When you create a new publisher set...
And if you already have created a publisher set...
Now the GI is not visible in the new BIMx app. It is only available in BIMx Legacy version, which may cease to exist anytime. Should be expect the GI visibility in the new BIMx, or any other methodology applied to show better hypermodels?
The reason why GI is not in use, because on Mac it been replaced with Metal rendering system - built in into iOS.
Original GI was actually ambient occlusion (that is not really GI) and took ages to perform on large projects - because it used only one core for calculations. So even if you have the most powerful 12 cores killing machine - GI production might take all night.
The new metal shading looks different but not so bad (just don't know how it looks on Android or Windows now). Most important - it solves the problem of very long GI processing in large size files.
I would like to see more professional solution for GI in BIMx - that it would be more photo-realistic and support light sources. This is something that Interior designers really need.
