I am currently trying to make a cube sit on the ground in real life footage I filmed, but I am running into a brick wall. When ever I enable the settings for the sky to be alpha and my 3d object to sit on top of the scene, blender is not rendering the video. This method i am using usually works, the only reason this is not working is because it may have to do with this .blend being imported from 2.49 to 2.69.
Because I cant seem to get blenders camera tracker to work the way I want it to. I decided to try an external tracker. I tried voodoo camera tracker and that didn’t work. Then I found a program called Pftrack that exports tracking data into .py scripts. Unfortunately pftrack can only export the .py scripts into blender v2.49, if you were to try and export the script in blender v2.6x series then you would get an error. so I opened blender v2.49, executed the script, saved the .blend and opened it in blender v2.69, And now I’m having this problem. The executed camera data works but its just the rendering that’s not.
On the left of the two images I posted you should see what I want the render to look like and what it actually looks like on the right.
Is there anyway to fix this?
If not. Does anyone know of any external 3D tracking software that can export its data to blender 2.6x series?
