 ## 25 - 🟩➜▢ Green Screen to Transparency

 **Description:**  
 Transform greenscreen into transparency.  
 Need clean greenscreen ofc. (Can adjust threshold but very basic node.)
 
 ## 26 - 🎲 Random line from input

 **Description:**  
 Take a random line from an input text. (When using multiple "Write Text" nodes is annoying for example, you can use that and just copy/paste a list from outside.)
 
 ## 27 - ♻ Loop (All Lines from input)

 **Description:**  
 Iterate over all lines from an input text. (Good for testing multiple lines of text.)

+## 28 - 🔢 Text with random Seed
+
+**Description:**  
+
+❗ This node is used to generate a random seed, along with text.  
+But what does that mean ???  
+When you use a loop, the loop will use the same seed for each iteration. (That is the point, it will keep the same seed to compare results.)  
+Simple example without using random seed node :  
+
+![Text with random Seed 1](screenshots/random_seed_1.png)
+
+But, if you want to force using another seed for each iteration, you can use this node in the middle.
+For example, if you want to generate a different image every time. (aka : You use loop nodes not to compare or test results but to generate multiple images.)  
+Use it like that for example :  
+
+![Text with random Seed 2](screenshots/random_seed_2.png)
+
+Here is an example of FLUX with different prompt (hood/helmet) but same seed :
