Creating an Accurate Camera in Maya with fSpy

In this tutorial, you'll learn how to create an accurate camera in Maya using fSpy. fSpy is an open source software for still image camera matching made by Stuffmatic, which allows you to match the camera position, field of view, and focal length of a photograph to use in your 3D scene. In this guide, I'll cover a few basic tips to use fSpy effectively.

Whether you're a beginner or an experienced Maya user, this tutorial will help you to create more realistic and accurate scenes by using fSpy to match your camera position and settings.

To everyone that is struggling to get an accurate result: It is very important that you set the correct focal length, otherwise the scene can differ by several units and also be misaligned/tilted

In Maya for correct color management, I recommend to add these lines to the python script:
1. after this line: cmds.setAttr(image_plane+'.depth', imagePlane_depth)
add:
cmds.setAttr(image_plane+'.colorSpace', 'sRGB', type='string')
cmds.setAttr(image_plane+'.ignoreColorSpaceFileRules', 1)

2. after this line: cmds.setAttr(projection_fileNode+'.fileTextureName', image_path, type='string')
add:
cmds.setAttr(projection_fileNode+'.ignoreColorSpaceFileRules', 1)
cmds.setAttr(projection_fileNode+'.colorSpace', 'sRGB', type='string')

Cheers, D

I can confirm that this works in Maya 2024, however to anyone who is not used to using custom scripts, make sure to click the MEL button right before the script command prompt line to switch it to Python. I was wondering why this wasn't running for 10 to 20 minutes until I decided to look up "Using Custom Scripts" and had another tutorial highlighting that Python (not MEL) needs to be enabled.

Worked like a charm! No more struggling with the crooked native fSpy export to Maya which doesn't work at all

Incredible work Kurt, thank you so much!

[abdulrhmansoliman]

this is simply priceless, I'm very thankful really keep up your fantastic videos man ! 🥰🥰

[murray-xrpl]

Thank you so much for this! It worked fine mostly, the only issue I had was the camera and the image plane got imported far away from the base point, but I was able to just move it closer towards my scene and rearrange it a bit and the perspective was still nicely in place.

Had issues with my image, perhaps because it is portrait (Taller than wide). fSpy outputted a focal length of 22.25, however it did not look correct. Turning it down in Maya to 14.85 gave the correct result. This so happened to be 2/3 of fSpy's value which was the device aspect ratio for my image (980x1470 => 0.667). So perhaps fSpy doesn't factor this in where it should.

Hi, first of, thank you for the plugin, however theres an error with the import script! Running the original returns this error: Error: ModuleNotFoundError: file <maya console> line 1: No module named 'kb_fSpy_camera_maya'

I fixed it with this import code:
import kb_maya_fSpy_camera as fSpyCam


I'm leaving this comment here for anyone having issues running this, cheers

[samuelwilson]

Thanks for the script. When I press "Create Camera", I get the following error?
"# Error: AttributeError: file line 16: type object 'int' has no attribute 'from_bytes' # "

Hi Kurt, thank you for creating this tool! I just tried 2 different images. They are fairly close but definitely not accurate enough compared to what I'm seeing in Fspy, they both have wider angles of view. Do you have any thoughts as to why this would happen?

[RemotelyHuman]

This might be my lack of experience showing but when I import into Maya 2025 the origin is just slightly off. is this happening for anybody else?

Thanks for the video! I do have trouble when importing into Maya, camera just doesn't match and that midpoint is off as well. However works great in blender (same file). Any clue where it needs extra care when it comes to maya (....as always). In fact when I export from Blender to Maya it also works so not sure. Cheers!

Hi Kurt, Can you provide some steps to install the fspy plufgin in maya ? I am trying the same procedure that one uses to install the plugin in maya but it is not opening after I add it to the shelf. I am using Maya 2022

[Tubbs]

How do you set up multiple cameras with different angles of the object im trying to make ?

[rudy]

Hey bro, nice tutorial but Im having some Error on the script, it show "# Error: ModuleNotFoundError: file <maya console> line 1: No module named 'kb_fSpy_camera_maya'" . It used to be working fine ytd but it just error today . Anyway for me to fix it ?

[theapexpredator]

I just tried it, but it didn't work for my case. I'm not sure if there is something wrong with my photo, but I keep running into a similar problem.

I'd love to troubleshoot it with you and see if a solution could be found, or at least an explanation...

[tinkuop]

bro cant insall, can you please make video how to install step by step

[amitnegi]

hey i dont get any problem while importing scripts but the only problem i faced is the camera i imported is far away from the grid and when i started blocking it overlap the reference picture and half of the overlap mesh hide.please tell me the solution for it, btw great video it helped a lot.

[mightguygaming]

Hey bro i wanna ask can we match perspective in syntheyes and then bring it to maya
