Kelp animations are not aligned correctly for double-sided model, causing "double stem" effect
The kelp top animations are not configured properly for the new double-sided model. This causes the stem to appear twice at some points in the animation, and disappear entirely at other points.
The kelp plant is affected similarly, due to the kelp_a/b/c/d system.
Bedrock Edition
Java Edition
To Fix
Use the same [ 0, 1, ... 18, 19 ] frame array for all kelp animations. With the new double-sided model, there is no reason to offset the animation frames of each face.
Affected atlas tile animations:
- kelp_b
- kelp_c
- kelp_d
- kelp_top_bulb
These atlas tiles should be changed to match the frames array of kelp_a and kelp_top.
Here are the fixed animation arrays:
You can test this fix using this sample pack. This sample pack also fixes the frametime and frame blending issues of kelp: kelp_animation_fix.mcpack
Expected Result
The kelp top and plant animations are seamless, like Java Edition.
Observed Result
Kelp animations are not configured properly for the new double-sided model, causing alignment issues.
Created Issue:
Kelp top cross model animations are not aligned correctly, causing "double stem" effect
The kelp top cross model planes are not configured properly for their animation. This causes the stem to appear twice at some points in the animation, and disappear entirely at other points.
The kelp plant model does not have this issue, only the top.
