THANKS!

bit of process to accesss textures: In Blender 3.5, the process for ensuring textures are included with an FBX file for use in Unity may not explicitly include an "Embed Textures" option as in previous versions. Instead, the workflow focuses on ensuring textures are properly linked and then manually copying those texture files to your Unity project. Here's how you can manage this with newer versions of Blender: Preparing Textures for Export Ensure Textures Are Correctly Linked: Before exporting your FBX file, make sure all textures are correctly applied to your materials in Blender. This means ensuring that each material that needs a texture has it correctly assigned within the Shader Editor. Pack or Unpack Textures: While newer Blender versions might not have a straightforward "Embed Textures" option for FBX files, you can still choose to pack your textures into the Blender file for organization. If they are already packed (as in your case), you will unpack them to manually manage them for Unity. To unpack, go to File -> External Data -> Unpack All Into Files. Choose a directory option that suits you. Exporting FBX without Embedded Textures Export the FBX File: When exporting the FBX: Go to File -> Export -> FBX (.fbx). In the export settings, there isn’t a direct option to embed textures as before. Instead, ensure that in the Path Mode option (under the Armature tab), you select Auto or Copy if available. However, understand that this does not embed textures but prepares the file paths for external use. Managing Textures for Unity Manually Copy Textures: After exporting your FBX, manually copy the textures you previously unpacked (or already had) into your Unity project’s Assets folder. This step is crucial as Unity does not automatically import external textures unless they are placed in the project’s asset directory. Assign Textures in Unity: Once you've imported your FBX model and the textures into Unity, you might need to manually assign these textures to the materials in Unity, especially if they weren't automatically linked. Locate the materials in the Unity Editor that are associated with your imported FBX model. For each material, find the texture slots (like Albedo) in the Inspector and drag the corresponding texture from your project assets to the slot. This approach ensures that all your textures are included with your Unity project and properly applied to your models, albeit with a few manual steps for linking textures to materials in Unity. Unity's material system is flexible but requires that textures be present in the project's asset directory for them to be assigned to materials.
