Shader View
As a long time Aseprite user I’m excited to finally share my first extension with the community:
a customizable external view to preview the current sprite with custom shaders!

Features
- Write GLSL shaders in a ShaderToy similar fashion to preview your workspace in realtime
- Export shaded results back to Aseprite for further processing or saving
- Add lua companion scripts with your glsl shaders to send additional data to the view or send raycasted input from it back to Aseprite
- Limited 3D features to load OBJ files and map sprites onto their uv layout
- A variety of examples to show the views capabilities and explain how to implement your own

Summary
This is mainly a tool aimed at people who have basic GLSL knowledge and want to integrate it directly into their Aseprite workflow. It should be pretty powerful already and a lot of complicated plugins that exist today would have been trivial to implement with an official shader support (wink).
Since shader compiling happens directly within the external view it is possible to edit and reload them without closing Aseprite even once.

Download
Finally here is a link to the Git Repository with the extension zip file inside the release section. (The current zip includes builds for most major operating systems but I could personally only test it on Windows (and Linux via a friend) so I cannot guarantee a Mac to load the view at all)
There is also a work in progress Wiki to help others setting up their own shaders.
I am planning to create an Itch.io page some time this week which will include stripped down zip archives for specific platforms only.
I hope this extension / tool is useful to the community and would love to hear your feedback. <3
