I ran into another annoying problem with Blender. I have a scene with an image sequence with an alpha (PNG).
The sequence is applied to a plane. I have UV mapped the plane, so I can see the sequence in the 3D view.
The image sequence is produced by After Effects. What I am doing is animating a 3D object on top of the plane. I am synchronizing the 3D object with the animated alpha rip in the image sequence.
So my work flow is I render out the movie in Blender, look at it in After Effects, then re-render the source for the image sequence rinse and repeat.
The problem I am experiencing is that Blender refuses to “let” go and reload the new image sequence. So even though I have an image mapped sequence on disk, Blender has, somehow, cached the image sequence in memory and is rendering from memory. I didn’t think this was possible, but that is what I am experiencing.
Even when I completely deleted the image sequence from disk, I would press render and see the image map being rendered. Where is Blender getting this map from? Is it just fetching is from it’s own internal memory?
