I am having some problems with my latest project. In the first scene, I want to have a “tentacle of water” come out of real water, so I motion tracked the footage and I set up a tracking scene. Before even animating or doing the water simulation I tried placing a UV Sphere on top of my footage, switched to Cycles and made it glass, and I was immediately disappointed. Instead of the glass distorting the image behind it, the glass was grey. I am new to blender, and I know that I have to do something with the world tab or something with the background image to fix this. The reason I think it does this is because the world is set to grey automatically, so the glass reflected nothing. I think that because my scene is tracked, if my glass ball were to simply distort the background image and receive the color of the background image behind it it should work properly.
Does anyone have any ideas of how to do this? Some of my ideas included:
- Playing around with the compositor to get my glass to interact with the background image (Keeping in mind I do not fully understand what Blender set up when I set up the tracking scene)
- Playing around with the world tab. Maybe I can set the world to be grey, except the video in the background kind of follows and fits into my camera but not in a sphere around my scene
Thank you so much if you can help me. If you need download the .blend file to see my problem, I think it is possible to add any video in the background in the compositor and my video is not needed as long as my problem is fixed.
I know there is a way to do this in blender internal render but I want to do it in cycles so it looks better. Is there a way to duplicate this process in cycles?
