If you think OMD2 looks good, or maybe not, or has "something missing", then hopefully this Reshade Preset might help you up.

For those who know about Reshade and the Shaders it uses, here is what it uses:
- Adaptive Sharpen
- Ambient Light
- Bloom
- Clarity
- MXAO
- PPFX Bloom
- Reflective Bump Mapping
- SMAA
- Technicolor

Please note that you won't notice a huge difference in visual changes, they're rather subtle, but they are powerful especially when you try them in-game and play.

• Get Reshade from here; https://reshade.me/
  
• Install Reshade, follow instructions as indicated if needed. You don't need to download any shaders as they're included in my Preset.
  
• Get the Preset from here; https://www.dropbox.com/s/tg2txmzqezz65fu/Orcs%20Must%20Die%21%202%20Reshade%20Preset.zip?dl=0
  
• When you're done installing and trying Reshade, extract the zip file and move the files to "-\steamapps\common\Orcs Must Die 2\build\game"

You're done! Enjoy the looks.

Of course, this wouldn't be a good guide without comparison screenshots, so here they are.
