![]() Common PFX in Hexels include blur and color adjustment. PFX are similar to filters in Photoshop in that they modify an existing image according to a set of rules. Post-processing (PFX) shaders will be used for our two examples. ![]() Final compositing of glow onto the Hexels imageĬurrently, three of these stages – PFX, layer compositing (blend), and baked color adjustment – support selection of shaders, including custom shaders supplied by the user.Post-processing effects applied to each layer.Drawing shapes and calculating low-level effects like halftone and texturing.Hexels incorporates shaders into every stage of its drawing pipeline: For Hexels users, this allows people to create their own blending modes and PFX, potentially doing things with Hexels that we at Marmoset never dreamed of. For developers, this is useful because code changes can be seen immediately without having to recompile and re-run. Another important feature of shaders is that they can be loaded and reloaded while the application is running. Shaders run on the GPU far faster than compiled code runs on the CPU, which means that post effects can be re-calculated every time Hexels draws without causing a noticeable slowdown. What is a Shader?Ī fragment shader is a short program that runs on the graphics card (GPU) to determine the color of an individual pixel. ![]() Please note that as we improve Hexels, this information may change, and any shaders you make may need to be updated for future versions, but we’ll try to keep as much backwards compatibility as possible. If you need a refresher on GLSL, visit the following links: A basic knowledge of GLSL 1.2 (OpenGL Shading Language) is highly recommended, but anyone with some programming experience should be able to do something with this tutorial. This tutorial gives an overview of shaders and how they’re used in Hexels, and then shows a couple simple examples of adding custom shaders, allowing Hexels to perform new tricks. Shaders allow these effects to be calculated in real-time for Hexels’ vector graphics. One of the coolest new features in Hexels 2.5 is the use of fragment shaders for layer blending and post effects (PFX). If you are at Bob Ross' levels of creativity you can create anything with any software though.Adding Blending and Post-Processing Effects Though to be honest all of these things could also be accomplished by using GIMP, wich is free. It's a bit finnicky to use at times but one of the easiest animations to make without having to redraw things all the time if you use a certain art style. You can set bones and layers to move things around on the timeline to make your animations. Optional: Spriter (pro): Used for animations only and it's fantastic at it. It really is great for that purpose alone. The best part about this software is that you can copy paste tiles and make mock up levels. ![]() Pyxel Edit: I use it for prototyping and creating (non-)animated tilesheets.Ĭan also do animations but I have little experience with that using Pyxel Edit so I can't tell you much. in good time.Īseprite: It's what I mainly use for creating backgrounds, textures, prototyping (basic) animations and making art for use in Spriter. Maybe i'll need to look up a guide and try again sometime and i'll probably will. I can see how useful it could be but again it's a bit too "advanced" for me. With that said I love the options to change your canvas and use Trixels to draw in "3d" so to speak. I have the full version on steam but i never really use it. I had the free version for a while and refreshed the free license a couple times (sorry developers) and tried it but I don't like it for reasons that i'm too inadequate to use it (properly). Marmoset Hexels: from what i've seen it can do anything that all the other programs can do.īut I find its interface a bit too "advanced". ![]()
