It's not doing anything? Have you checked the log file? Did you make sure you copied all of the shader toolkit script? It's a large script so it's easy to accidentally not copy the entire thing - wish the wiki had an option to be able to add a button to select all the text inside of the code block as it would make things so much easier. I might look into a button again at some point...& you definitely set it as a definition script? Not "execution" type script. If you unticked the checkbox then it will require the script to be manually loaded which isn't desired as we need it to automatically load on game launch.https://i.gyazo.com/88924f20f78d9b95b93e23f6e0ee0db4.pngAnyway, both shaderNoise() & shaderAddEffect() functions are working ok for me as you can see in the screenshots below.

Now I created a script under "Scripts", called it "Shader", checked it as a definition script, and pasted the shader Main Script into that script.I then made an execute script action for the beginning of a scene, and pastedgame.ShaderExclude = eShaderExcludeInterfaces -- exclude fonts, cursor and interfacesshaderNoise(1, -0.1, 0) -- activate noise in 0ms with a soft black grainshaderAddEffect("tv1")into that.However, nothing happens when I run the scene... What have I done wrong?

Actually you can use the openGL shader for that. There's already a premade old movie effect.If you haven't already included the shader toolkit in your project then you need to create a new script in the script section of the editor & copy/paste the script from this [url=https://wiki.visionaire-tracker.net/wiki/Shader_(CMS)]page[/url] into it.Quick note: the shader screen fx presets affect the entire screen including interfaces & mouse cursors, so if you want to exclude them from the effect you need to add a line of code to the top of the shader toolkit script.[code]game.ShaderExclude = eShaderExcludeInterfaces -- exclude fonts, cursor and interfaces[/code]... that will exclude cursors, fonts & the mouse cursor from the screen fx. Alternatively you can use...[code]game.ShaderExclude = eShaderExcludeTextsAndCursor -- exclude fonts and cursor[/code]or...[code]game.ShaderExclude = eShaderExcludeCursor -- exclude cursor[/code]Moving on... for the noise effect you can use 2 different options. Either way you will need to add the required line of code into a [b]execute a script[/b] action part.1. shader noise[code]shaderNoise(1, -0.1, 0) -- activate noise in 0ms with a soft black grain[/code]2. old movie effect[code]shaderAddEffect("tv1")[/code]For more information on the shader check out the shader sections available on the [url=https://wiki.visionaire-tracker.net/wiki/Compiled_Index_of_Lua_Scripts_for_Visionaire_Studio#Shader_Toolkit]script index[/url] page of the wiki.Quick note: I've not gotten round to documenting all the shader effects yet, but you can probably get the gist of how they work from the ones I have finished documenting.

Check out the shader fx object template made by Unreal here: http://www.visionaire-studio.net/forum/thread/visionaire-shader-toolkit-demo/It should show you how to apply shader effects to objects. It's also possible to write custom effects & shader scripts, but it requires a decent understanding of C / GLSL, which is beyond me as I've not got the patience to spend 4+ years learning the basics.

i used it on mine, but predefined by the project itself (pixel game). But i never switched it ingamr, so i dont know if it affects anything... You could use a pixel shader maybe to simulate this...
