In the process of modelingWe establish the basic geometry of the object or character.
We use 3D modeling tools such as Blender to build detailed shapes from simple primitives. Like texturization is the next step where we apply images and patterns to the surface of the model, bringing visual features to life.
Textures can be created using Photoshop or GIMP.

A common practice is UV mapping, where we unroll the 3D surface on a 2D plane to get precise control over texture placement.
This step is crucial to achieve realism in the visual aspects of the models.

Sculpting and Retopology

The sculpted is used to add fine details and achieve a more organic look.
We use specialized software such as ZBrush to carve details in high resolution.
This process allows us to modify the topology of the model and adjust the density of polygons where necessary.

Rheopology is the next step in simplifying the mesh of the sculpted model, ensuring a clean structure that facilitates animation.
During retopology, we reduce the number of polygons without sacrificing visual quality, allowing for smoother animation.

Rigging and Skinning

The rigging involves creating a skeleton within the 3D model that will allow it to move and animate.
We use bones and controllers within the animation application to define how the model should deform during animation.

At the stage of skinningWe adjust how the geometry of the model deforms according to the movements of the skeleton.
We assign weights to the vertices to determine how the bones influence the mesh.
At the end, we check the movement to make sure it is realistic and fluid.
