Lets make Lightmass EPIC (and understandable)

Do people leave on texture streaming for arch viz ? I turned it off completely as it was becoming very annoying, i figured it's only needed for people making large games ?

Sure thing, glad we could make some improvements, and the form in which you presented the problems made it very easy for me to investigate (simple scene with download, clear demonstration of serious problems). Thanks to everyone who helped in this thread.

This is just a step in the right direction. Once you guys get 4.11 we'd like to know what the new primary limiting factors are for Archviz. We won't necessarily be able to solve them all due to time constraints, but at least we'll know what's most important.

Daniel, what would be nice is if you guys could unlock the max resolution (2048x2048 iirc) of the rendertargetcube texture. Some of us are using that to fake better reflections for our windows and even if the performance drop is huge it's not big deal because we'll use it to make stills or 360 pano!!! I know some forum members have done it themselves with the engine source code but it would be nice to have it already unlocked!!! Thanks and good job on lightmass!

Yep... it's better to leave them on, with additional command r.streaming.poolsize 4096 to give you more room than the default 1000.

Unless you know exactly how many and how big the total texture size will be for your project. Don't forget to put light maps and shadow maps into calculation as well.

If you turn it off completely I find that the initial loading time can be very long tho. With a good streaming pool it works well imo.

[Mentholblue]

I see, my projects are such that if i run out of gpu memory it means i need a new graphics card not a poolsize rethink :-)
In all seriousness i was getting odd effects. I would increase pool size to 4000 after looking at relevant threads on this site, stats were showing a lot less than the limits but i was still getting problems so i turned it off. I launched the culprit project with texture streaming turned off and didn't notice any long loading times (3 rooms few items of furniture) only have a gtx 960 4gb. Maybe it's good to keep in mind what you pointed out as my scenes increase in size heartlessphil.
Cheers

Usually your method is ideal but I had a scene where it would take more than 1 minute to load because of -notexturestreaming. It's a bit long! Maybe my project wasn't optimized enough. Very possible.

It's just the texture streaming lacking memory.
use the command r.streaming.poolsize 4000 (it's 4000mb versus the default 1000)

By the way your scene looks good (lighting)

How do you access the window to paste the command? Thanks!

In Editor press tilde(~) and type "r.streaming.poolsize 4096"
For packaged game, in Level blueprint add node Execute console command after Event begin play and type the above command in it

[RI3DVIZ]

Thanks, is that command needed for each project or does it effect the engine for all projects?

[tupikp]

It's basically a "console command", so it only affecting project that use this command, not the whole engine. Put it in a blueprint is a good practice especially if you are going to give the final result to your clients.

4.11 lightmass portal , just preview mode
is better than 4.9

[heartlessphil]

Can't wait to test it out... Gotta reformat and install win10 before, it HAS to be done at some point anyway! Looks very clean!

[RI3DVIZ]

tc22, looks great! What is your lighting set up, just hdri?

[Mentholblue]

Nice, tc22. Non blurry mirror like reflections too, not seen that before (maybe that's just me)
Can you give your hardware spec, settings and render time ?

hi there,

regarding the newset preview 4.11 build, i have a question.
how to enable embree? i downloaded the newest library from intel, and i tested it with embree on and off in the ini file and actually, i had a slightly faster build time without embree (2% faster) so my guess is its not using it even if its enabled in the ini file and the build times are pretty much the same. and yes, i have a intel processor.

any words of advice?
