Wow! Thanks a lot, it works perfectly! One last thing: Does it have a way to select one of the entries like in this example?

Hi fellow magicians,
I was wondering: how do you create radio button parameters in Houdini? I mean, the radio button folder is straightforward but impossible to find for list. Does anyone know how to achieve this?

Hi all, I'm happy to introduce my latest HDA: Camera Info Overlay Tool, designed to provide shot information directly on your camera view.
Key Features
•Data: Put the basic information about your project, like the name, the work item, and its version.
•Layout: Choose what data to show and customize where to put them.
•Notes: Type additional comments and todos about the sequence.
•References: Put up to two thumbnails of your references in the corner.
•Font & Colors: Choose your favorite font and change the color of the text, notes, bars, and composition frames to personalize your overlay.
Feel free to give feedback to enhance the tool!

Hey Grendizer, thanks a lot for testing the tool!
Unfortunately, the tool is not in Labs.
I fixed some issues in the next version of the tool, you can find it here:
https://drive.google.com/drive/folders/1oNem-N-K4DjjsfXFuZ2bNBFP3CbrqkTb?usp=sharing [drive.google.com]
Concerning your questions:
- The tool doesn't have textures,
- The material library is available with the search icon in the shaders section,
However, you can assign your own shaders to the geometry.
- The camera from the tool is not made for use, you just have to plug the tool into your actual camera.
You can refer to this video: https://youtu.be/cEmrvDDTQPw [youtu.be]
Thanks again for your feedback! Give it a try and tell me if it's working properly!

Ruthie
Hi! I am trying to use your HDA but had a question. The realisting option in the parameters makes everything dissapears, maybe because the file is missing, so are the textures and this file somewhere?
Or its something I have to click on and I missed it?
Thank you!
Hi Ruthie! Thanks for your feedback!
You were right, there was a missing reference.
Here is the updated version, feel free to give it a try!

• Transform:
- Compact / Vertical: Position left / right, rotation and scale
- Realistic: Transform / Rotation / Scale
• Color Chart: Optional Color chart
• Backplate
- Procedural Backplate
- Created only on-camera frustum, avoiding blocking light.
- Backplate from any angle
• Shading:
- Materials assignment for the asset (balls, chart, stand, and backplate)

Description
Detect the frame at which attribute reaches given conditions. Then create and store attributes on points:
• @startframe attribute corresponding to the frame the change occurs.
• @triggered attribute corresponding to based on point's state.
If @startframe's value match current frame, @triggered is set to 1.
• @id attribute sorted by point's start frame.
• Node Type: SOP.
Features
• Condition to reach to trigger computation
• Visualizer for @startframe, @triggered and @id attribute.
• Dynamic label that return simulation data (@startframe of the first and last point to be computed).
Use cases
• Synchronize animations or simulations(drive switches, trigger simulations one after another,...).
• Get additional data from animation or simulation (@startframe can be used to determine age, life, contamination speed, ...)
Node Features
Some Examples

This was a 16-week challenge where we had to add FX to the provided assets. The design brief was wide open, allowing us to explore all sorts of FXdomains to tell the story (characters and camera animation provided).
It was great to be part of this challenge, and I encourage you to watch all the amazing entries that the other entrants delivered!
Yet the adventure barely begins. With all the knowledge I'll take away, I can't wait to work on future projects. Huge thanks to Rebelway, the Rookies, and their sponsors to make the challenge possible!

Solaris and Karma » Karma AOV and LPE Tags
- JohnFanny

Hello team!
Do you know if there is a way to export AOV for each light in Karma (as Mantra can do)?
In short, how isolate contributions from individual lights using the LPE tags.
I recently seen that LPE tag properties are for mantra only and there's currently no way to specify tags for Karma at the moment.
But is this feature planned for the next releases? Or is there is a workaround for it at the time?
