Camera Match in Maya with fSpy and Blender

[@bpampuch]

Before I add my 2 cents, I want to emphasize, I'm your big fan at the ArtStation ;-) Regarding this video (the fSpy part): - fSpy cannot determine the principal point unless your image has a 3-point perspective; in 4:14 - you get this orange circle in the right bottom corner, although your picture has its principal point in the middle (as it hasn't been cropped/shifted); you should never try to establish 3 nor 2 vanishing points for such images - as you've noticed this image has a 1-point perspective, you should have changed the number of vanishing points to 1 at the beginning and not drawn two Y lines because if you had matched Y precisely, you'd have got two parallel lines and an error in fSpy - for 1-point perspective you also have to manually determine the focal length I cover the above problems in my fSpy tutorial: kzbin.info/www/bejne/mpLMfoKPh516iZo

[@cincyilluminations8182]

I followed all of these steps, and it looks correct in Blender, but after importing it into Maya, the perspective is incorrect. Anyone else having this issue?

[@_fom1n]

I ran into the same problem with fSpy and Maya. Here’s how I fixed it: 1. Use the Angle Number from fSpy: Find the angle number under "Camera Orientation" in fSpy. 2. Set the Film Aspect Ratio in Maya: Input this angle number in Maya under the "Film Aspect Ratio" setting (in the camera's attributes that you import from Blender). 3. Adjust Fit Resolution Gate: In Maya, tweak the "Fit Resolution Gate" setting. For me, "Overscan" usually works best. This approach should help you get a more accurate camera match in Maya. Hope this helps someone!

Thank you for this video, I was actually looking for something like fspy for Maya. I know that I could've find out by myself how to import and export in blender the fspy camera but even if I have blender installed on my computer I do struggle in using it as it feels too different from what I've used to. So figuring out how to do this by myself felt kinda wasting my time meanwhile I could literally keep modeling other stuff in Maya, so thank you for for sharing this and saving many users time.

[@OnMars3D]

No problem, always happy to help!

[@stevenp6761]

Roughly how much time did it take you to build the untextured final model 23:34 ? Thanks!

[@OnMars3D]

I would consider the model to still be in "blockout" form as it only took about 30 minutes to create. There is a bit more detail that I still need to add. Hoping to have that done soon!

[@stevenp6761]

@@OnMars3D thanks! I need to practice more to speed up :) I wouldn’t do it in 30min.

[@pkminpkmon]

Amazing tutorial thank you! I’m just stuck on the part importing the FBX to Maya, I keep getting offsets in the Film Offset of the camera, making the Image Plane appear off-center. And when I zero it out, my perspective shifts. Really stuck here :(

[@alch_emist]

Same thing here Ok Nvm I got it : Select your camera > Attribute editor > Film back > Film offset > *set both values to 0*

[@OnMars3D]

There are a couple scripts people have made since I last made this video that seems to work: GitHub - Nathanieljla/fSpy-Maya: Import fSpy files into Maya search.app/b3hF3dTdcdcMmFTE7 GitHub - JustinPedersen/maya_fspy: Simple UI to import fSpy files into Autodesk Maya search.app/mbbVyGbFTKkuXUBX8

[@alch_emist]

​@@OnMars3D Thanks. I tried the most recent one. Although it is definitely a save of time, the perspective is still incorrect after importing the fSpy file to Maya (not by much but still). I've even tried matching all the values in the camera's attribute editor one by one but to no avail. Thanks anyway for the quick response. I will keep digging. 🙏

[@amineadimi7245]

Thanks a lot, we have a lot of problems at work with reference images from many diffrents cutomers, adjusting these ones in maya image planes is really a big headache! thanks again so much for this help

[@jrgensrensen3019]

Having a problem with fitting the reference image to the resolution gate, it has the same resolution, but it offsets a little to the right for some reason, its driving me crazy!. However it does not do the same with a normal perspective camera. How do i fix this?

[@hemanthsaji3606]

I am also having same issue. Did you find any solution

[@alch_emist]

@@hemanthsaji3606 Select your camera > Attribute editor > Film back > Film offset > *set both values to 0* (I'm a bit late)

[@hemanthsaji3606]

I have set the render setting to the same as the resolution of picture but the image plane is shifted slight towards Left from Resolution gate. When I hate the "Fit Resolution Gate" the height of Image plane match the resolution gate but it is still offset to Left I will DM you on Instagram with screenshot so that you can better understand what I am talking about EDIT: This issue is with 3-point perspective. 2 point perspective works perfectly . Does anybody know some workaround for 3-point perspective.

[@skfarhanfaruk5880]

Thankyou sir keep doing the hard work ❤️

[@OnMars3D]

Always welcome!

[@amineadimi7245]

Sorry but a last question, can i use fspy to set one layout from different images like in 3d (front, side, back, ...)?

[@OnMars3D]

fSpy doesn't work with orthographic images (blueprints) or images which lens distortion. If the reference images were taken with a camera and you can see the environment background good enough, then yeah, you can use fSpy with the images!

[@abladao]

I had an issue when I was setting up the image plane, the "Fit to resolution gate" did not worked. You know what may have been the issue?

[@OnMars3D]

You have to set the the resolution in you render settings so it matches the reference image, then it will automatically match in the viewport when you use the resolution gate.

[@BloodMoonOracle]

unfortunately. when I click the fit to resolution gate my image don't snap on it

[@blurbeta777]

Great Thanks Man!

[@orbitalpunk]

Hi, how are you rendering out the furnishings and shadows only so that it can be composited on top of the original photo? Are you using VRayMtlWrapper? When i use it it wont catch shadows on an enclosed environment. only on a flat plane.

[@OnMars3D]

I'm not using V-Ray Mtl Wrapper, just standard Vray Mtl. This is the benefit of camera matching so it closely aligns to your original reference.

[@OnMars3D]

I had to rotate the camera 90 degrees. If it still causes issues, recreate a new camera with the same position as the imported camera.

[@yuriyreva3609]

for some reason, my camera is shifted in Maya, although everything is fine in the blender!(( I tried to configure several different cameras, and all of them have an offset in Maya

[@OnMars3D]

They should have an offset in Maya, that's why we group it then rotate it with the pivot set to the world origin (0,0,0).

[@em.bassey]

Nice tutorial. I have issues with it though, When I import my camera into maya it has a film offset and i can't find any information on how to deal with that.

[@OnMars3D]

I end up just transferring the transforms and FOV/Focal Length of the imported camera onto a new camera in Maya. This prevents any rendering issues that I ran into when bringing over the camera.
