Today, I experimented with Mental Ray shader to gain the soap bubble effect. It took me a while to get this look (Thanks DeJuan for helping me). It is still not the way I want it to look like, but it is getting there.
I originally had put flowers inside of the bubble but I removed it later after finding out that it did not turn out very well. The house is a model I worked on this week and textured yesterday.
I also tried to change the color of the sun of Physical Sun and Sky but completely failed.
