Optimized Mangrove Propagule Models

all models associated with mangrove propagules range from moderately to grossly unoptimized. this pack aims to fix all of these issues, while keeping the final model visually identical.

list of changes

• starting with the worst offender, the hanging state for propagules. these models are comically unoptimized, due to not removing faces that are impossible to actually see. the hyperlinked bug report contains a fixed pack for these, but this pack goes further. this pack changes the texture so that all previously seperate elements are joined together.
• the ground sapling form is alot more simple of an unoptimization. it uses two crosses instead of one, so that it can have the stem be in the middle (causing a mixel, which I am fine with but others may disagree). this pack fixes this by using the standard cross model, and using a 32x32 texture for the block instead. the item form is unaffected.
• the potted form is unoptimized because it's based on the vanilla flower pot, which is similarly extremely unoptimized. this pack uses an all new model (which uses the vanilla texture!) which has a much better face count. it also uses the 32x32 texture mentioned previously.
