    3D Using Shaders disables 3D Fog

    I'm hoping this is only a simple thing to fix, In my 3D game I use the default GPU Fog to obscure things in the distance, I also use a shader to tint sections of rooms in my game with a certain colour to make it lighter or darker. However if I use a shader on anything including just a normal...

    Shaders What's a good place to learn shaders?

    I'm absolutely hopeless for finding a good tutorial. Basic, easy-to-understand tutorials preferably, for obvious reasons. I really want to stick some kind of old scanlines/screen-burn type shader in my game but I don't know ):

    Question - Code What GLSL version is Studio v2 using?

    Hi all! I saw that v2 of Studio now has nice and simple ways of creating your own vertex and fragment shaders, but nowhere in the manual did I see the current supported version of the GLSL syntax. For all target platforms it says we can use GLSL ES and it also mentions that for HTML5 we need...

    Shaders [solved]Shader pow function

    I'm working on a shader that contains the line: float s = mix(r.x, (sin((iTime * 2.5 + 60.0) * r.y) * 0.5 + 0.5) * ((r.y * r.y) * (r.y * r.y)), 0.04); color += pow(s, 70.0) * (1.0 - v); When I try to compile, it gives me an error saying I should use abs on the "s" variable because the base...

    So I've been working on a volumetric lighting effect, and I've successfully achieved it with post-processing. Post-processing does have it's downsides and I did recreate this effect in forward-rendering, but I can't find a way to make it look nice as of yet. Therefore I'm sharing a video using...

    Shaders Getting pixelate shader to look right

    I'm trying to apply the pixelate shader (free from the marketplace) to one of my objects. However, it's not looking right. Drawing a circle with the shader on doesn't seem to have any effect, and drawing my sprite just kind of results in a chunky mess. I'm not entirely sure what I should be...

    kinda hit a strange road block in GMS2 today. I'm trying to use a depth buffer, but in order to get that far, I need another camera and perspective into the world. For some reason, the second camera is always static and flat unless I place it in the same object as the first rendered perspective...
