improvs & fixes to shot 5 (bubbles shot)
1. To taper off the bubbles, the volume source was gradually scaled down to 0, stopping the bubble emission.
2. To fix the apple's acceleration, initial velocity was added to ensure consistent speed throughout.
3. During retiming, the Houdini Retime node distorted the UVs of textured assets, resulting in the apples appearing incorrect. To fix this, the "name" attribute in the retime node was replaced with a blank primitive attribute, resolving the issue.
1. Emitter Scaling down
2. Initial velocity for the apple
3. a. Retime causing UV Texture Issue
3. b. Issue Resolved

steps taken to fix the holes issue in shot 6 (splash)
a, As per David's suggestion, changed the meshing mode from Average Position to Spherical.
b. This caused several unsmooth surfaces. To smooth the surfaces, applied the filtering option in the ParticleFluidSurface node.
c, The filtering improved the surface but inadvertently removed the bubbles.
d. To preserve the bubbles, created a mask to selectively filter only the bubbles. The mask was generated using the vorticity attribute.
e. The vorticity values of the bubbles were significantly different from those of the main liquid, which allowed for effective masking.

feedback from Emily:
- Adjust the camera in shot 4 to follow the apple.
- Clean up lighting and color in shots 4 and 5.
- Address noise and sampling issues in shot 5.
- Lighten the cider color in shot 6 to match the previous look.
feedback from David:
- The apple falling behind in shot 3 can be a bit distracting.
- The apple drop in shot 5 appears accelerated toward the end.
- For shot 6, adjusting the particle fluid surface from average position to spherical could help fix the holes forming.
- The product in shot 8 may remain out of focus for too long.
feedback from Mazyar:
- There are some barn color inconsistencies across shots that could be addressed.

update on shot 5 (bubbles)
To achieve an early tapering off of the bubbles, the minimum air region voxels were keyframed to increase over time, preventing the generation of new bubbles. Despite this adjustment, the result still did not achieve the desired quality.
