for transparency effects. PD Pro 4 was updated to make use of multithreading with multiple processors. Features include realtime filters that update as you adjust them in full screen, and a particle painting tool that paints things like trees and grass, and can also be animated to produce typical particle system effects. Animation tools include a timeline for applying filters, an exposure sheet, a keyframer to move images around, the ability to paint with animated brushes, a batch processor, pulldowns and retiming, and other items of use to animators and motion graphic artists.

. Lua scripting is also available in other digital painting programs, such as ArtWeaver and Twistedbrush. Some implementations have their respective extensions. When the core GIMP-original gluas syntax is used without proprietary extensions, these imaging filters can be shared and used across these applications for the benefit of other users. Some extensions from Project Dogwaffle have found their way also into others such as ArtWeaver. In 2011, Dogwaffle was split into ''PD Howler'' and ''PD Artist'' lines of products, with the Artist label for those not requiring animation tools. Around v9, some 3D features started using the GPU. In v9.5/9.6, the 3D Designer had a fairly major addition of features for more realistic looking landscapes, with erosion, sediments, and texturing based on elevation and slope. Version 9.6 became the first release available on Steam for game developers. As of early 2016, version 10 was the latest so far, and development continued for new features, and another release on Steam. Several additional features were released through the year as add-on plugins such as a Worley Noise filter.
