Re: What If Luxcore RT

Of course it is a process they are not going to jump to full path tracing in month but it the end goal leave rasterising to realtime ray tracing.So far I'm seeing lot of hybrid solutions rather than leaving rasterization. Raytracing gives fast and high quality shadows, proper reflections and refractions, but for GI it is horribly slow.
thanks for the update but lumen is going to even redifine all that.This is quite an outdated information right there
lightmaps can be auto generated on import
the custom lightmass settings were popular for cpu lightmass which is completely different tool in both quality and speed compared to the new gpu lightmass which is better and much faster and currently in 4.26 beta also has denoiser options.
Theses tree are gorgeous. All that plus volumetric in realtime will be hard to beat for sure.Reason why i still say that offline renderer must drastically improve Performance. thanks Laci for sharing.here's an 10 second baking VLM grid example on trees, something incredibly difficult and slow in old cpu lightmass:

Great quality renders. What about the lighting workflow is it possible to use just an HDRi for interior like we do with Offline ? or we still need tricks ?Also I disagree about quality:

I easily take this quality in realtime over waiting for a single render even minutes. And many clients will too.
We are at a very Big revolution Era in Computer graphic things are moving fast in all direction hardware software. Lot of things become rapidly obsolete It is interessing how it is gonna unfold and give us a big picture of what is the way to go. i have my eyes on every possibility and the old unreal didn't take more than a couple of days to start using it so i guess the new one are going to be a lot easier and less time consuming.This is what rtxgi or ddgi does, and not only it runs on directX and RT cores but it is also highly dependant on probe density and from the results I've seen it falls apart rapidly if smaller objects are indirectly lit in a larger room for example. At some point it might evolve into something more powerful but right now it's a bit complicated and also not sure how pathtracer would use probes and how it would impact quality.
