Viewport Transparency Behaviour Sept. 16, 2020, 10:34 a.m.


I've been trying higher viewport quality settings and for the most part things are looking great. I mainly seem to get odd results switching better the transparency options for things like glass.

It seems going to medium / high quality does some things like losing the reflection or weirdly showing through opaque objects like a wine bottle label for example

Just wondering if theres any knowledge about this? i have a Nvidia GTX 1080 card

Also seems similar to this question i think?: []

Many Thanks,

Thanks man! Appreciate the reply!

Should of followed up in here; i did talk to sidefx, confirmed the limitations and get this logged as an RFE for extra python functionality so we’ll see if anything comes of that

Performance Monitor / Python Workflows Oct. 15, 2019, 9:08 a.m.

Hey All,

I was dabbling with chucking out a per frame performance monitor file whilst i cache (start, cook geo, stop, save profile). Largely seems to work as expected but theres a few things i'm unsure about:

1. The performance monitor seems to be getting clogged up with all these profiles, i cant see how to purge them once saved? it sounds like
would do it but it doesnt look like you can both stop / save the stats and cancel?

2. I wanted to do this accross pre / post frame scripts but i couldnt find how you would reference the profile again if you dont have the variable set in one script like the helps example (
profile = hou.perfMon.startProfile()
). I thought there would be a kind of
way of doing this? I also tried active profile but it didnt seem to be quite right

Anyone done workflows with this and got useful tips?
