it bacl

When I start a new project and create the nodes they work fine but then after a while working when I go to adjust the smoke object, there is no red box with handles…

Please help, thank you!

Make sure to have the handle tool selected, and, select the smoke object in Dops

That is the behavior I would expect but this has been happening for quite a few versions recently.

I just started a new project and the handles won't show right off the bat with the smoke object selected while using the handle tool.

I think I figured it out.

I use a dual screen custom desktop and I just tried switching to another preset like animation and the handles came back. Then when I switched back to my custom desktop the handles remained.

It must be a display bug.

nice! it's worth logging the bug, via the support menu above. Houdini has had quite a few problems with dual screens and the bugs get fixed in the long term.
