Thanks for the reply.
I've checked to make sure the "pixelated" box is ticked, but there is still some interpolation going on.
I have attached examples below:
This is a test sprite which was screen captured at 500% zoom, and where pixelation is maintained:
And this is the same test sprite screen captured inside laigter with pixelation turned on, also zoomed at 500%, :
The difference between the two is the first has no interpolation, where as the second one has some bit of it, most noticeably with dark outlines.
I was hoping that the normal map lighting could apply with the pixelation maintained. I could then simply take a screen shot in the preview and use that as an overlay to simulate something like a muzzle flash. But currently, there is some interpolation which gets in the way. See below image for the difference:
I'm not sure if its possible to maintain the pixel look 100% (more or less to remove those dark lines). But if it is, would be great!
Thanks again!
