I think that links wrong. Can you post it again?

Just about to call it quits for tonight.

Here's the first sample image. Nothing to impressive as it only has one light. At this stage I can't create more copies of the studio light (some Python code isn't working). So I have to unlock to edit parameters. Anyway tomorrow I'll have it fixed and will do something better.

Ok, I'm stuck again.

The xStudioLight asset has a multiparam block that has the same parameters copied from another asset called xStudioGobo. Each block of parameters is going to represent an instance of a xStudioGobo object inside an editable subnetwork of xStudioLight. So there is a button called "Update Network" that will create xStudioGobo nodes, and then map those parameters to the parameters in the xStudioLight.

So if I have 3 parameter blocks on xStudioLight, then 3 xStudioGobo nodes will be created. Each parameter in xStudioGobo will have an expression assigned to it, something like, ch("../../../../paramname")

Here's the Python code that is called by the button.

#
# Updates the inner network, creating xStudioGobo nodes
#
def updateGobo(node):
 up = '../../../../'
 net = hou.node('comp/gobo_network/do_not_edit')
 count = node.evalParm('goboFolder')
 for x in range(count):
 gobo = net.createNode('xstudiogobo')
 # Reverse map parameters from the xStudioGobo node to
 # parameters in the multiparam list on xStudioLight
 map = gobo.parms()
 for m in map:
 print m.name()
 m.setExpression('ch("'+up+m.name()+str(x+1)+'")')

It works ok for the regular parameters, but there is a Color Ramp parameter on xStudioGobo and it's not working right. While the two default points have expressions set, when I add more points on xStudioLight those points aren't added to xStudioGobo. I think my problem is that I'm not really linking the parameters together, but just simply setting an expression.

Can anyone tell me how to link two parameters together in Python?

Thanks

EDIT: Maybe what I'll do is add a callback to the color ramp on the xStudioLight, and then update the xStudioGobo with the number of color points when they change. That seems to be the only part that's not working.

That is cool, thanks. I'll use that for the next set of samples.

How do you add a node to a subnet and connect the first subnet input to the input of the new node? (in Python)

I tried hou.Node.createNode, hou.Node.createInputNode and hou.Node.createOutputNode but only createNode added the new child inside the subnet.

EDIT: It took some figuring out in the Python Shell, but I got it working.

subnetnode.node("child").setInput(0,subnetnode.indirectInputs()[0])

It would be cool to have a setup with reflector cards like this maybe: http://polygonspixel...ost/16524379750

That beer can is awesome. xStudio will include xStudioReflector but I'm not completely sure what it's feature set should be. I have one week left to finish in time for the release date. So I don't know how many samples scenes there will be, but I definitely will add some to the next release.

I've attached a screen grab of a xStudioReflector. Any feature requests or ideas would be great. There are a few options to customize the material, but I think it's missing the option to make the material glow without illuminating the scene.

Hi,

Here's a teaser image of xStudio that I made tonight. Still needs a lot of work to get ready, but it's coming along.

A few examples of some procedural light sources using xStudio. I think I'm getting a good handle of what features it needs. Made a list tonight of some changes that will make it easier to use.
