Thank you very much for your coverage of LuxCore. A real and maybe the only real open source and free alternative to commercial giants focused on photorealism. Subscribed.

[@marioCazares]

Thank you for posting about Luxcore, there isn't too much info about it :D

[@djtutorialscgi]

Indeed! That’s why I made these. Thank you!

[@evilotis01]

this was SUCH a good tutorial. i've been trying to create a laser effect in Blender for a couple of days, and saw someone making a passing mention of Luxcore in a thread -- I'd never heard of it, but I downloaded it, installed it, was v confused by it... and this is JUST what I needed. thanks 1000x for such a detailed look at a super powerful, but not super user friendly, engine :)

[@djtutorialscgi]

It is a more advanced engine for sure due to its bi-direction path rendering. Join us on the Discord if you have questions or need help with it especially for the render settings.

One of the best Luxcorerender Tutorial so far. Thank you.

[@heela.3dstudio]

thank you so much, I really needed it and you taught me in the best way.

great tutorial... thnx

Is LuxCore the way to go for me in Blender if i want cool light play within water droplets or on closeups of the eye's lens reflecting onto the iris?

[@djtutorialscgi]

Generally yes it has the most realistic caustics.

[@harishenakala7632]

First of all, Thanks for sharing great info. Can you also make one video describing the addons you installed. seems like it comes handy at times. Thanks in advance.

[@djtutorialscgi]

I might- but I can tell you now! Node Wrangler, loop tools, bool tools, import images as planes, Extra mesh objects, extra curve objects, Manuel Bastioni lab (mblab for 2.8), FLIP Fluids, Screencast Keys, 3-Point light setup, AMD Radeon ProRender, LuxCore Render.

[@harishenakala7632]

@@djtutorialscgi Amazing! Thanks for sharing.

[@spiritwolf5792]

Nice video. Could've mentioned Specular Diffuse Specular (SDS) (caustics seen through glass or mirrors) too.

[@djtutorialscgi]

Thanks!

[@SantoSVD98]

Amazing, One question man... Someone Say that using Lux with CPU Is Better e because of Viewport performance, No Kernel Update and somethings that work Better with Capua than GPUs... Is It true? For example in Cycles GPU Is waaaay Better and faster than CPU in at 360⁰, but in Lux what can u Say to me about Performance, Render Time, Results etc...?

[@djtutorialscgi]

My 3090 crushes my threadripper 3960x on everything in Blender including LuxCore. The kernel update should only be once depending on what you’re doing.

[@SantoSVD98]

@@djtutorialscgi ah, so GPU Is Better in Lux too... Good to know

[@patrickmedina456]

First time using luxcore and I’m loving it! The only problem I have is that my caustics seem rigid, almost low poly compared to the viewport. How do I fix this?

[@djtutorialscgi]

Not sure what you mean by rigid. Sometimes they can be very sharp if the light size is tiny.

[@patrickmedina456]

@@djtutorialscgi ohhh ok I think sharp is a better word for it! Yeah. The caustics were very sharp. Thank you so much!

[@cg.man_aka_kevin]

So, it's actually rendering on the CPU?

[@djtutorialscgi]

Uses both actually. I’ll be doing an updated video on this after my current series is done.

[@cg.man_aka_kevin]

@@djtutorialscgi Ok.

[@basspig]

I'm just discovering Luxcore and I've notice that the render time is always 8 seconds whether on a 32 core workstation with a fast gpu or on an 8 core pc with entry level gpu. I am wondering why this is and whether it is possible to achieve faster renders on the more powerful machine?

[@djtutorialscgi]

Good question- I haven’t seen that happen. Are you on the discord? If you get on there and share your scene, I’m sure someone can help answer your question for you.

[@elenagraur5393]

Hey , it's a great tutorial . Can you make a tutorial with that example with bottle ? (i mean without modeling )

To get this Tutorial working on my PC I had to lower Glossines Threshold from 0.05 to 0.04

How odd? Can you send me your computer specs and OS?

[@hypersonicmonkeybrains3418]

Glass is way too dark without roughness enabled... but that stops the dispersion.... not happy.

[@djtutorialscgi]

With LuxCore?

[@hypersonicmonkeybrains3418]

@@djtutorialscgi The latest version that comes works with Blender 2.92... But no worries if glass it too dark i found you add a touch of opacity to let the light get in. The dispersion though is not looking right it may be hit and miss, for me it just gave an orange hue to the glass after denoise.
