Env. Light Visibility Cache

[Sharlybg]

Yes, like PhotonGI, there is a ".visibilitymapcache.visibility.glossinessusagethreshold" to set the glossy threshold.

So what is the current glossinessusagethreshold number ? And what will happen if we reduce it to make it cover very reflective object ?

I think we already saw what will hapen...

it is 0.05 like with PhotonGI.

[Sharlybg]

it is 0.05 like with PhotonGI.

Is there any way to break this reflection limitation ?

Eh ? It is a feature, not a limitation It handle glossy-nearly-specular surface as specular instead of glossy.

I mean a limitation in a way that if you go too low something like 0.001 the result lead to light weird beahaviour or black spot .... anyway result go too wrong to let it go.

It's a feature that needs to be exposed in Blender

With this visibility cache, before we had artifacts on very glossy objects, now they are excluded from env.cache if they are bellow 0.05 glossiness...

One way or another, they are gonna be noisy. At least from what I've experienced so far.

So my point stay. I mean limitation or no limitation in way that even high reflection object can still be well sampled as it is for less reflective one without artifacts.
It is a limitation to get all the speed unlocked :

If you stay at 0.05 =====>> you get artefact free render =====>> you get too much noise

If you go down 0.05 ====>>you get performance but =====>> Artefacts stop you

you're limited anyway.

It was just my assumption, only Dade knows if it's like that.
