1. Concept & Reference Gathering
   Before diving into modeling, I collected various reference images of brake calipers to understand their design, shapes, and details. This step is essential for achieving an accurate and realistic final model.
2. Modeling in Blender
   

Base Mesh Creation:I started by blocking out the basic shape of the caliper using simple geometric forms like cubes and cylinders to establish the overall proportions.

Detailing:With the base mesh in place, I added intricate details using Blender's modeling tools. This included using the extrude, bevel, loop cuts, and knife tools to refine the model.

High Poly Model:I then transformed the base mesh into a high-poly model, focusing on adding smooth surfaces and rounded edges by applying subdivision modifiers and ensuring proper smoothing.

1. UV Unwrapping
   Once the high-poly model was complete:
   

Seam Marking:I carefully marked seams in less visible areas, ensuring optimal UV layout for texturing.

Unwrapping:Using Blender's UV Editor, I unwrapped the model to create an efficient UV layout, maximizing texture space and minimizing distortion.

1. Baking Maps
   

Normals and Ambient Occlusion:I exported the low-poly model and high-poly model to Substance Painter, where I baked normal maps and ambient occlusion maps. This step adds depth and detail to the textures while keeping the low-poly model optimized.

1. Texturing in Substance Painter
   

Base Materials:In Substance Painter, I started by applying base materials for different parts of the caliper, such as metal for the main body and rubber for any seals.

Layering and Detailing:I utilized layers to add wear and tear, scratches, and dirt. Using the smart materials and masks, I created realistic textures by simulating the effects of wear over time.

Custom Textures:I painted custom details and effects, such as paint chips or surface imperfections, to enhance the realism of the caliper.
