Hey @Hola65567,
Is that different from what was described above? Is your loop drastically different from your regular jump cycle? Your loop in theory should be the peak of your jump so should follow through smoothly if you land right after and be nearly non existent. I feel like we may be missing come context if the above solution is not working for you.
Would you mind sharing your jump animations, as I am having a hard time seeing why you would need to transition directly into your land from jump at the moment or how you are wanting to set it up. The reason being is that you would need to pre calculate your jump before you even jump if you want to only run through the loop phase when a certain height requirement is going to be met.
