how can i get a clear shadow (in game)just like epic showing in Paragon trailer?
like this pic from trailer?

shadow_charater.jpg

notice this character have a very clear shadow in the game,so i wondering if i can adjust some parameter to achieve this level???

I use an asset from ark dev kit in Epic launcher for a example like this…

the whole body character can‘t draw good shadow,but the separate head showing the better result.

I have checked some parameter in console like R.Shadow.TexelsPerPixel and use dynamic inset shadow.

Did someone can show me how to make a character have a good shadow?

Thanks a lot~~~~~~
