Direct Farsi Type is a 3ds Max script from developer Nevil for typing Farsi text directly in the viewport. It handles a single job: entering Farsi text inside 3ds Max, and it earns its place in the ScriptSpot library as a focused utility for exactly that.
The tool is at version V01.1.0, an update that ignores upper modifiers. It is compatible with 3ds Max 6.0 and higher, so it runs across a wide span of releases from older builds through newer ones.
Direct Farsi Type is listed on ScriptSpot and is available here as free. A demo video is posted on YouTube, and additional information sits on the developer's NevilArt blog. For the current build and licensing terms, visit the developer's page.
