It should be possible for sure. But I'm not at pc right now.
I guess you may use $F in squarebracket before .png
To write sequence. Im not sure test it out.

Have you tried this
I wrote out textures using this. But havnlent tried to write slapcomp. It should work. But let me know if this works.
Cheers

Houdini Indie and Apprentice » RECEPIE - Unable to store a recepie with `karmalensmaterial`

Thanks for reply.
Yeah I can understand that it is just an Edit material Properties LOP with some predefined parameters.
But I just want to save it along with other Nodes. (Kind of a turn table template which includes this node with lens parameters).
I don't really want to host the recepie (im guessing the anchor node is what you mean here)
using that particular node. But even if I host it on any other node it still doesn't work.
Basically in short Edit material Properties LOP which has the lens Properties in it is not working when trying to save it in a recepie.
Hope that was clear. Sorry if I'm adding more confusion.

I not able to save the recepie and load it back if I try to save a recepie which contains `karma lens material` LOP,
However if I try to save a new `edit material properties` with defaults it works fine.
Is it just me or everone is having trouble with this?

I use COPs a lot even with the current bugs the thing I miss the most is a decent rotoshape vector node, please tell me that I am going to have that on copernicus!🙏
I wish the same as well. But chances are less it seems. In the keynote they showed shapes were built using sdfs. I think it will be something like hacking curves sop to make rotoshape?. But this is just my guess, who knows what is coming.

What a wonderfull update.
My most favorite features.
1. COPs 2.0
2. Receipes
Cops seems insanely improved.
I can't wait to get hands dirty.

I just opened your hip file and had a look.
It looks like the exec() function is doing something here.
If you run the same script from the python source editor it sets the expression properly.
I dont have a solution for this case, but what i would do is make the subnet into hda and call the script from hda module so i can avoid the exec function.
Im too interested to know why this doesnt work when calling a script with exec() and how to fix.
Waiting for the experts!

I think that is not straight forward inside of vops.
Two ideas i have.
1. you may use vex snippet to
iterate through all points and find maximum value. (You could also use for loop in vops)
2. You may store that value to a list/array, sort the array and get the last or first index.
Example here. You will Need to alter it to use inside vops.

I know this is pretty old post, still posting my method here so it may help people in future.
Python has this function called exec(string) which executes given string as a python code.
So you can simply do these steps
It will get the string from multiline string parameter and runs it as python code.
obviously you can point this to parm from any node and run from that node.
this could be very handy when you want to store python codes in hip file itself. very much portable!

- create any node
- gear icon > edit parameter interface > create a multine string parm > optionally set it to python language for syntax highlight
- create a button > add a this in callback
exec(hou.pwd().parm("your_string_parameter").eval())

you can use an attribute (lets say `@twist_mask`) to control the twist, this attribute is a multiplier, so you can manipulate it as much you want such as re-mapping that using curveu attribute and use that mask to drive the twist.

Hi all, Ive read multiple forums regarding this but still not able to make it work.
Im trying to modify a custom `multiline string parm`
I want to change the language of it through python, say i have a dropdown to choose formatting whether python or vex.
here is what i did so far, I found the way to do this is using the .setTag() function to set {"editorlang : "python"}
i can see the tags are modified by printing my parmTemplateGroup but i couldnt see the change in the node.
Im not sure what im doing wrong, can someone help please?

I am afraid having too many controls would make the hda confusing and hard to use but nevertheless its good to know how to do this.
I just made a simplest example for this without using python. It might give you some insights on how you could go about it.
Since it is dynamically updating the parms each time the number of rooms increase or decrease, which ever parms you already setup might get destroyed. Hmm not really ideal, but here you go.

Matt's solution is great and to add to that,
I will use this button here to visualize the gnomon, i havent realized that button exists for a long time when i started with Houdini. so sharing for someone who might not know this.
