Hi there, I'm in the process of setting up a little viewport comment hda. All it does is changing the vcomment parameter on a selected camera. This works great for static text and variables but I haven't found a clean solution for time-dependent stuff such as $F. Since the hda python module doesn't execute every frame, I'm using a script SOP inside the hda which calls the phm function that updates the text every frame. The problem is, that this results in the HDA function executing last. So when doing flipbooks for instance, the image will be rendered before the hda function executes, thus the text lags behind by one frame ($F will show "1001" on frame 1002). Part of the problem is (I think) that the string is being evaluated inside the HDA. So the actual vcomment parm on the camera will already be "1001" instead of "$F" (which would probably evaluate correctly every frame). So if I could prevent the string from evaluating on the HDA, that would probably solve the issue. I'll try the same thing with a Python SOP instead of on the HDA's python module, but in the meantime, maybe someone has a better solution for this problem.

synchronizing two mplay (flipbook) sessions
berniebernie posted a topic in General Houdini Questions
Hello Odforce Is it possible to link two mplay sessions so I can have a side by side comparison of my animations ? If I have the same frame count and get lucky pressing play it works, but it doesn't really work everytime. Thanks!
