opacity blending

[andrewsilver1997]

Theoretically the opacity is set to be no larger than 1. But I accidentally set the opacity to be larger than 1 and I still get some good visualization from yt. I guess yt has its opacity blending mechanism, could you tell me more details?

Thank you in advance

Hi @andrewsilver1997 , apologies for the slow reply. Could you add a bit of detail to your question? are you asking about opacity during volume rendering? Some sample code of how you're setting opacity would be helpful. I'd guess that an opacity of >1 would simply be fixed to opacity = 1, but would have to know more about what part of yt's API you're using to know for sure.
