Texturing #

• Removed the Layer Cache setting (Layer Caching is now always on).
• Fixed a crash that could happen when removing an Input Map from a Texture Project and performing an undo.
• Fixed a crash that could happen with Vector layers when changing from Brush to Tube mode with certain combinations of brush settings.
• Fixed a problem that could prevent font previews from rendering in a Font Vector layer until you created a shape in the layer.

• Fixed a problem with normal map rendering when referencing a Material in Vector layers.
• Fixed a problem that could cause instability/random pixels with Vector Text layers.
• Fixed a regression with small Vector Profile Width values that caused a difference in behavior from 5.02.

Rendering #

• Fixed a crash that could happen when trying to adjust texture settings for a texture or material that is no longer in the scene.
• Fixed a crash that could happen when pasting a material to empty space in the Materials window.
• Fixed a crash that could happen when renaming a material with an empty string.
• Fixed a bug that caused the raytracing lighting data to be out of date when Motion Blur Preview was enabled.

Mesh #

• Fixed a crash that could happen with UDIMs and corrupt or out of range UV position values.
• Fixed a crash when exporting glTF files with vertex colors.
• Fixed a bug with the tangent space calculator that could cause a crash with bad mesh data.

Baking #

• Fixed a regression with Alpha maps where gaps would be filled in with padding.

UI & Misc #

• Added optional fields to the crash report submission window to include additional information and an email address.

5.03 Changelog (5032) #

Texturing #

• The Scatter layer type has been added, making use of the brush preset system to scatter elements over meshes. Random and Grid scattering is supported in 3D, UV, and Decal projection spaces.
• Text mode has been added to Vector layers, making it easy to write blocks of text and wrap text to vector shapes. All fonts installed at the OS level are available, and there are various options for kerning and alignment.
• Added Layer Caching, which increases performance by around 2.7x in complex projects by reducing the amount of layer compositing work.
• Removed the Fast compositing mode and Preview Resolution settings as they were no longer necessary with the improvements made with Layer Caching.
• Individual tiles can now be paused in UDIM and Multiple Texture Set mode, increasing performance and freeing up a considerable amount of memory.
• SVG files can now be imported for Vector layers in Decal Mode.
• Vector data can now be copied and pasted between layers and from certain external applications that copy SVG data to the clipboard, like Adobe Illustrator. 
• Vector shapes in groups or as children of other shapes now have an option to inherit their parent’s symmetry settings.
• Improved performance when using Brush mode in a Vector layer, especially with high brush counts (welds and similar).
• Vectors in Brush mode now flip the textures when symmetry is on so the direction is consistent on both sides.
• Fixed a problem with normal map translation that caused artifacts when using Tile Strip mode in Vector layers.
• The system for remembering which tool was last used for each layer has been simplified. It now remembers the last tool used per type, so the active tool should remain consistently selected when switching between layers and switches to a more logical choice when changing tool types.
• Brushes with dynamic size effects (like pressure sensitivity or fade) now adjust spacing proportionally to create a consistent spacing effect at smaller sizes.
• The Smudge tool no longer creates black artifacts when used in a Paint layer that is a child of another layer.
• Resolved an issue where mesh transforms were not properly accounted for with the Direction layer.
• Normal maps should now be translated correctly when using Sticker projection in a Decal layer.
• Added a Flip option to decal layers.
• Height maps exported from Texture Projects should now have the correct color space applied and be consistent with baked maps.
• Fixed an issue with Decal layers applied to meshes with rotation transforms that could cause the decal to be in the wrong position.
• Decal layers should no longer create corrupt undo states.
• Fixed a crash that could happen if a Sync Point was saved without any active maps.
• Corrected a problem with the UDIM tile detection system where the 10th tile could get incorrectly flagged as out of range.
• Fixed a crash that could happen when using the Color Picker with the Layer Settings window hidden.
• Fixed an artifact that could happen with Vector layer shapes that have hard, acute angles.
• Fixed a crash when copying and pasting settings between Texture Projects.
• Fixed a problem that could cause a blank result when merging multiple Paint layers inside a Group.
• Fixed an issue where a Texture Project could store out-of-date UVs after a mesh was reloaded, causing the bakes and Texture Project to be out of sync.

Rendering & Materials #

• IES light profiles are now supported, and various IES presets have been added to the Library.
• Physical light units are now supported for lights. Omni and Spot lights use Lumens, and Directional lights use Lux.
• Added a Distance setting to lights to make it easier to control how far lights shine or limit which objects a light interacts with.
• Multi-selection and editing is now supported for materials.
• Added a Fog Shadow Quality setting in Raster and Hybrid modes that can be configured to increase the quality of light shafts in the fog volume.
• Added a Motion Blur preview button to the Timeline window that allows you to preview the blur effect in the viewport. Note: Motion Blur must be enabled in the Camera properties.
• Added support for light scaling.
• Added support for light gels in Fog when using the Raster renderer.
• Fixed a filtering problem with transparent textures when using the raytraced Depth of Field mode.
• Fixed a crash that could happen when a template material was used to modify the default material configuration.
• Resolved a shader error when copying Material Layers between Materials.
• Fixed an issue where light could bleed through shallow walls when using Fog in the Raster renderer.
• Fixed some shadow rendering artifacts on MacOS.
• Fixed various GPU crashes.

Baking #

• Curvature bakes are now more accurate and produce fewer artifacts. Faceting from the low poly mesh’s geometry should no longer be visible, and areas near UV seams are somewhat improved.
• Added a Max Ray Distance setting to limit how far from the cage rays travel. This is useful for meshes with holes, like chain mail, as it will prevent the rays from shooting too far and hitting nearby objects.
• Fixed a pixel padding regression that caused artifacts near pixels with ray misses.
• Changing the Geometry Mode setting for one Bake Project will no longer change it for other projects in the scene.
• Cage generation now handles degenerate triangles more gracefully.
• Fixed an issue with Material ID and similar bake types that caused a small amount of noise in areas that should have been solid blocks of color.

UI, Scene & Misc. #

• 3DConnexion SpaceMouse navigation is now supported.
• Added an option to send anonymous crash report data to help the development team track down and fix problems. Please use this if you see it; we promise we’re not harvesting your data or doing anything shady.
• 38 Python fixes and additions.
• Improved font coverage for non-English characters for filenames, paths, etc. Now characters from the 50 most common languages are supported.
• Fixed various bugs relating to MacOS and multiple monitor support.
• Fixed a crash that could happen when saving objects/USD files to the library with invalid names.
• USD exports should no longer save a copy of texture resources when File References is set to Keep Paths.
• UDIM tiles are now properly exported from Texture Projects with USD files.
• The camera types should no longer reset in the Setup Workspace when loading a new scene.
