Introduction
Welcome to the handy RapidPipeline plugin for Adobe Substance 3D Painter, which enables you to import, create UVs and optimize all inside Painter.
The Revolution: Seamless Plugin
Our plugin brings seamless integration: RapidPipeline adapts to your workflow, helping you clean, optimize, and prepare models with just a few clicks.
Why is this a big deal? Because you can now:
Import 30+ CAD formats natively into Substance 3D Painter
Use RapidPipeline’s easy actions for your most common optimization tasks
Create UVs based on your workflows
In this post, we’ll focus on all three available actions:
Name | Description |
Paintable UVs per Material |
|
Paintable Single Atlas |
|
Tiling UVs |
|
The Model: Sneaker with small details
For this month’s showcase, we chose a nice sneaker model with 150k faces and aim to reduce the faces to make it production-ready for web-viewers or real-time applications.
Manually optimizing this type of model can be time-consuming and prone to mistakes, often needing multiple attempts to create the desired result. RapidPipeline offers a dependable way to automate the process while simultaneously saving costs.
Import your 3D Model
Rapid Pipeline provides a set of quick and easy tools that makes importing 3D models and CAD assets a breeze. Just click on “Select your 3D File” and choose your file. Then, you have a choice of 3 actions to choose from and then, click run to import the Model.
Paintable UVs per Material
Paintable UV's per material will create a UV Atlas for each material.
With the click of a button, the surfaces are set up for painting right away, as the UVs are non-overlapping.
Now, you can drag and drop materials and see the textures update on well-formed UVs and paint on the model to add more details.
Paintable Single Atlas
This method unpacks all UVs into one paintable atlas while merging your materials.
Tiling UVs
With this action, tri-planar UVs are generated for each material, all ready for material editing. If you are more focused on visual development and need to iterate the materials quickly, Tiling UVs might suit your workflow.
You can also manipulate the Tiling UV scale to increase or decrease the UVs tiling. 
Huge Bonus: Additional Actions to Optimize your file
To further support your workflows, all actions come with a range of optimization settings as well.
CAD Sewing Tolerance
Helps with sewing CAD surface patches before tessellation (conversion to triangles).
By default, it is set to 0.05mm. If two surfaces have a gap greater than 0.05mm, they will not be sewed.
Fix Winding Order
This automatically fixes the winding order. The winding order determines what direction the vertices are facing which in turn defines whether a face is back-facing or front-facing.
If the winding order is false, it can lead to see-through faces in wrong places.
Remove Occluded Parts
This special feature removes invisible (occluded) parts of the model. This can help reduce faces that are not visible from the outside.
Simplify with UVs
This feature optimizes your mesh to your desired face count.
Result
RapidPipeline created new clean UVs and optimized the original face count of 150k to merely 30k. The model is now production-ready and performance-friendly.
