Intense camera scaling and rendering fail

[Hazoc]

Hi

I have imported a FBX scene from maya. I need to uniformly scale it down and this works fine, except the cameras get screwed up. Missing polygons, hair not rendering, etc. If I create a new camera with identical settings, it works nicely. I was wondering if theres a way to make the original cameras forget that they were seriously downscaled so I could render correctly without making new ones ?

Try resetting the camera's pretransform. To check if it has one, middle-click on the camera node in the network view.

The camera doesn't seem to have any pretransforms.

I tried switching and removing it's position in the hierarchy and parenting it under a new null. Now the rendering artifacts seem to be missing. But also various simple objects,like the torus I created for the test. 3D weirdness.

Maybe it's the camera's clipping plane parameters then? <shrugs>

How about doing the scaling in a node adjacent to or below the camera? Scaling the camera is almost always a really bad idea.

Import camera channels to chops, scale it down there, and export back on place. This gives you the same effect as scaling camera object itself but it's save from rendering perspective.

Hi there. here is another way I used via xsi to houdini .

In xsi there is a 10 time difference in the scale .

All you must do is adjust the preset and the FOV by hand

That is if maya has collada.

Here is the snap shot to import cam with another scale via collada
