A focused utility in the superhive library, PDF as Reference covers a broad span of Blender versions from 2.8 through 4.1 and ships under the GPL license, with a recent update aimed at newer 4.0 and 4.1 releases.
PDF as Reference is a Blender add-on that brings PDF files into the 3D workspace as reference images. Instead of converting pages to image files by hand, it imports multiple PDFs at once and places each one on its own plane, with every imported PDF keeping its original quality for a crisp, accurate reference.
To keep scenes tidy, the add-on automatically generates and assigns a unique material to each imported PDF, which prevents material conflicts. It works from Blender's existing import menu, so the process fits into a familiar workflow. Setup relies on the PyMuPDF library, and the add-on includes an automated installation process for it, with manual instructions provided if needed.
PDF as Reference is distributed under the GPL license and lists support for a wide range of Blender versions, from 2.8 through 4.0 and 4.1. A demo video is available, and the developer states they are active and open to feature requests.
Pdf As Reference is best for artists and designers who need to import and manage PDFs as reference images inside Blender.
Pdf As Reference is completely free to download and use.
PDF as Reference depends on the PyMuPDF library to bring PDF files into Blender. The add-on includes an automated PyMuPDF installation process, though the developer notes a manual step may still be required. To install it manually, you open the Scripting workspace, bootstrap pip through the Python Console, then run a short script in the Text Editor that installs PyMuPDF. After that you restart Blender and enable the add-on. The developer states they are working on removing this manual step.
PDF as Reference lists support for a wide range of Blender releases, from 2.8 up through 4.0 and 4.1, including the 2.9x, 3.x and early 4.x series. A recent update was made specifically to ensure the add-on works with newer versions such as 4.0 and 4.1. When running one of the listed versions, the add-on integrates with Blender's existing import menu. For the full current version list, check the developer's page.
PDF as Reference can import multiple PDFs at once, placing each one on its own individual plane as a reference image. It automatically generates and assigns a unique material to each imported PDF, which prevents material conflicts and makes scenes easier to manage. Every PDF also retains its original quality for a crisp, accurate reference. The whole process runs through Blender's existing import menu, so PDFs come in without being manually converted to image files first.
PDF as Reference is listed as free in this catalog. Licensing and pricing can change over time, so for the current terms it's best to check the developer's page directly. The add-on is distributed under the GPL license. If you're evaluating it before installing, a demo video is available, and the developer invites messages with feature requests or questions, stating they are active and willing to help.
