About MNPRX

What is MNPRX?

MNPRX is a real-time stylized renderer plugin (currently only for Autodesk Maya™) with an intuitive toolset for art-direction at different levels-of-control. Check out the available styles in our growing style library here.

Can I use MNPRX commercially?

Yes, with the MNPRX Indie Version (for private individuals and teams/small companies up to 10 employees) or MNPRX Studio Version (for big teams and companies with 11 employees and above), which can be purchased here.

Will MNPRX work on my system?

Currently, MNPRX is only available for Windows 10. For Linux (CentOS) and Mac, we can build MNPRX upon request for bulk purchases (more than 10+ licenses).

Is my computer strong enough to run MNPRX smoothly?

To run MNPRX smoothly, a modern graphics card (2+ GB is recommended). For higher resolutions and scene complexity, more is needed.

Can I transfer a license to another computer (floating license)?

Yes, this is possible, but only after 24 hours have passed from a previous activation. Read more about it here.

Can I change back to the normal viewport?

Changing renderer in the viewport
All viewport renderers are listed here.

Yes, just change the viewport renderer from MNPRX to Viewport 2.0.

NoiseFX and PaintFX

I deleted the construction history, how can I still animate PaintFX?

Animating PaintFX requires the construction history created with the vertex color sets to keyframe the values. You will need to recover the required construction history.

  1. Export the PaintFX with the Import/Export Tool.
  2. Delete the PaintFX using the MNPRX Toolbox.
  3. Add history -> Edit Mesh->Transform
  4. Import the PaintFX back in with the Import/Export Tool. The construction history will be in place and you can now animate the PaintFX values.

Troubleshooting MNPRX

My scene is all white once I load MNPRX

There are many reasons why this might be happening, we’ll list them up from most to less frequent

  • The world scale is not properly set up for the scene.
  • The scene might have been created with an older version of MNPRX and you need to update the materials.
  • Your GPU may be running out of memory. This is unlikely, but can happen if a lot of textures are in the scene.
    You may clamp the resolution of the textures to help alleviate this problem.

Some objects are missing when I render

Your GPU may be running out of memory. This can happen if you are rendering at big resolutions on a weak GPU or if a lot of textures are in the scene. You may clamp the resolution of the textures to help alleviate this problem.

Batch render completes without rendering anything

Maya’s RenderBatch Render tool is broken when MNPRX is in the MAYA_MODULE_PATH environment variable. This even happens when the plugin is unloaded, which seems quite odd (if you know why this is happening, we’d love to hear how we can fix this).
As an alternative, if you are using another renderer, please consider using RenderRender Sequence instead or batch rendering from the command line.
If you really need to use the Batch Render tool within Maya, temporarily delete the *MNPRX variables from the *Maya.env file, use the Batch Render tool and either place the variables back or re-install MNPRX.
