Particles are not killed when video is rendered I have 2 images (as planes) and a particle emmitter in between. When previewing, no particle come through the image as in this screenshot: Link

When rendering the video, the particles do come through the image (as plane), like this: Link to second screenshot. Why is this happening? I have "Collision" physics with "Kill particles" checked for every mesh and node.

Here is another screenshot which describes this pretty good:
I can confirm that the collision system (die on hit) is not 100% accurate or at least is not calculated when two meshes touch (it could be also because of settings from the "integration" panel under physics - like integration type, Timestep or Subframes).

The solution I can suggest is to create a duplicate version of your collision mesh and move it a little closer to the emission object. Set this duplicate as collision and hide it from the render.

It will act as emitter killer, but it won't be rendered.

The distance from the original object should be something around the RADIUS of the object you are using as source (calculated also with in mind the Scale of Render simulation).
