Unity SRP + Upgrading + Extension Developers.

SRP +Upgrading + Extension Developers.

SRP is a big step away from how things have traditionally been done with Graphics in Unity. Instead of thinking of Unity as an engine with one renderer it is now a platform that (custom) renderers can be plugged into.

This open Unity up in a number of ways:

  • Game specific stylized rendering
  • Experimental rendering algorithms
  • Optimized rendering for a specific game.

When undertaking this new approach we made some core, low level decisions on how we want the new system to work, a number of these decisions are divergent from existing unity. I want to take some time to explain these differences and why we made the decision to make these changes.

PS. Why does Power function have 3 instructions?

pow(a, b) = exp(log(a) * b)
exp(a) = exp2(a/log(2))
log(a) = log(2) * log2(a)
pow(a,b) = exp2(log(2)/log(2) * log2(a) * b) = exp2(log2(a)*b)

Pre-integrated Skin BRDF Texture in Colorspace

It is the article of pre-integrated skin BRDF texture.

This BRDF Texture is made in linear colorspace.
DiffuseScatteringOnRing.png

This Texture is made in gamma colorspace
(It process gamma correct after texture generation).
DiffuseScatteringOnRing_Gamma1024

linear colorspace texture(left) uncheck sRGB. It is linear texture.
gamma colorspace texture(right) check sRGB.
inspector

And I draw texture. (Unity rendering setting set linear colorspace)
It looks similar. but,Compare

Left zoom in. It has color banding.compare2

So, If you wanna high quality skin rendering, use gamma space BRDF texture.
