@@BrazzyFr you can find me on discord, the username is shopealope

@@JsAnimation24 it’s time consuming to make double sided full geometry foliage, so it’s more of a thing you’d either make or purchase

@@fabiolives did you make the 2 sided geometry? I thought you took a 1 sided plant and modified it in the modeling tools to make it 2 sided… is that incorrect?

@@DannyArtNL I do! I’ll have them in a video soon, I’ve been planning to post it for about a week and keep getting caught up in projects haha

@@BC_Cutler it’s the latter, white is severe overdraw. It will still occur at some angles with any mesh, but is definitely very bad with masked foliage

I didn't test it, I just wanted to compare the difference between masked and full geo for Nanite usage. Many of the projects I work on benefit from the density I can achieve with Nanite, so it is more beneficial for my workflow

Surprisingly it baked just fine! I had to lower the pixel density of the simulation to make it this large so I'm guessing that helped with the total amount of data for it. It ended up looking great after being baked

I was curious about this as well, summarizing what I was able to find: Raster bins in Nanite are used for rendering objects with complex materials, such as two-sided materials, transparency, or alpha masks. Rendering objects in these bins is slower because it requires traditional rasterization instead of Nanite’s optimized rendering pipeline. The goal is to avoid raster bins and let Nanite handle foliage using its efficient geometry-based processing.

@@JsAnimation24hmm but didn’t he basically make it a distinct raster bin? I thought the entire tutorial was doing exactly that?

@@MarioCola I cut the leaves out myself, I make full geometry trees pretty regularly. Got tired of paying for full geometry foliage so I learned how to do it haha

@fabiolives a tutorial would be great!

@@DallasDrap thank you! Some were made by me, some are from the Mawi European Birch Forest pack but with different textures for the bark

@@highfps_pcgaming8836 haha yes, I was supposed to disable skylight ray traced reflections. It messes with AO with ReSTIR

@fabiolives by the way restir gi is pathtracing,to make sure its working disable directional lights,the whol scene must get dark.then add an emissive material ,see if you get area shadows.

@@opsxp23 I have a Ryzen 7950X, RTX 4080, and 64gb of ram at 6000 mhz. Overkill for this project, very helpful for another one I’m on

@@cube2fox now that’s a good comparison, good idea. ReSTIR GI is still a bit broken so if I can get it looking reasonable then I will

@@chelo111 no worries! You would have to purchase full geometry foliage or make it. I cut out the leaves myself for the Dekogon tree. There aren’t many full geometry models on the marketplace, but there are some. Mawi’s three newest packs are full geometry, I sell a full geometry pack on the marketplace, and there are a couple of others out there as well

@@simonevenezuelano11 it’s pretty easy to manage, it just would be good if they published more information on it. For example, if you have a mountain made of hundreds of rocks and make sure the rocks are high enough poly count, you won’t have enough overdraw to matter. Having a poly count that’s too low will cause more overdraw

@@Fafhrd42 indeed, there are some ways around this that I have found though. If less dense geometry is used for the leaves and branches, the performance difference becomes negligible

@@TheHiddenEmpire I’ve also noticed this, it makes sense though. I know Lumen can’t completely ignore the masked section of the mesh so it affects GI when it’s used

@@fabiolives Makes sense, that's pretty much what I figured. It's so much nicer with the modeled leaves, dang! Much more stable and the color is nicer too

@ I definitely recommend it! If you use Nanite you’ll benefit greatly

@@yonghengshouhu haven’t gotten to try it out yet! But I plan to. I’ve been using texture graphs though, very useful feature

@@MrEnderNerd I appreciate it! Let me know if there’s anything specific you’d like to see. I’m pretty much always doing something in unreal

@@daikon711 it’s not working correctly, just an early preview. But I also forgot to disable skylight reflections which is most of the reason it looks that way

@@fabiolives Could you reupload with restir fixed and with side-by-sides vs Lumen in 5.5? Thanks! ☺

