable for what I'm after / could it be?

 

Two textures can be blend with built-in 18 blend modes. Additionally can be used Mask texture options.


As for RenderTextureFormat, default settings are used.
If SystemInfo.SupportsRenderTextureFormat returns true, plugin should work.
