I really think ChaosGroup have really simplified their interface in VRa圓 for Rhino far too much.īut hopefully thanks to you and Nathan I can now start to make sense of this, now I can see how the camera lens settings in Rhino are controlled. I am in separate communication directly with ChaosGroup about VRa圓, but what frustrates me is that VRa圓 for 3DStudio retains the controls that were in VRay2 for Rhino. Basically we have to edit part of the ‘visopt’ script, which is not in the interface. It is also now complex to render in point cylindrical from VRay 3. The problem I am faced with is that VRay now depends on the Rhino camera geometrysettings for the resultant rendered image. The problem I am faced with in Rhino 6/VRay 3 is that the VRa圓 interface has been cut back hugely. It didn’t matter what the Rhino camera lens was because the render was completely controlled in VRay. This was reasonably straightforward in Rhino 5/VRay 2 because there were a lot of controls on the VRay2 interface. What I am actually trying to do is render out 90 degree views using the ‘point cylindrical’ projection (in VRay). It is the horizontal field of view I am trying to fix.
It suggests to me that the Rhino 6 camera is set up incorrectly.Ĭould McNeel look into this, is there a there a fix? If I set the camera lens to 60 mm I get 39.6 degrees. If the camea is set to 50mm I actually get a horizontal field of view around 46degrees (rather than the expected 39.6 degrees). The problem I am faced with is the Rhino cameras appear to be incorrect. VRay 3 then renders the same view geometry. It is then very easy to check what horizontal field of view I get in the viewport window. I can change the Rhino camera lens to give whatever lens I choose. It includes 360 columns located in a polar array around a central camera.
I have created a very simple model to test this. So I am expecting the Rhino 6 camera to give the same results. There is clear camera/lens geometry that can be calculated eg an 18mm lens gives a horizontal field of view of 90 degrees and a 50mm lens gives a horizontal field of view of 39.6 degrees. I am using rhino (and VRay) to replicate the same view as taken by a camera.
