[@chronosschiron]

one other issue i mentioned above is when you get that texture streaming error where its red and need to increase teh pool BE VERY careful as it will give this error too i have 6GB card with 1.9 gb shared and i have no errors now at 2000 poolsize hit tilde r.Streaming.PoolSize 1 ( run your project and see how under it is and go a few hundred more like if its avging 1500 set to 1800 or 2000 ) to do that r.Streaming.PoolSize 2000 be warned this is for my 1660 super and if youhave less vram your going to have to do things like in settings and scale back to low and keep the pool less only other option then becomes MORE vram

Totally agree. This content is absolute gold. Someone that knows exactly what they're talking about, and doing it clearly, concisely, and lettings us know pros/cons of each option. No fluff. All gold. I just tried to like the video, seems I already liked it in the past :D

[@Milesinck]

I can't thank you enough. I have searched non-stop for 2 days, unable to discover why my render kept failing at the first or third frame. After enabling virtual texturing and then selecting the 'enable texture streaming' option, my render has finally started and I'm able to render on HD with only 4gb vram. You've singlehandedly saved my project (For anyone having similar problems; I have a GTX1650 maxQ, 8gb RAM of which 4 is vram)

So far, these videos have been AWESOME! I like this one and full disclosure, I do have a 3090. I thought sure why not try a huge open landscape with world partition. Then I tried adding the water feature and my VRAM shot to the 24GB area and pretty much stays there. Luckily just trying things out but can't wait for that feature to be optimized because when it works it looks great! I am still learning and these videos are very nice to have.

[@Vanderer11]

Great vid! :) Learning optimization techniques can save a lot of time and nerves for almost any UE user. I'm using an old gear, GTX960 4GB, Phenom II x955 and 8GB ram and I can't recall when my last crash was (expect when I tried to import metahuman ^^). Trick is to optimize all of your assets, even those from marketplace or megascans (channel packing, for example, is not set up by default), since they are often designed to look as good as possible for marketing reasons, so their materials are just too expensive for many uses. 4k textures - only when they are really needed, so in my case - almost never. For highest quality cinematics only: sure, a lot of Vram is definitely required, but as for now, you definitely can make beautiful games with an old rig like mine without big troubles, so to anyone demotivated - don't give up! :)

[@WilliamFaucher]

Totally agreed! That said, optimization is a time consuming process, and time is a luxury in production. In Film, we rarely have time to optimize things perfectly. Game development can go on for years at a time. A film production does not often last nearly that long. At least not the VFX/CGI side of things!

[@DannyNetwirk]

I imported a 8k landscape and tried to render out a quick sample of the scene. Each time i hit the render button, it gave me that same error. Started troubleshooting and figured out that the landscape was the main issue. I ended up trying your last tip. Enabling Virtual Texture. That trick worked for me. Thanks again!

[@tazwinsdevchannel]

Has enabling Virtual Textures had any downsides for you? For me all of the textures became grainy/noisy whenever I moved my camera, although it could just be because of my low resolution when trying it.

[@DannyNetwirk]

@tazwinsdevchannel yes, that happens with me too. If you want a specific texture to be high resolution, you can manually do it by right clicking on the material and turning off the VT.

[@tazwinsdevchannel]

@@DannyNetwirk I might look into it then. Just re-read what you wrote originally and my issue is probably same as what you had. I imported a 4k height-map and made an 8km x 8km landscape. And the VRAM usage per landscape streaming proxy is crazy. Which is probably why I can't render. Did you find a way to lower that as well?

[@m1sterv1sual]

Cooltips! Most artist that come from traditional CGI background still don't have mentality of optimization. As you said, planning and knowing what needs detalis and attention is crucial for optimization and headache free editing. Nice video!

[@WilliamFaucher]

True, fortunately most of the optimisations you do in Unreal are more or less the same as what you’d do in VFX. Turn down the polycounts a bit, go less nuts on foliage, that sort of thing

I just found out today about the gpu visualizer for a specific frame, hotkey is ctrl+shift+, you can dig down into whats causing a still image to be having lag, I was at around 80ms with 4k textures and raytracing enabled and turning volumetric fog for the exponential height fog off helped a fair share. Disable RTX when unsure alltogether.

[@oliverkoch3235]

Lifesaver!! Thank you William

[@samuelenslin1850]

There are a few other obscure tips floating around, what did it for me was simply going into the nvidia control panel and limitting Unreal to 30fps. No crashes since. Mind you, crashes have been waaay less frequent with unreal 4.26 and even Unreal 5.0EA. The switch to shadermodel 6 as a requirement seems to have caused a bunch of issues.

[@ghostdesign-ue4604]

Many thanks for the hints. First i thought it´s a DX12 and raytracing issue. To be honest, i haven´t had the VRAM in mind since i switched form 8 to 24 GB and i haven´t had such an issue with 8 GB before. The hint with Virtual Texturing saved my life :). Before i had up to 22 GB Vram usage now i have 12-14 GB, everything runs fine again. Thanks a lot

[@WilliamFaucher]

Cheers man! Glad it helped! Be sure to check out the TDR tip in the pinned comment here, this is also a huge lifesaver.

