Where's Fresnel on Glossy and/or node for mixing?
Re: BlendLuxCore Development

Glossy has these options: https://wiki.luxcorerender.org/LuxCore_ ... e:_glossy2
What do you mean exactly? A view-dependent mix factor like the Cycles "Blend" node?
Currently LuxCore does not offer this, but I think it could be implemented.

__ what are the relevant scenario for that ?
__ why we didn't support this since lux 0.8 as we accuracy oriented

The Fresnel "mix" is already embedded in materials like GlossyCoatting, GlossyTranslucent, etc.Sharlybg wrote: Tue Feb 13, 2018 11:38 am __ why we didn't support this since lux 0.8 as we accuracy oriented
Adding Fresnel driven mix is easy, the problem is that all recursive materials and textures (i.e materials referencing others materials) are kryptonite for GPUs.

I did not get around to implement IOR support for the glossy node yet.
However, as far as I know the IOR is just an alternative way of specifying the specular color (or rather, brightness).
In both cases, when you use specular color or IOR to specify the reflection brightness, the material will simulate the fresnel effect.

Yes, have noticed that fresnel with glossy is present, but only intensity can be controlled now.B.Y.O.B. wrote: Tue Feb 13, 2018 12:31 pm I did not get around to implement IOR support for the glossy node yet.

Nice to know it's coming in.
Thank you.

Thanks to Philstix we now have a node with IOR presets - and you can even search them comfortably.

Hi guy !
just wonder if it's possible to implement a feature that allow us to save render without stop it.
___ User select file type(jpg/exr/png) and target folder
___ then another setting to define saving frequency ( by sample/ by time)
Or at the end of the render
