To achieve a high-quality mesh setup for a front façade of a building in Spine, similar to Photoshop's distort feature, follow these steps:
Create the Mesh:
- Select the image attachment of your building façade.
- Check the "mesh" option at the bottom of the tree.
- Click "Edit Mesh" to start creating and modifying the mesh.
Define Vertices and Edges:
- Use the "Set Points" tool to draw a new polygon around your image, ensuring you cover the edges and key structural points of the façade.
- Add vertices inside the image to allow for finer control over the deformation.
- Keep the vertex count as low as possible while ensuring enough detail for smooth deformation.
Optimize the Mesh:
- Avoid placing unnecessary vertices in blank areas of the image to prevent performance issues.
- Manually adjust the vertices to create a balanced mesh that can deform smoothly.
Deformation and Subdivision:
- Use the "Modify" tool to tweak the existing polygon and ensure it deforms correctly.
- For smoother results, consider using fewer vertices initially and then subdivide the mesh if needed. Spine plans to implement subdivision features like Catmull-Clark, which can help in achieving smoother deformations.
Manual Adjustments:
- Manually adjust the mesh vertices to ensure the façade deforms as desired. This might require some trial and error to get the perfect look.
- If the mesh needs to overlap, consider duplicating parts of the mesh and adjusting weights to avoid z-fighting issues.
Linked Meshes:
- If you have multiple similar façades, use linked meshes to reuse the same mesh structure across different images, ensuring they have the same dimensions and proportions.

By following these steps, you can achieve a high-quality mesh setup for your building façade that allows for smooth and realistic deformations.
