Creating 360 spherical environment map for Iray

in Technical Help (nuts n bolts)

Hey people,

I'm curious how I would approach creating a 360 spherical environment for Daz, to be added into the Spherical dome of the iray environment tab with the intent on delivering a product? 

So far my process has involved, creating an environment in 3ds Max 2016, with Vray 3, I position a camera in the center of the environment, go into the vray render options and set up Spherical render, which as suggests, renders a spherical environment. Hit render, same as EXR 

The render is 2:1 ratio at 4096

Next opening Daz studio, going into iray environment, adding the rendered image into the environment slot, selecting the spherical dome with floor option. Using the Iray viewport preview to see it ...

hm, doesn't look too great. Anything in that process, specifically on the Daz side that I seem to be missing?

On a side note, can Daz render out a spherical 360?

Thanks

David

    Go 10K pixels plus, thats very lowrez for a 360

    also maybe render two different exposures and use Picturenaut to make is a HDR image

    Is there anyway to scale the dome? seems like i cant quite get a scale to match between the character and dome. I could scale the character, but thats not good. Maybe i need to change the position of the original render cam in Max.

    One thing I really like about Iray Worlds product is that it essentially takes a short band of an image, replicates it three times around the horizon. Yeah, if you have VERY good reflections you might notice the zenith looks odd.
    The thing is, with a true spherical environment, you run into a problem that maybe 80%+ of the image is never being shown. There's an argument for, say, having a low rez shell and then a small high rez bit that you keep on camera.

    Just some things to consider.

    Set Dome Mode to Finite Sphere instead of infinite one. Than you will have some additional options like Dome Radius with which you can make it smaller.

    Thanks for the continued feedback! :)

    So I have a 10k spherical 360 background of a ruined cityscape. I also have a base geo, like a small patch for the center that is actually geo with textures. 

    I plan to do a few more with varying ruined dystopian landscapes.

    How do I prepared, package up the scene elements to make something that can be sold as a product? Do I just set up the scene with the elements and save this?

    I would package a scene (full load) and individual elements, too.

    Something along the lines of a light, any mesh objects, ground planes, etc as separate pieces to go along with the scene.  This way if someone just wants to load the HDR, that is a simple one click operation.  Same for the ruins.  Otherwise if it is just a scene, if anyone wants just one element of it, they will need to load it all and then hide or delete the parts they don't want to use.

    Also saving out the proper content types (prop, light, etc) tends to cause fewer problems with scene files 'losing' things.
