Two Ways To Make Stuff Glow...
-----------------------------------
I'm usually happy making lights etc glow using 'super-ambient', but there is an undocumented limit. The surface brightness does [b][i]not [/i][/b]increase if dialled beyond a dozen or so. This is not a problem if you have 'luminaires' with a large surface area, like ceiling-panel lights. It is a nuisance if skinny 'strip-lights', exasperating if pendant bulbs or wall sconces. The latter may need lonnnng renders to accumulate enough virtual photons...

( Else, Plan_B, hiding new Poser point-source lights within... )

Oddly, none of the Poser gurus seem prepared to discuss this limit. I get feeling 'super-ambient' facility may be a 'legacy' feature, or an accidental oopsie like 'cross-talk' that proved useful. And, in subsequent versions, may be quietly deprecated then lost...

The second route is to pull-on your mail shark-suit, buckle your weight-belt, check your twin SCUBA tanks and pony-bottle, plunge into Cycles...

IMHO, Pp_11's Cycles UI makes using it hard work. Lists should be alphabetic beyond first few 'handy' options. There should be a 'directory', and there really, [b][i]really [/i][/b]should be a [b][i]map[/i][/b].

Okay, rant over.

After brisk discussion at Rendo', and ingestion of [b][i]sufficient [/i][/b]caffeine via several mugs of 'Builders Tea', I've learned the basics of how to get 'Emission' working.

There are two 'gotchas'-- Okay, three.
First, 'Cycles' is [b][i]much [/i][/b]more powerful and complex, this is but the 'kindergarten wall'.
Second, Cycles UI is [b][i]seriously [/i][/b]unfriendly, see rant above.
Third, the FX only shows up when you render in Superfly. So, lots of test-renders.

Okay, you need two test-subjects. I'll use the default prop 'box', usually found in Poser Primitives between 'Bowl' and 'Cane'.
Load one into scene, move it along a few feet. Load or duplicate another. Position handy...

[b]First way[/b]: Super-ambient
Go to Material room, click on first prop box in mini-window or object list.
Select 'advanced' tab. Should now show 'Poser Surface' list.
Set 'Ambient Color' to taste, usually a light hue.
Set 'Ambient Value' in range 1~~10, which should bring up a nice glow.

[b]Second way[/b]: Cycles' Emission (very basic)
Go to Material room, click on second prop box in mini-window or object list.
Select 'advanced' tab.
To right of 'Poser Surface' list, there should be an empty gray area between list and too-skinny scroll-bar.
Right-click there. Menu pops up, 'New Node'.
Follow this right via Root to 'Cycles Surface'. Left-click on this to select.

Right-click in the empty gray area below this small, new list.

Menu pops up, 'New Node'.
Follow this right via Cycles, Shader, Emission. Left-click on this.

Left click and drag the white Emission spot-tab onto the Cycles Surface black spot-tab.
This should create a link or channel.

In Cycles Surface list, left-click the Superfly Root tick-box to enable it.

In Emission list, set Color and Strength to taste.
Test-render in Superfly, iterate until satisfied...

Low values of 'Super-Ambient' and 'Emission' are similar brightness, but 'Emission' does not max-out, may be dialled to 'bleach'.

Have fun !!
