Implementing a custom "Run" Animation

Help and Feedback Scripting Support
#1

I’ve been trying to implement a custom “run” animation using robloxs custom animation script. Everything works well until I change the walkspeed to a certain number where the “weights” of the animations seem to collide with each other making it look very weird?

Normal WalkSpeed: 16, bugs at 9 walkspeed and returns to normal at around 7

I have mainly just messed with this part of the Animation script to fix it but haven’t been able to find a solution

local function setRunSpeed(speed)		
	local normalizedWalkSpeed = 0.5 -- established empirically using current `913402848` walk animation
	local normalizedRunSpeed  = 1
	local runSpeed = rootMotionCompensation(speed)	
	
	local walkAnimationWeight = smallButNotZero
	local runAnimationWeight = smallButNotZero
	local walkAnimationTimewarp = runSpeed/normalizedWalkSpeed
	local runAnimationTimerwarp = runSpeed/normalizedRunSpeed
	
	if runSpeed <= normalizedWalkSpeed then
		walkAnimationWeight = 1
	elseif runSpeed < normalizedRunSpeed then
		local fadeInRun = (runSpeed - normalizedWalkSpeed)/(normalizedRunSpeed - normalizedWalkSpeed)
		walkAnimationWeight = 1 - fadeInRun
		runAnimationWeight  = fadeInRun
		walkAnimationTimewarp = 1
		runAnimationTimerwarp = 1
	else
		runAnimationWeight = 1
	end
	currentAnimTrack:AdjustWeight(walkAnimationWeight)
	runAnimTrack:AdjustWeight(runAnimationWeight)
	currentAnimTrack:AdjustSpeed(walkAnimationTimewarp)
	runAnimTrack:AdjustSpeed(runAnimationTimerwarp)
end

Any Ideas?
