Technical Discussion » How to set keyframe tangents from Python?

I'm scripting the creation of keyframes but even if I have two keyframes at say 1.0 that are multiple frames away from each other, the value can be a hair above 1.0 in between the keyframes because of bezier tangents on the keys so I need to make them constant type but the docs don't explain how the hou.constant is invoked from what I can tell.

I'm trying to set a channel reference by entering a string in a set operation:
transformnode = hou.node('obj/track').createNode('xform', “transform” + str(minmaxspeedindexpoint))
transformnode.parm('px').set('ch(“../font' + str(x) + ‘/tx”)’)
but it's complaining that I can't set a numerical value to a non-numerical value.

thanks. I had tried the File COP override frame range but had misunderstood the offset direction. Working now

I need to offset a set of video frames to play at a later time and can’t figure out how to do that

Technical Discussion » using file pattern TOP node with wedge?

The docs only show how to use Python node with file pattern and I'm not clear on how to use a string value derived from a file pattern TOP node with a wedge to bang out a bunch of images using different HDR environment map for env light.

ya, there needs to be a nullification of the validity of the cache if you click dirty all I think

It seems I have to delete everything generated by the TOP geo ROP node before it will output again.

thanks - I'm aware of the workflows for non-material based workflows but the new nodes have inputs and outputs like for constraints that align so I thought there was a way to get these to play nice together in a way that didn't require work like in the legacy workflows, similar to how Vellum works with piping relevant data into associated nodes. If this doesn't work like this in RBD material stuff, that's fine but I just want to know. The attached setup doesn't work to bind the connected pieces

I'm trying to see how to use the material fracturing with RBD Constraints From Curves but the docs don't show examples of how these fit together and I can't find anything on SideFX Vimeo on first glance. Anyone have a good guide on this?

I'm wondering if there is a way to do progressive Booleans on an object with the for loop so that the following Boolean ops use the output from the previous one. When I set up a scene with a Boolean in a for loop, it just does it on a copy of the base object so I get duplicates.

Marty - that looks like a bug for sure but not necessarily what we're seeing here. I suggest you log a bug with The Foundry but double check that your GPU is supported with Mari.

To prove my point, here are screenshots of other Qt apps on external screen on 2014 iMac retina with Radeon R9 M295X 4GB in OS X 10.11.3.
So here is the issue we're looking for (Houdini 15):

Other Qt apps after dragging the window to the same screen as above:

It's definitely Houdini 15 only. It didn't happen in 14 either. Maya 2016 has a Core Profile mode as well and it's not occurring there either. If someone actually can point to another instance of this occurring, I'd like to hear about it.

Marty This is the first I've seen this issue and I use Nuke, Maya, Mari, Maxwell, V-Ray, Mudbox, Speedtree, Substance Painter/Designer and a ton of other Qt-based apps on OS X on external screens.
Thought it was fixed but it's not. Seems to occur when windows that are retina resolution are moved to non-retina screens.
