No prob! Thanks for being so responsive.

https://www.youtube.com/watch?v=AXwGVXD7qEQ [youtube.com] So far so good! Thanks!

lol Nice! Was the crash when you opened an old scene also fixed?

Yup! The old interface (no ramps) is still there until I click to reload the asset, but otherwise it's working great.

Hey Andrew,

Not sure if it's related to ramps or not, but my scene is crashing when I try to rebuild the asset in new Houdini version 14.0.403.
The old scene was created in 14.0.386.

Any thoughts?
We really need it to work stable without crashes when we switch from one Houdini version to another going forward.

Thanks a lot for your support!
Alex

Not sure if it's related to ramps or not, but my scene is crashing when I try to rebuild the asset in new Houdini version 14.0.403.
The old scene was created in 14.0.386.

Hm, just from the stack trace, I can't tell if this is related to ramps or not. I wonder if the crash could be because of parameter was added or removed. If you instantiate the asset in a fresh scene using 14.0.386, then (without modifying the asset file) load the scene again with 14.0.403, and do reload/sync. Does it crash? This might tell us if it's related to simply changing builds, or some other cause.

Is there any way to add these to a custom qt interface?

The ramp UI is created using Maya's AEmakeLargeRamp, which uses standard Maya widgets. So it's possible to embed it inside a custom Qt interface. Maya provides the MQtUtil class to find the Qt pointer and the Maya name of a Qt widget. Once you have the Maya name, you can use setParent, and run MEL commands to create widgets as usual. See the example:


Maya's documentation has more info on this:

This is just great, awong. Very helpful.

Trying the ramps. Seems like the first segment outputs NaNs. Not until I have two points on x=0 (thus removing the first segment) do I get correct evaluations. The points that queries the first segment disappears.

Also had a a crash when touching a ramp but I'll get back when I got a repro.

I can't seem to reproduce that the NaN outputs. Are you able to reproduce it on the assets posted in the earlier post here? https://www.sidefx.com/forum/topic/39349/?page=1#post-182227 [sidefx.com]

No, it was on the attribute editor.

I submitted a bug earlier with scene and hda.

Finally got around to implement this, hit some issues that someone helped me deal with:
