vray spherical rendering & mapping

hi mates,

i have a room and i put a camera inside it, render out a spherical map (vray settings camera type: spherical FOV:360)


if i know connect this file to a projection node, switch it to spherical, too, put this into the color chanel of a material, throw it on the same objects, this comes out:

how comes that the rendered image doesn"t fit the scene (scale wise)? the interactive placement is right on the same position as the rendered camera... any ideas?

thanks again for your time mates.

I don't think they'd work together. Camera projection is a Maya thing while spherical camera is Vray specific. You should stick to standard Maya camera for projection.

Work for me.
In the projection node, set the "fit type" to "match camera resolution".
And the fit fill to "horizontal".

What is your VRay build ?

yesterday i had some time to try it the way you described it but somehow i didn't get it to work.

maybe it's useful to see my steps that i go through so you can maybe see my mistakes:

- placing a camera into the room, defining the perspective and angle for the shot
- placing a secondary camera at the exact same position, but with zeroed rotations (projection cam)
- adding a vray attribute to the second (see image)

>overide global camera settings
>setting type to spherical
>override FOV
>setting FOV to 360 for a latlog


- creating a new material, renaming it to latlong_mtl
- attaching a prejection node to it
- connecting the rendered texture to it

- now i can try it both ways, with interactive placement (placing the 3dtexturePlacement node right at the same positions as our cameras

output from my scene cam:

do you see how the texture is a bit off? a little bit to big actually...

- or i can use the way you described with the camera

output now from my scene cam:

i can't even see a texture...

do yo have an idea why it doesn't work?

thanks again for help.

so i figured out a way. didn't use the projection node... rather remapped the uvs of the meshes.

now it worked pretty fine.
