@mittens that is certainly an impressive image. Would that render cost be fixed / linear in the number of lights? Or is there any sensitivity to the number of other renderable items in the scene?

it's deferred lighting, so theoretically the render cost is fixed until you start having lights that affect a wide number of the same pixels in the scene
And if it's a volumetric light, then it's linear
So, I'm running into an error running the interface (pretty immediately after launch):
Program: E:\hifi\build\interface\Debug\Qt5Cored.dll
Module: 5.6.2
File: global\qglobal.cpp
Line: 3018

ASSERT: "_desktop" in file E:\hifi\libraries\ui\src\OffscreenUi.cpp, line 517

it also doesn't like me ignoring the error, apparently. (everything is building fine in Debug & Release)

I don't think the installer gave me the option of 5.6.1; just "5.6"
Zach Fox
@zfox23
Mar 20 2017 17:44
yeah - you have to download the offline installer
Trent Polack
@mittens
Mar 20 2017 17:44

it's big (850MB), but the only way to install the required 5.6.1

Mar 20 2017 17:45
odd that it's not there
Zach Fox
@zfox23
Mar 20 2017 17:45
yeah.
you have to dig to find the offline installers - then you'll find it in QT's file tree.

anyone here know about Quat functions? I have a question about them on the worklist job: https://worklist.net/21223

Yup
Hmmmm, I was suspicious, so I just checked the functions myself, there's no problems with them.

This job is just renaming toFront as toForward. Is that already done? Perhaps the bug just didn't get closed.

Ohhhhhh, that's a complain about naming. Gotcha.
