Camera view without perspective

[TomA]

How can I create a Vray camera view for plan, section and elevation orientations i.e. without any perspective/focal length.?

This is quite useful. :-)

You just need to tick the 'Orthographic Projection' box in your camera settings.

 

Edit: Oh, Vray cam I see!

Andy - Thanks, but it still has a focal length?

 

Edit: sorry, should have read the instructions!

Andy, the rig you posted a link to only seems to be applicable to elevation shots, not plan views.

 

Any ideas how to get an orthographic plan view with a Vray camera?

 

Thanks

It does still have a focal length because it creates a vray camera. But it tries to "fake" a flat ie front,left,right viewport. You can create a rig and then rotate it to be a plan. Alternatively, create a vray camera with a really small lens but move it away a big distance to flatten out the perspective. That's effectively what that script does. The rig is much handier though.

 

Unfortunately, it the only way as you cant render a front "elevation" in the front viewport if your setup rendering with Vray sun and exposure. It does give good rsults doing it this way though.

I'm afraid it will always have a focal length; without trying to sound cheeky, the clue is in the name "physical camera". If you want a truly orthographic camera you must use the standard max camera. This will work fine, providing you adjust your lighting intensity to suit.

you can use the Vray Exposure Control in Environment and Effects, and select mode: from vray camera, node: select a correctly exposed vray camera in your scene, and render the top viewport or a standard camera looking down at your model, having the orthographic option on.

This is how I do orthographic renderings (with standard camera and vray exposure control), I don't use any scripts.

 

Good luck!

^ I always use this method too
