Substance Painter Tools - Multi Washer/Bolts/Screws

Its a Multi-Material which allows to scatter different types of steel bolts, screws, nuts with different heads with multiple head types such as hex, mushroom, flat, and torque mushroom. Its a full PBR stencil I designed and developed to significantly speed up my own Substance Painter workflows and avoid monster-layer-stacks.

Key Features:
- 20 Bolt/Head Variations: Includes optional washers, adjustable scale, and independent color controls for both washers and heads.
- Scatter Methods: Compatible with both Spline and Brush tools. A quick demonstration is included in the video preview.
- Dynamic Controls: When scattered via spline/path (with Path selected), all parameters remain editable. Note: When applied as a stamp across the full texture set, parameter adjustments are disabled.
- Material Application: When used in UV/2D view, ensure Channel Mapping > Mask is set to Opacity. This is a standard Substance Painter requirement to avoid affecting the entire square canvas.
- Brush Hardness: Adjust the Brush Hardness setting to control transition sharpness during application.
- to get bespoken ALPHA when using the PATH tool - remove the default one - this way you can bypass the default ALPHA by unlocking extra options in the brush’s CHANNELS MAPPING. Now assign custom opacity behavior to your tools simply by selecting OPACITY under MASK.
- contains SBSAR file which can be used in many way as well as drag-and-drop SPPR file PATH preset file.

Please bear in mind:
- Height Displacement is dependent on mesh density. Low-poly meshes will not displace; medium-density meshes may stretch. For such cases, consider relying on Normal Maps and Parallax Shader Displacement instead.
- Substance Painter duplicates both normal and height maps during use. If your final model does not utilize displacement shaders, it's recommended to disable the height map to avoid redundancy.

📦 File Format & Availability
- Packaged as an SBSAR file - simply drag and drop into Substance Painter.
- The oldest Substance Painter version I tested it was the 2023 and it worked fine there. It certainly works great on 2025
- With the 1.1 update I added 'SPPR' file - which is a PATH-PRESET. When dragged into Painter and double clicked, activates the PATH tool with proper setting. Tested and works in Substance Painter 2023 ver: 9.1.2 and 2025 ver: 11.0.3.
While SBSAR seems to be fine, for some reason the SPPR crashes in 2023 - 9.1.1 and earlier Substance Painter versions during the import.

1.2 release (2026Feb)- change list:

- Improved SBAR opacity handling:
All material channels in the SBAR now include opacity by default. There’s no need to manually enable it anymore - when the material is dragged in to the scene, every channel automatically carries opacity. In the channel mapping, this is visible as 'channels_alpha'

- Updated SPPR PATH tool for Substance 3D Painter:
The tool has been updated to use the improved SBAR file.
(No behavioural changes -  the previous version already passed opacity correctly to the Mask input)

Compatibility
Tested in Substance 3D Painter 2023 (9.1.2) and 2025 (11.1.3). Importing the tool into older Painter versions may cause crashes or error messages.

----------------------------------------------------------------

1.1 release - (2025Oct) change list:
- added SPPR Path Preset file - tested in version 2023 - 9.1.2 as well as 2025 - 11.1.3 - crashes Painter when being imported to older versions
- fixed typo in SBSAR file and extended its 'description'. Now it appears as 'gb-MultiWasherBolts-1k' when inported into Painter the library
