Welcome to the Global Illumination forum

Graphics Lighting & Global Illumination

Hi! Now that Unity5 is out, we have decided to create a dedicated forum for Global Illumination and related questions.

Please check out our new documentation that has been made available online (it wasn’t part of the 5.0.0f1 download) Unity - Manual: Lighting and related pages. Let us know if you find that something isn’t covered or needs a better explanation.

We just returned from GDC and have a lot of things to follow up on, but we will try and keep an eye on the new forum as much as we can.

If you find something that doesn’t work as expected, please file a bug report so we can fix it and try and keep to one topic per thread.

I hope you will enjoy the enlightening experience :wink:

This post covers how to set up a scene for fast baking: http://blogs.unity3d.com/2015/11/05/awesome-realtime-gi-on-desktops-and-consoles/ the same tricks that makes realtime GI precompute faster will speed up baked GI.

Thank you! I think some sort of best practices for baking GI would be great, like how to tackle different scenes. Especially with regards to setting the realtime resolution since I am now pretty much in the dark.

Will the GI docs linked in the OP be included in future Unity releases? It would be quite useful to just check the engine docs offline.

4

Yes, the offline docs will be updated too.

Why is this part of the forum is dead? No unity team member is checking and answering

I think this link is broken: Unity - Manual: GI cache

Thank you for highlighting this. I have fixed this, it will be out in the next documentation build.

When will we see that in some form? (even just experimental?)

13

We are working on a preview build but I can’t provide an exact date yet.

Which version of Enlighten is Unity using?

Couldn’t find the info on the site or via a search.

15

And why doesn’t Enlighten use the GPU for baking, in effect we have tiny little (core count) CPU’s sitting next to these massive 3D Math monster GPU’s and Enlighten thrashes the little CPU?

Here is an example of good global illumination rendering accelerated on the GPU circa 2005 (GPU Gems 2 -
High-Quality Global Illumination Rendering Using Rasterization)

I did find a post on Enlighten about adding GPU acceleration in 3.04, hence the previous post on version used?

Or are there some command line parameters or settings for Enlighten that I don’t know about?

16

I believe it was upgraded to 3.02 in 5.3 and hasn’t been upgraded since then.

17

We are using the following versions:
Unity 5.3 uses Enlighten 3.02
Unity 5.4 uses Enlighten 3.03
Unity 5.5 uses Enlighten 3.03
Unity 5.6 will use Enlighten 3.06
