QuickSDFTool v1.0.1

QuickSDFTool v1.0.1 is a patch release for the stable UE 5.7.x line. It keeps the v1.0 runtime/editor asset format intact and focuses on small paint-mode fixes plus documentation cleanup.

Tested Environment

The attached Win64 binary package is built from the v1.0.1 tag with Epic Games Launcher UE 5.7.4. It replaces the earlier custom-engine package for this release. Rebuild the plugin from source if you use a source-built, licensee, custom, or otherwise different engine build.

Changes Since v1.0.0

• Changed the default mesh paint mode to Screen.
• Fixed Screen mode brush HUD/input alignment across viewport DPI and multi-display scaling differences.
• Fixed Screen mode F focus behavior so a valid brush hit can focus the brush position instead of falling back to full mesh selection focus.
• Adjusted brush focus radius estimation for Screen projection so focus distance is closer to UE modeling/sculpt workflows.
• Documented a tablet/pen-display hover limitation where lifted-pen movement may not update the brush preview before the next stroke.
• Reorganized README / README_JP into concise project entry points and moved detailed workflow, development, and roadmap content into docs.
• Added workflow screenshots and character model credit for the documentation.

Upgrade Notes

• The plugin descriptor now reports VersionName as 1.0.1.
• This release does not intentionally change public C++ APIs, property names, enum names, shortcuts, or UQuickSDFAsset saved format.
• Existing v1.0.0 assets should continue to load unchanged.
• The supported target remains UE 5.7.x. Treat UE 5.8+ as unverified until a later release explicitly adds it to the tested matrix.
• The attached Win64 binary is built with Epic Games Launcher UE 5.7.4 for Launcher UE 5.7.x projects. Rebuild from source for source-built, licensee, custom, or otherwise different engine builds.

Known Limitations

• UV layout can affect the relationship between brush size and painted area, especially on heavily stretched or uneven UV islands. Use clean UVs or the 2D UV preview for precise edits.
• On some pen displays and tablets, hover movement while the pen is lifted may not update the brush position. Confirm the brush preview before starting the next stroke.
• GPU JFA SDF generation is not enabled in the v1.0.1 user-facing generation flow.
• UE 5.8+ compatibility is intended but unverified for this release.

Verification Steps

1. Build sdfbuildEditor Win64 Development:

   Build.bat sdfbuildEditor Win64 Development -Project="C:\Users\condo\Downloads\sdfbuild\sdfbuild.uproject" -WaitMutex -NoHotReload
   

2. Enter Quick SDF mode and confirm the default paint mode is Screen.
3. In Screen mode, confirm the brush preview tracks the cursor correctly on the active display.
4. Press F while hovering a valid Screen mode brush hit and verify the viewport focuses around the brush position.
5. Confirm Select/Paint workflow, active slot overlay, default Isolate Slot behavior, and SDF generation still work as in v1.0.0.

Automation tests were not part of this patch-release verification pass.
