Sub-Pixel and Clamp

[Morne]

Hi all

So with the advancements in the latest 3.30.04, I found something from a few years back and just want to see if this still work like that:

"(vlado 2009): "If "sub-pixel mapping" is on, first the sub-pixel values will be clamped, and then they will be averaged together. So your final result will be (0.5+1.0)/2=0.75 (light grey).""

Yes, this part is the same...

Best regards,

If I have sub-pixel on and clamp at 2.0 does that also mess up my comp for building up of the beauty via the elements? (It looks like it does, just want to confirm)

The comp mostly works. The specular however is about 0.5% brighter compared to the beauty
However, the biggest issue is the refraction. It is doubling up for some reason. The comp is correct WITHOUT the refraction channel, but then the selfilluminated objects behind glass don't show up.
Very weird

That's odd; which channel are the refractions in then?

Something weird here. It's almost as if thinner objects like windows and wine glasses have their refraction in the GI, but thicker objects like booze bottles with liquid in has it in the refraction channel.

Sounds strange and you may think I have the GI windows confused with the refraction. But I'm not. If you compare the windows and glasses in the beauty pass to that of the built up comp without refraction pass, then it looks the same. As soon as I add the refraction layer, the windows and glasses double up it's brightness (and yes I'm working in 32 bit)

looks like refractions in your glass mata are affecting all channels
