    Hi bruening,

    As an enterprise user, please reach out directly to your CLO representative in the future :) As for this question, we're waiting for feedback and will then let you know.

    Hi bruening,

    As the V-Ray render currently integrated in CLO only provides a slide-UI for directly entering FOV, what determines the FOV in an actual camera is sensor size (film gate in analog cameras) and focal length, so the FOV of a 50mm lens may vary depending on the sensor size: https://shotkit.com/field-of-view/
    Even when using a 50mm lens, the FOV can vary from 40 to 15 depending on the camera sensor type: https://www.nikonians.org/reviews/fov-tables

    Hello and thank you for the insightful response!

    I understand now that the Field of View (FOV) can vary significantly depending on the sensor size, even with a fixed focal length like 50mm. Given this, could you please advise on the approximate FOV value I should use in CLO 3D to simulate a 50mm lens on a full-frame camera? I'm aiming to achieve as realistic a perspective as possible for my projects.

    Am I right that it would be 27 degrees in portrait and 39.6 degrees in landscape???

    Thank you once again for your help!

    Hi bruening,

    Our suggestion is to adjust until what you see on the CLO screen feels most natural, as the view seen through a 50mm lens is closest to how humans see objects. The FOV of the CLO renderer quantifies the visual distance from the object (avatar and/or garment) in the 3D window, rather than the view from the camera, and provides it in the UI. Furthermore, many objects displayed in the 3D window are not actual 3D objects as we know, but are “made” to look 3D on a two-dimensional plane. So there is a lot of difference between what we see in the real world and what we see through the camera. The calculation of 27 degrees in portrait and 39.6 degrees in landscape is approximately correct when calculating the visual range of the actual human eye. However, in the camera world, it would be more common and easier to understand to say that it is calculated by the image size captured on the actual film or CCD sensor.

    Thank you for your assistance. I've decided to adjust the viewport to a 3:4 aspect ratio to achieve a portrait orientation. I'll set the camera to a 27-degree angle and then zoom in on the object. This approach should yield the most accurate results.

    Once again thank you for your help!