@@WilliamFaucher I will try it out. It seems not just the d3d device can be fixed by using the virtual textures. I have a larger medieval scene where i had no problems so far. Then i upgraded my PC and it crashed while loading the map. No chance to open it, no attempt to fix it, helped. Manged to enable virtual textures and violá it works

[@mikeseto6827]

All great points and I have being doing of some these already like keeping my eye on the GPU usage and reducing screen percentage. Also a big help has been putting high memory usage assets like characters/crowds into a visibility layer that I toggle on\off in the sequencer as well as for during editing. This reduced the frequency of UE4 crashing a lot. Even with using a 3090 my UE4 still crashes. Wonder if I can use my old 2080 RTX along side the 3090 RTX in sort of SLI mode, last I heard it was not supported? I will try DLSS and virtual texturing moving forward. Great channel and topics covered!

[@WilliamFaucher]

So from what I've heard, DLSS doesn't work with the Movie Render Queue, unfortunately. Have you considered trying to change your TDR value? By default TDR is set to a short value of about 2 seconds, if a GPU process takes longer than that, it can reset the graphics driver and cause a crash. you can read about it here. It's a document for substance painter, but the same applies to Unreal: docs.substance3d.com/spdoc/gpu-drivers-crash-with-long-computations-128745489.html

On the rendering lower resolution issue: I'm going to invest in DaVinci Resolve Studio largely for the awesome upscaling in Studio 17. I haven't tried it yet, but it looks amazing.

[@WilliamFaucher]

Yeah pushing screen percentage to 200 often causes a crash. If I recall correctly, SLI isn't supported in UE4, so no, that won't solve your issue.

hey Will just want to add its a good practice to always delete stuff that isn't needed for the render or if it is a very long render use blueprints / keys to hide those stuffs we will no longer include in the shot for example a forest landscape cinematic with about 14 trees in the shot only, it is safe to delete all the other ones (working on a clone map of course) cheers

[@peterbikki2758]

One more huge VRAM spacer i believe is to use "High Resolution" tiled images (lots of tiles!), it basically crops your image into smaller ones, meaning that you never have to use huge framebuffers. I could render out 8K images with this on shots that were GPU-crashed on 2,5K.

[@WilliamFaucher]

It can certainly work in a bind! Although I am generally a bit reluctant to use it due to the artifacts it can create with screenspace effects and motion blur due to the tiling. But yeah if you're screwed in production it's awesome to be able to at least get the frames out!

So far I've been using an RTX 2060 Super, Ryzen 7 3700x, 64gb ram. I generally don't recommend laptops because the GPU's in them are not as powerful as their desktop versions.

I looked into the TDR Delay, but that doesn't exist in my registry? Unreal Engine is updated to 4.21.2 currently and Windows is updated. The first crash happened after a 3.5 hour stream of Satisfactory (which runs on UE4) and now, it won't stay opened for more than 5mins. Any thoughts?

I really can't speak for games, that isn't my area of expertise. The error message usually shows up when you run out of VRAM though.

[@jymnasium]

@@WilliamFaucher Thanks for your time. I figured out my problem: My C drive was too full, and Windows does really poorly when that thing turns red ;)

i have problem with ram. i have 32G Ram, after lightmass building reach 100% and started the encoding process , ram started to filled up until UE crashed and closed ... do you know whats the problem?

[@wilismatrix9847]

Thanks for the tips ! is there any source where to find all those commands. I find only fragments in the unreal engine documentation ?

[@WilliamFaucher]

Good question! I haven't found a single large database, I tend to find them scattered around the internet. There are SO MANY console commands it's pretty nuts.

Thank you a lot 👍 You are cool 😎

[@WilliamFaucher]

You’re very welcome! And thanks :)

Sorry for spamming... another easy way to decrease vram usage is to switch your viewport to "wireframe", fly away from the main part of your scene (to the skybox) and make the viewport window really tiny. It saves about 50% of vram usage and just then start your render queue.

my issue was ray tracing being enabled combined with 4k textures for hundreds of pieces of foliage, and swimming shark models with equally 4k textures. turned off ray tracing, solved it. went from 3-5 hours and crash, to 2 min 20 sec for a 4k render. my other scene while only took 25 minutes to render under 4k but had a lot less texture wise to deal with so my issue was memory load even with shared memory.

This and streaming textures were giving me issues thx!

on my last vid i got the error on a few shots, i found that raytracing global ilumination if set too high caused it. reducing the bounces and spp solved it for me....iam struggling to find/settle on which combo of lighting setups and renders to use whilst excluding path tracing due to render time.. i want to make fun videos and like making them in one or two sessions so rendering has to be fast enough to be productive.:}.camera and post process i tweak far to much, trying to add a look but iam finding its really destroying the quality in many shots. thanks

If anyone is getting loads of crashes with Nvidia, make sure you have the right STUDIO drivers installed, I was running the regular 'Game Ready' drivers, but getting the studio drivers installed has stopped crashing for me! Doing registry edits only made the problem worse for me

Thanx PRO
