Description of the Issue
When importing an OBJ model in Adobe Dimension 4.1 on macOS, texture references fail to load if the .mtl file uses Windows-style backslash \ separators (e.g., map_Kd textures\my_diffuse.jpg). Editing the MTL file to use forward slashes (/) instead (map_Kd textures/my_diffuse.jpg) resolves the issue, indicating Dimension 4.1 is not properly handling backslash-based paths on macOS.
Steps to Reproduce
1. On macOS, prepare an OBJ file with a corresponding MTL file containing backslash-based texture paths, for example:
map_Kd textures\building_diffuse.jpg
2. Import or open the OBJ in Adobe Dimension 4.1.
3. Observe that the textures do not load, resulting in a missing or default material.
4. Open the MTL file in a text editor and replace backslashes with forward slashes:
map_Kd textures/building_diffuse.jpg
5. Re-import the OBJ and notice that the textures now load correctly.
Expected Behavior
Adobe Dimension 4.1 should recognize and properly parse both backslashes (\) and forward slashes (/) in MTL texture paths, ensuring out-of-the-box compatibility with MTL files exported from Windows-based pipelines.
Actual Behavior
Dimension fails to load textures when paths are written with backslashes, forcing users to manually edit MTL files to replace \ with / in order to see materials and textures correctly in the scene.
System Configuration
• OS: macOS (various versions, including the latest)
• Application: Adobe Dimension 4.1
Request
• Please add support for Windows-style backslash paths in .mtl files in Adobe Dimension 4.1 (and future updates).
• This will prevent disruptions for artists working cross-platform and ensure Dimension seamlessly recognizes texture references regardless of path separator style.
Thank you for addressing this issue and helping improve the cross-platform workflow in Adobe Dimension!
