Please Help! Nodes Editor Blurring/pixelating 3D object

hello
i need to make the 3D object slightly pixelated/blurred to match the footage that im combining it with. Right now the 3D object (a helicopter) looks way to clean and has crisp edges… i need to make it look poorer quality.
How do I do this in the nodes editor, or is there a different section i should be doing it in?
Thanks

Have you tried using the blur node?

which options should i select?

i would maybe scale it slightly lower than your scene and then back to the original size.
should look a bit like this:



add a scale node and set it to 0.5
then add another and set it to 2

EDIT: just thought, set the second node to render size, then you can change the first to whatever you want without having to adjust the second

i tried the blur node but i couldnt get it to work for me…

so the node order would be
renderlayer image connect to- scale node .5 image connect to- scale node 2 image connected to- composition
it that the right order?

could you post a screen shot (prt scrn) showing the order it should be in?
thanks

i attached a picture of how i have it now…

thanks

You’re using an AlphaOver node, right? Try enabling the Convert Premul check box.

i figured it out
all i had to do was turn of Oversampling (OSA) and it removed the outline…
now i just need to figure out how to have particles cast a shadow (for a different scene than the one picture above…)

yeah that’s good. sorry i forgot to check this thread :stuck_out_tongue:
