Hello,

I'm building a generator for folding boxes, which I want to use in Unreal. In the HDA I use a Timeshift-Node to freeze the UV in the unfolded state before I apply the folding animation. That works great in Houdini but doesn't seem to transfer to Unreal.

Any Idea for an alternative way to create freezed UV and use them in Unreal or did I miss an attribute, or...?

Thanks in advance for any help!

Hello toadstorm,

wow, thanks for your reply and for the example file.. It works the way it is made in cavalry.
I also have another question. Maybe you have an advice here, too.
In cavalry there is another effect in the String Manipulator which I like very much. It is Text Shuffle meaning the order of the letters in a word is mixed up. As far as I understand Houdini that would simply mean to rearrange the Px and rest0 and rest1 values of the letters of a Font or MOPS Typography, without touching the rest.
I still didn't find a way to edit the data I see in the spreadsheet to achieve that. I've tried several nodes like sort, transform pieces, attribute nodes and so on in combination. I partially went into the right direction but I'm still not where I'd like to be.
Don't know, maybe I'm simply confused by the different attributes.
Do you have a hint here, too?

Greetings

Hello,

I've played around with Cavalry2D(https://cavalry.scenegroup.co) and one thing I like there is the "Transition String Maniplulator". This lets you shift the characters of a text into different characters. So you can transition from one text into another by switching the words letter by letter. You can control this effect with a slider.
This feature is available in the free version of cavalry too, but If you want to use advanced features (dynamics, etc.) to enhance the text animation you have to pay.
Since I already have a Houdini Indie License and anyways wanted to learn to script, I thought it would be great, if I could achieve the same Transition-Effect in Houdini. So I could save the money for the pro-License of Cavalry2D and also would dive deeper into Houdini.

Does anyone have an idea, how I could achieve that? As far as I understand, it would require me to script in the text field of the Font SOP/Mops Typography. There I would have to display the result of a script which swaps the words of my text letter by letter. I think this would require me to handle with a string array, maybe in a seperate node created with python?
I'm not a total beginner in programming, meaning I've had a JAVA-Course during my studies. But I have never developed in my job. The basic concepts I'm more or less familiar with, like classes, methods and variables.

Just as I said, it would be great, if someone had a hint or knows a tutorial or maybe even a finished solution for my question.
