Can I adjust the Camera perspective (aka: Focal Length)

    I have been trying different settings with the camera in blender; trying to see if I can influence the way the perspective is when exported (via Sneak Peek).

    I find the default setting to be too ‘flat’ looking; and it does not seem like something I can change. Am I missing something? Typical lens settings might be something like 50mm or 35mm for a slightly distorted fish eye effect.

    *NOTE: I have tried changing both the ‘Focal Length”, as well as the ‘Sensor Size’ in the camera properties in Blender. They seem to have no effect on the way the scene renders in the browser.

    You should be able to set the focal length in the Blender camera settings, but you will not get the fisheye effect, only the “zoom” effect. The way realtime 3D is rendered don’t really have the “faults” of a real camera or lens, so this is usualy done in post processing. So maybe this is a good candidate for a feature request…

    Good to know. It seems like something that we should be able to control. I kept wondering why the perspective seemed slightly ‘flat’, when compared to what I would see in the viewport in Blender.

    Do I need to make an official feature request somewhere?

    Thank you.

    The blender viewport is rendering in much the same way in terms of perspective, I think you even need to go to some panoramic settings to get any sort of fisheye distortion out of your renders, unless you do it with compsetting or something. But I guess with the viewport usualy taking less space on screen and having another “look” it might not feel as “flat” in some cases, so i guess a bit of playing around with the focal length might get you more of the look/feel you want in Verge too. And as you mentioned with wide angle lenses, they will deviate more from what you are used to with regular cameras then narrow lenses.

    There is the “Bug Reports and Feature Requests” section of the forum, but I am sure they will read this to, if not just make a post there, and maybe someone else will read and comment if they need it too.

    Actually, after playing with it for a bit; I realized the reason it seemed flatter then expected, was due to the ‘Focal Length’ & the ‘Sensor Size’ being set to the exact same size. If anyone is looking for a more dramatic looking perspective; make sure the sensor size is larger than the focal length. Then it does translate into the exported scene appropriately, and will reflect the way it is drawn in Blender. (If you are using ‘View > Cameras > Active Camera’ while in the viewport.)

    So no new feature needed! Which I’m sure is music to your ears . . . :yahoo:

    hehe. Glad you found a solution :good: I think lens distortion would be a great feature, but I don’t need it atm, so no request from me either ;)
