The Rock Essentials helps you:
It’s everything you need to take your outdoor scene to the next level.
If you look out your window, chances are you’ll see rocks.
You’ll find them in every environment on earth: the desert, arctic, underwater and even other planets.
In fact the human eye is so used to seeing them, that if you made an outdoor scene without any, it could look incomplete.
Simply put:&amp;amp;nbsp;rocks are an essential part of making outdoor environments feel real.
The traditional approach for making something CG follows these 2-steps:
1. Model the object
2. Find a texture and apply it
And while this works well for most subjects (architecture, cars, humans etc.), rocks are different.
With rocks, the shape and it’s texture are directly&amp;amp;nbsp;linked. Meaning that when the shape changes, the texture does too:
So when you compare that to the the usual 2-step process, you can see why it doesn’t work:
Rocks created this way will always look fake, because the texture has no relationship to the shape.
For years I just assumed that’s the way things would always be. Until I discovered…
Photoscanning is completely different method. Instead of starting at the computer, you start with a camera.
You go outside, find a real rock, then take multiple photos around it:
You then import the photos into some photoscanning software and let it magically create a mesh out of thin air.
But what makes it really powerful, is that as well capturing the shape, it also captures the exact&amp;amp;nbsp;texture, and maps it to the mesh. Resulting in a model that’s&amp;amp;nbsp;physically accurate&amp;amp;nbsp;to the real subject.
Photoscanning is awesome, but there’s a reason it’s not as common as you’d think…
While it sounds like it’d be fast, proper photoscanning actually takes a looooong time.
You need to:
Find and photograph the rock under ideal lighting (1 hour)
Import the photos, and let the software generate the model (3 hours)
Retopologize and bake into separate maps (1-2 hours)
Configure the material and settings for use in Blender (1-2 hours)
All up, the process for photoscanning one rock, can take a skilled artist&amp;amp;nbsp;5-8 hours!
