When I animate the line, all the points are flashing.
After sweep, the uv is also flashing, and the copied object is also flashing after copytopoint.
Please tell me how to solve this flickering problem, thank you very much for your help!

Technical Discussion » Houdini Indie - License login connection timed out

Hello
When I opened Houdini, I was prompted with "A license could not be found to run this application." After that, I installed a login-based license through Houdini Launcher, but I couldn't log in and kept getting prompted that the connection had timed out.
When opening the license server through the web, it prompts that hserver is not running, but hserver is started in the manager.
This problem has been bothering me for three days. I am currently in the middle of my work, but I cannot open Houdini at all. Please help me figure out what is wrong. Thank you very much!

Hey, details() expression is for reading intrinsic values, detail("../set_seed", "seed_detail", 0) without "`" work for me. The "grave accent" characters are only needed if, for example the input field is a string and you want to pass an expression. In your case, both the retruned value of the expression as well as the input are integers.
I was too careless, just delete "``" and it will be fine. Thank you for your help!

I created the seed variable so that it +1 every 10 frames.
Then convert to detail via vex.
Everything is normal up to this point, but when I reference the seed variable, an error occurs.
I tried two methods, but neither can be quoted. Why is this?
thank you very much for your help.

You can use also use a merge node inside the for-loop. If you set the loop up in feedback mode the merge will add a font output in each iteration.
Thanks for the idea, I'll try it out.

tamteHenDaShenghere is some info on spare inputs https://www.sidefx.com/docs/houdini/model/compile.html#spare [www.sidefx.com]
It turns out that "Spare Input" is a custom parameter interface, and its parameter type directly affects the final effect. This is very new knowledge to me. I will study it carefully and I think it will be used in other places.
they are susally used within compiled blocks as that has many restrictions, but they are useful overall to refer to other nodes without having to type the path to the node in every expression
I tried to perform certain processing on the string through vex (limiting the number of digits after the decimal point), but introducing new variables in the font node did not work.
I think it's something outside of my knowledge. I guess the problem is with the new variables because they don't appear in the spreadsheet when the font node is selected.

You can also do this without a for loop network using some VEX:string pos [ ] = { }; int count = npoints ( 0 ); for ( int i = 0; i < count; ++i ) { vector p = point ( 0, "P", i ); append ( pos, sprintf ( "%s", p.y ) ); } s@pos = join ( pos, "\n" );
Then read the string attribute from the Font SOP:`details(-1, "pos")`
This is also very new knowledge to me. Thank you for your help, it gives me more choices. I will study this method carefully!

something like this
This is the first time I know how to use font node -> Spare Input. Thank you very much for your help!
I hurriedly replied after seeing the effect. I only discovered the problem when I tried it myself (it's not a problem with tamte's answer, it's my own problem).

There is a straight line and I can get the position information of each point through vex.
I want to put the position (string) of each point at the corresponding position through copytopints, but I don’t know how to get this position information in the font node. Do you have any good ideas?
I can get position information in font node with only one point,
There is nothing you can do after the number of points increases, and the font node only has an output port and cannot be nested in a loop.
Thank you for your help!

I also encountered the same problem. I wanted to export point cloud files in Houdini to Touchdesigner, but "xyz_pointcloud_exporter" could not fulfill this requirement.
Finally. I exported the .ply file through "Rop Geometry Output" and it worked smoothly.

巴巴杰HenDaShengI'm using your file, there is no modification other than what is in the sreen shot.
Thanks a lot for your help, can I have a look at your modified houdini file, I'm very new to Motion Fx.
Just bring up your motionfx window and make sure the object2/3 nodes have there flags set(blue)- so it shows up in your graph.
I did it! Thanks for your patience, and your help is greatly appreciated!

巴巴杰HenDaShengManually in graph or directly with parameter.
Can you explain in detail how to manually modify it(I found that clicking on the curve in the Motion FX view does nothing)?

Thanks, I tried modifying the options here, but it still doesn't work.
You didn't change the start/end range of your objects.
Bring up your motionfx window and enable the objects view to see where they are established; From which ever way you decided to have them set up by.(works for me if I manually adjust the range).
That's it, great!I found the problem, the last keyframe in the graph is at 330, and the Motion FX ends at 300.

If you're going to be going back and forth between changing frame rates you have to decide whether or not you want to keep the keyframes at the same frames with the 'Keep Keys on Current Frames' option.
But you also have to go back to your chops objects and adjust the start/end range too.

if you look under the channel tabs, set the sample rate to your fps and set the channel length as long as you need it... it should fix it. look in your motion channels viewer to see what you're doing
Thanks, is this what you mean? After the modification, chopNet still fails after 300 frames. Is there something wrong with my operation?

I am doing a camera animation, transitioning to different cameras through ChopNet control, but the last camera cannot always transition to the specified position. Finally, I found that ChopNet has a 10-second limit. When the frame rate is 24, it will It will fail after 240 frames, and when the frame rate is 30, it will fail after 300 frames.
How can I extend the duration of ChopNet?
Thanks for your help!

Timeshift with frame 1 then rest sop to the first input of Hair Generate, simulated vellum geo to the third input.
This method is also very good! grateful!
