A Unity project to remake the scene in Journey.
A demo image for the scene in the project :
The reference scene from Journey :
(Image Source: GDC Vault 2012 - https://www.gdcvault.com/play/1017742/Sand-Rendering-in)
A modified Oren Nayar model is implemented :
Height map(Normal map)
The terrain is separated into X-direction and Z-direction.
Normal map in X and Z direction is applied to different orientations.
TBN convert the normal to correct direction
The overall effect :
Well, simply, it is Bilnn-Phong model. I also tried the PBR but there is just a very vague improvement.
Not 100% sure what the noise function is uesd. Here is a fake effect to simulate the one in Journey.
The result without any screen-base effect:
Add Bloom: (Post Processing Stack)
Add Tone map and LUT :(Post Processing Stack)
Add Sharpen and saturation : (Beautify https://assetstore.unity.com/packages/vfx/shaders/fullscreen-camera-effects/beautify-61730)
