I need to import a animation png (with alpha) sequence into Blender, then put it on a geometry (a simple plane) to move some vertices (very subtle animation) and after that, export it again with the new deformation animation. How can i maintain the same pixel ratio/animation when rendering the output? i don't want or need Blender to soften the edges for example. (i want to render this on render internal, with plain colors, not adding any kind of light) I also need to mention, the frame 0 need to be the same as the static image, with the same pixel appearance, without any 'filter' appeared. Thanks in advance.
If you import in blender with images as plane addon, with emission or shadeless shader
And add an orthographic camera above to the center of your image, with orthographic view [ [
You can adjust the size by zooming a lot in a corner from the camera view (Numpad 0) and adjust the Orthographic Scale. Set color management to standard to don't have filmic transformation And sampling to 1 to avoid anti aliasing.
However, if you want to move the plane (rotate, or distort) the pixel will change as the raster sample the same pixels to in the same location. It will rasterize the image depending on the new transform, some pixels may stay the same, but some others will change.
