CHUNKY rendering – quick fix missing textures

1. Go to .minecraft/versions and find the version your build is on. (If that version has no folder, you need to load Minecraft with it first). From that folder copy the version JAR file somewhere easily accessible.
2. Open chunky, in the right pane select OPTIONS tab and “edit resource packs” button. Click ADD and find and select the JAR file. Now click APPLY to apply the textures. It is fixed.
