How to convert a Env Cube map to a Env Sphere map ?

#1

Hi all !

I’m currently searchin how to convert a Env Cube map (with a bunch of 6 square renders of my scene) to a Env Sphere map (single texture like an HDRI file) ?

I’ve try to create a Env cube utilities to use it as a Reflection source for a NURBS Sphere, and use the convert to texture, to create a unique Sphere Map. But I failed !

So help me … Can I create this map by using a Camera ?

try this

create a sphere…assign a high reflective meterial withouth diffuse nor specular…3) point ur camrea to this sphere …4) render.

or

try to do a render with very wide lens camera…just increase ur lens attribute

hope that helps.

hi,

you can take HDR Shop from Paul Devebec to convert your texture. Go to

I’ve found an another way … simplest…!

Use HDRShop and create a Longitude/Lattitude Map by using a Cube Map (Vertical Crossing) from my source texture… :wink: thanks to reply.
