Hi!

I was making a simple asset that converts feets and inches to meters. I'm getting the result as a detail attribute. How can I get that value to be displayed inside the parameters panel?

It's usually done with a Label parameter, and setting it with

`detail(path,attrib,index)`

I'm not entirely sure either what it is you want to achieve

, but following my guess... that label parameter, label 1 entry has to be between tilde characters `detail("../Measure_converter",etc...)` for it work. otherwise it won't display correctly.

Ah, I forgot about that!

Now I'm getting the label to show up but the value is always "0" even if my detail value is 0.73152. Not sure what I'm doing wrong...

have you got this to work? I have the same problem.

Not sure about your context, and I’m on the move. If you are using Python maybe try .eval() after your command.

Maybe share a file with this case?

Hey SWest,

thank you for your help. I don't think it's python. Take a look at the file. I want to display the value of rand in the display parameter called Rand_is: But it always shows 0.
My end goal is to display a color in the hda interface randomly created by the hda. It would be beneficial if you have an idea of how to do that.

Cheers

Okay, now I’m outside with no chance to test anything. However, basically you seem to want to ”read” another parameter. With Python this would be setting a keyframe to a parameter telling it to update itself to some other parm. However, since you are not using Python you will need to get the expression to do something similar. A random color is just three float values, and I think you find the correct data type in the editor ”Edit Parameter Interface” (gear icon). When I have opportunity to take a look I will, otherwise I think there are a lot of seasoned Houdini users around here who will answer first. Cheers!

Hey SWest,

thank you for your help! Unfortunately, this is not what I'm looking for. In your setup, the random number is generated inside the hda interface and not by nodes contained in the hda. this is important to me, as I want a multiparm setup in the end. the data should come from the node network to the interface. like I tried in my example with the rand value.

It works if you set the node path correctly. e.g. detail("/obj/geo1/subnet1/make_rand","rand",0) or probably easier to just set it relative: detail("./make_rand", "rand", 0)
