I had a couple of days off and decided to have a go at making a simple pipeline to import designs from Figma into Unreal as native UMG widgets. It uses python for the most part, with a little bit of C++ for doing some widget modification.
Bear in mind, this is mostly just a first draft to check if the concept works so it’s far from polished or fully tested, but is still fairly useable in this state so I thought others might be interested.
Hi
I am trying to use your plugin, however I am unable to add it to my project. I get an error saying “The following modules are missing or built with a different engine version: FigmaImporter. Would you like to rebuild them now?”
When I say yes, I an error saying my project could not be compiled and I should try rebuilding from source.
Please help!
Hi,
The github repo itself doesn’t include a binary release so to compile the plugin from source you need to have a toolchain installed (eg Visual C++ with Visual Studio).
If you are using UE5.0.2 I’ve added a binary release you should be able to use: Release v0.1.0 Release · Phil-L-101/Figma2Unreal · GitHub
Download “Figma2Unreal_v0.1.0-UE5.0.zip” and extract to your plugins folder and hopefully that should open for you without needing to build anything.
Thanks a ton for the binary! The project opens up now and I was able to set it up to access the figma file. However there seem to be file writing issues now. I tried with both absolute and relative paths. Here’s output log…

No problem 
What have you set ImportDirectory to? “/Game/” is the base content directory so if you want a subfolder in your content directory use “/Game/MySubfolder/”
I definitely need better error handling/more informative messages.
Thanks again! I was giving the full path to the folder. Didnt realise “/Game/” was the base content directory. Its working now but I am getting a blank UMG canvas with some children. The figma I am trying to reproduce is quite complex but I though Id give it a try some new errors too. Here’s the log…

Hi,
Thanks for the logs, I’ll try and take a look over the weekend.
These lines:
LogPython: Error: KeyError: ‘1:3’
LogPython: Error: KeyError: ‘3:3’
Are referring to a Dict entry that can’t be found. It’s looking for the source component for a component instance but can’t find it. It may be to do with the order the API reads back components eg. If it finds an instance of a component before it has read in the source component it doesn’t know what to do.
If that is the issue, it hopefully shouldn’t be too difficult to fix.
That did seem to be the issue and I was able to replicate. I’ve updated the python script to write the instances after the rest of the document and that seemed to work for my little test so hopefully works for you too.
I’ll not update the release until I’ve done some more testing but since I’ve only changed the python code, the binaries from the 0.1.0 release should still work fine with the updated script.
Thanks a ton! its working now
