Calculating Normals in the Shader

This week we have a look at how we can recalculate our Normals in our Shader, for when we're using WPO or Displacement to alter the mesh shape.

There is a load of tutorials for beginners, this kind of intermediate stuff is hard to come by, especially of such quality and information density. Love it

The wealth of information within just this one video is amazing. I have been searching for quite some time for an explanation like yours.

Wow, yep it was both interesting and very very helpful! Thank you for all the teaching lessons.

Hello I would like to add that instead of using a constant value for the 'small offset' (that can start giving inaccurate results and if you get too close), you can add the UVs to the result of: the direction of the offset (for example r=1, g=0, b=0) *divided by* the function/node 'WorldUnitsInPixel'. That will give you a pixel perfect result 👍

hah. finally found an answer to calculating normals in the shader and its Tharle. Hello T!

Hey man, you know right topics ;) Great video as always, thanks!

Hello, is there a way to somehow smooth this DDX and DDY method. Great video

[Maxparata]

I'll try to do this with gerstner waves

Can you add all these materials in your Gumroad Pack so we can get them?
