Constant zooming in and out while texture painting, only to resize your brush every single time, is a massive time sink. Because Blender’s default brush system relies on screen pixels, zooming out leaves you with giant brush strokes, while zooming in makes them microscopic.

Fixed Brush Size for Texture Paint solves this completely by locking your brush size to real-world 3D space (meters/units) rather than screen pixels.



🌟 Key Features
Seamless & Intelligent Zoom: No matter how close or far you zoom from your model, the actual size of the brush stroke on the surface remains perfectly consistent.

🔸Dynamic Surface Detection (Ray-Cast): The add-on dynamically calculates the brush's distance from the model's surface, instantly updating the pixel ratio on the fly.

🔸"Set and Forget" Convenience: It runs entirely automatically and silently in the background. No complex configurations needed—just focus on your creativity.

🔸Performance-Friendly: Thanks to its highly optimized code structure, it won't cause lag or stuttering, even in complex scenes or with high-resolution textures.



❓ Why Do You Need This Add-on?
If you are working on character design, environment modeling, or detailed hand-painted textures, brush consistency across the entire model is vital. With this add-on:

1 - You won't get mismatched brush thicknesses across seams or areas with varying resolution feels.

2 -  You will stop wasting time constantly pressing F to eyeball the correct brush size after every camera movement.

3 - You can seamlessly transition from detailing a character's face up close to painting their armor from a distance, maintaining the exact same brush scale in one smooth motion. For

Professional Texture Artists: A small but powerful workflow booster that upgrades Blender's native painting tools to feel as consistent and scalable as advanced, industry-standard texturing software.



Limitations:
🔹The maximum distance you can move away from your object is 200 meters. Beyond this distance, you will reach the brush's limits, and its accuracy will gradually begin to deteriorate. Therefore, make sure your objects are not too large.
