Re: Lux measurement using Irradiance feature

Re: Struggling with LuxCoreGUI

As Dade said luxcoreui is mostly a debug tool for developers, not written with end user needs in mind. We know that it would be good to have some kind of "LuxCoreStudio" with friendly UI, and in fact I have a long list with ideas and plans for this, but so far nobody took up the work on it. I would ...

Re: Fire Caustics

Wow, thanks! Mesmerizing.
It even loops nearly perfectly, maybe one frame at the beginning or end is doubled (or it's my player that causes a slight pause).

My bad, sorry, I read "RT Path OCL" in your screenshot for some reason.

Re: Weird mix material behaviour

Does it also happen if you render on CPU?
I remember there was some difference between OpenCL and CPU regarding transparent materials + mix material.

Re: Is this CGI or a photo?

I agree with lacilaci. There are slight imperfections and usually people don't bother making these for 3D product shots.

Re: OpenCL+Metropolis won't render

I see... maybe the new caching could make this renderable though. Maybe, but all the photons that shine through the glass will end up in the caustics cache and will probably still be harder to trace than direct/indirect photons. The problem with archglass is no refraction. For thin window glass (a ...

Re: OpenCL+Metropolis won't render

You'll have to set the glass to "architectural" so direct light can pass through.
Otherwise, all light passing the glass is caustics, and those are obviously very hard to render for unidirectional path.

4. How hard would it be to also add this feature to Blender API?
What exactly needs to be done from the Blender side?
Create a list of points on the surface of a mesh, and write it to a text file? Or something else?
