I have a couple of questions.
1. I have not been able to shade an object that would be strong color + strong reflections, like copper (http://homegardenvibes.com/wp-content/u ... 5_rwet.jpg).
When I try to shade the object, the reflection is good but the orange color is gone, or the color is good but the is no reflection.
See this one :

Do you guys have advices of how to do this? Is there a node for "boosting" up the diffuse color or something?
2. There is something weird about the bump map. I have a bean bag seat that has a diffure material of a fabric. The diffuse channel has an UV map of the brown fabric. Everything is nice, soft correct shadow. When I set the UV bump map (same size as diffuse map), the shadows turn sharp, harsh and ugly. What could be the problem?

This happens with many objects, especially with sofas, pillows, etc.
3. I read often about using HDRI-lightning in INTERIOR vizualizations. I understand that using HDRI-maps in outdoor scenes and for example in studio setups is great for producing nice reflections and lightning, but for INTERIOR scenes I don´t get how HDRI should be used. How does the HDRI as an enviromental map light interior scene when there is walls and ceiling in between the enviromental map and the room?
Can someone explain, how the HDRI maps should be used with interior scenes, thanks!
