Frameblending flipbook textures. Problem.

[sjuskadur]

Hey guys! I am having a frustrating issue I cant seem to figurehttp://amplify.pt/forum/viewforum.php?f=23 out. I am making a material with a 4x4 flipbook, and instead of jumping between frames, I am trying to set it up so it lerps between them. To do that I have set up 2 flipbooks with the same material that are out of phase and then I am using a cosine to lerp smoothly between the frames.

Accordying to my calculations, this should be working, but for some reason the shift between frames falls out of phase after a few seconds, and I cant figure out why. (you can see it working for a little bit then it wonks out)
Can any of you quickly see what is wrong?! or am I misunderstanding how the speed node in the flipbook works?

Essentially I am trying to make a super simplified version of this: http://www.klemenlozar.com/frame-blending-with-motion-vectors/

Thanks!

Hello, thank you for getting in touch!

It can be a bit tricky to get the timings down for the type of effect you're trying to create, I would suggest creating the logic for the timer you intend to use with the Flipbook node in a C# script for better control over the animation.

Nevertheless, the following modification to your setup seems to produce good results:

Thank you so much! I ended up figuring this out 10 mins ago.
Since I am an artist I definitely dont have the knowledge to do this in code X)

but here is what I ended up making along with the demo result.

I am currently turning this into a material function. I am making very slow space effects that need high resolution, so this will allow me to have 4x4 spritesheets that slowly fade between frames with some other effects on top.

No problem, glad to be of assistance!