@ can do! For the record, ReSTIR doesn’t have a 5.5 version yet so they won’t be entirely equal but I can do that

@@viatorrr the only plugins I’m using here are DLSS and NRD. When you build the NvRTX branch, ReSTIR GI is included but needs NRD enabled to be used

@fabiolives ah thanks, all this time I thought i needed that plugin which doesnt work anymore. did you have the issue where turning on ReSTIR just looks like the skylight got disabled, can't tell if this is just an AMD issue on my end

@ yes, if I remember correctly you need to disable ray traced reflections from the skylight. And this comment reminded me that I forgot to do exactly that in the video haha

​@@fabiolivesi had tried it and sadly it's still the same for me, it's still experimental so I'm just gonna put off if trying to even use it rn. i wish the RTXGI plugin worked tho, would've been nice to have a alternative to lumen

@ yeah, ReSTIR GI still isn’t quite there yet but in the specific scenes it’s good with, it’s nice. I’m enjoying megalights in 5.5 though

@@Viscte it’s the same as building 5.4.4 from source. Have you tried building the normal build of 5.4.4?

@fabiolives I haven't yet tried the non Nvidia build yet if that's what you're asking

@@SUVO_RAW have you tried changing the boiling filter setting? If you’re seeing noise from lighting, that would help it. Also helps to bump up the number of bounces ReSTIR GI does. 32 barely has an impact for me but is noticeably better

@@fabiolives Ok, thanks. I saw the presentation from NVIDIA. They render scenes with only emissive materials and it was clear. I think there is an option to use initial samples, but it is no longer present in the latest version.

@ I think initial samples is still there if I’m remembering correctly. However, it’s very heavy on performance

@ I actually found out what settings to use to get perfect results

​@@SUVO_RAW Could you share those Settings here? Would appreciate it mouch !

@@juancarlosgzrz it’s a setting in post process volumes. You expand the menu under global illumination and you’ll find it there

nope !! they are still working on it

ua-cam.com/video/Y9XPCKQBg8E/v-deo.htmlsi=5K9fvbYVYNbG_fcV

Mostly due to me leaving it at default settings, it definitely isn't meant to be that way and has quite a few options that can be tweaked

@@SanjeevKumar-be4dd I might do that! I’m waiting for the current NvRTX branch to be updated before I do more of these, ReSTIR is a little broken at the moment

@@fabiolives After watching your video i'm really curious about Realtime Path Tracing look with Nvidia Unreal Branch

@@SanjeevKumar-be4dd it’s actually in this video, ReSTIR GI is their real time path tracing solution. But I’ll use it in an area that shows it off more

@@Retro_simone can do! It probably was me, I don’t speak in my videos very often so I didn’t pay enough attention

@@ohel-x7f yes you can, you’ll want to limit the WPO evaluation distance and set the shadow cache invalidation setting to static for that foliage

@@zakaria20062 Lumen can be great for realtime but it depends on the specs of the PC running it. If this is something that a lower end PC will be running, I would recommend using screen space global illumination. If it was for a render I would suggest Lumen or path tracing. I have had success getting Lumen running well for GPUs down to the 1060, but I would avoid it for anything below that

@@Mertiven and it’s even better now! It’s been updated quite a bit. It’s still considered experimental, but it’s so far ahead of this now. I plan to upload an updated video

@@fabiolives what updates?

@@juancarlosgzrz NvRTX was updated to 5.4 and has newer versions of ReSTIR GI and ReSTIR for Lumen now, along with a newer version of the NRD denoiser

Not even close. Static light maps won’t have the same real time beautiful reflections that this does, although that’s not visible in the video. You’re welcome to use static lighting in your own games though.

I only worked with that landscape for a short time so I can’t say with 100% certainty anymore but I don’t think I was using tessellation on it. If I remember correctly I was using RVT with a bump offset to make it look like it

@@fabiolives oh okay thank you for the reply 🫡

@@ChadMaster_ not a problem! You can also achieve a better look than this by referencing height with RVT and using that for different things
