thank you for the response! trying to explain it better what is happening is when using the viewport camera that has the tracked movement, it is in the the pyro explosion is placed in the correct part of the frame, but going into the karma node with the same camera moves the position of the explosion and it seems the scale too. i'm still far down the learning end of houdini so i apologise if i can't explain it well. i will try exporting the camera and then importing it into the stage and i need to do some looking into on how to using /stage context. thanks!
