how to prevent some objects from being illuminated by environment texture map ?

[metaclay]

1. I use cycle and set the world lighting by using environment texture map. How to make some objects to ignore this environment ambient/illumination ?

2. Also how can i rotate or offset the texture of the environment map ? is there any way like loading this into the node editor so then i can apply or add transform node ?

If you correctly added a texture to the environment, you should already see it in the node editor when set to “World” mode. Just add a Texture Coordinate > Generated and a Mapping node.

Concerning your other question:
You might need to create two scenes with different environments and combine the renders in compositing later.
