Hi,
We have an urge need to render our entire scene into a spherical texture ( 360 degrees ) map from a single point of view.
In lightwave, for en example, there is an elegant solution for this - by using advanced camera with 360 degree FOV.
I couldn’t get more than a 158.60 for Maya camera. I may try doing 6 renders by 90 degree, but it works not so well for entire map.
Has anybody solved it?

You might want to check out the fisheye lens shader over at Pixero:

I’ve tried JS_Panoramic, JS_Fisheye and Latlong.
None of them worked out for me. Is it now the only way is to learn compiling mental ray shader in Xcode, but that’s not my job.
Is there any other solution that works?

After hitting render button, js_panoramic gives an error “can’t find dynamic library, even though .so file is in right directory (Maya.app/Contents/mentalray/lib/)”

I found another way by batck baking reflective sphere, but it not rendering Ozone environment.

ahh, appears the Pixero shader was built for Maya6 - so probably a compatibility issue…
There is a fisheye lens in the p_MegaTK shader pack for Maya 2009:

After applying latlong or js_panoramic, render picks an other camera or viewport to render instead of camera with mr lense node (render setup with MR, raytrace). maya.rayrc is properly edited.

When Batch Baking MR into a reflective sphere, “render reflections” is on, the render is not calculating actual environment, but in the render from a basic camera, reflections work just fine.

Anyway, no result!

Even p_MegaTK FISHEYE is not exactly what I need, but it works!

*update
Looks like MyMentalRay picked up the Pixero lens source and has since updated the panoramic and fisheye lense shaders -

Found this fisheye shader in puppet’s shader pack:

Does anyone has a working solution for a spherical lensshader in Maya 2010 x64 ??

I am in a big need of a working 360/180 lens for Maya and Mental Ray.
Any other suggestions than the ones above are greatly appreciated.
Lat long lens crashes Maya every time I try to render. JS panoramic renders a black image. JS Fisheye lens doesn’t cut it (actually I can’t remember if it worked ) and the Puppet one doesn’t do it either (what I need).
There is obviously some demand for a little thingy like this. I call it little and of course and I don’t know how difficult it is to write such a thing. Ideally it will render a 2:1 image with a spherical projection. Max seems to have a wrap around lens but I don’t have access to Max and I am anyway not so good with it!
Well, thanks!
