Thanks. We are running up to date windows 11 24h2 from memory. Have just upgraded to corona 12.2 so we will see how that goes. It’s odd how it comes about as it’s not all the time. I do notice the disk is in use like it’s paging but we have 256gb ram and the scene is ‘only’ taking about 100gb. We’ve also deactivated some of the auto ram optimisation check boxes which were on by default I think.

Hi, did this get solved? we have been having this extreme slow down as well on complex scenes. Plenty of spare ram (256gb installed) but the cpu drops right down to about 15% and gi and parsing also take a long time. It’s not that the scenes efficiency drops with AO or rounded edge (although it will be a slower scene to render) but that windows is limiting access to the cpu.

Using windows 11 up to date and corona 12.1

Thanks

Thanks Tom. That's a shame. Is there any possibility this feature will come to pattern? Essentially allowing an interlocking non square source shape. It would need to offset alternate rows by 50%. I cant seem to get the randomiser to do this even with stepping, unless Im missing something?

Is there any further info on the new fit in custom object space feature? I am hoping it now allows us to do an offset pattern like a stretcher bond plank floor that interlocks rather than always having to be a square shape and cutting geometry which messes up texture randomisers. I cant seem to get it to do much though on first go.

Is it right that the tiler dosnt work with bump? Doesnt work for me but the same node does work with displacement. Seem like a strange omission, so not sure whats wrong? Just a a basic white tile with a black grout. Tried adding a blur to help but its flat as a pancake. Displacment works fine.

Hi,

This is known and has been discussed here:
https://forum.corona-renderer.com/index.php?topic=41757.msg220610#msg220610

For now, you can use CoronaBumpConverter to make it work.
Hope this helps.

Thanks, sorry I missed that.

Love this feature, hope it continues to mature.

As said by others a random mirror option would be really handy and hopefully one of the easier requests.

Ultimately a full tile pattern design editor would be fantastic and such a time saver. I really like how responsive it already is switching between the pre set patterns.

This would be my number one feature request for R12 personally.

I'll try and archive the scene as its big so wil need to be overnight probably.

Here's a funny one. If I open the scene through Max with Arnold set as default like it is when Max opens, then corona crashes the file on opening after about 30 seconds. If I manually change the render engine in the blank opening scene to corona then try and open the file, the scene loads. Looks like corona or max isnt switching to the chosen render engine (corona) quickly enough in the load cycle? Its problematic when trying to render the scene with pulze render manager as I cant manually do that switch so it crashes shortly after starting. I could see if setting up the opening Max template, switched to corona helps, if the none GUI option even reads that?

OK Loading an other scene and unfortunately, still getting the long wait on the loading corona assets phase with the CPU running one thread and very little RAM / Disk / Network activity. The scene will eventually load but not sure what corona is thinking about during this phase. Not a particuarly heavy forestpack scene.

Not done a closely compared time test but the latest one I'm sure is faster. Also the disk or RAM or CPU is always moving, unlike before where it was just hanging without activity for ages. Will keep an eye on load times next times with these large scenes. Good job!

I'm getting this with Max 2024 and corona 10.1 / 11DB.

Large scene that was rendering OK. Its the same on two PCs and have loaded the scenes many times to try. The corona process stops after parsing. Interactive works fine if done before trying to render full res. If I try the interactive after a failed full res render it usually crashes.

I note that chrome remote desktop could be a cause, I have been using that recently but I'm really hoping thats not it as its a really useful tool. I was also told the otherday that dropbox isnt recommended by autodesk. Seems like the useful tools are being rulled out and we should never leave our desks ;-)

EDIT: Hmm actually I have tracked it down to a random railclone object. If I switch it off it renders fine. Odd that interactive works and the main render just concs out.

+1 for this, glad I'm not the only one. Working on a few large files and they can take an hour to open. The current one is a particularly big 6GB file. Interesting that the Max log says the scene is loaded within 3 mins. Task manager is running at single thread speed and the RAM usage is idling around 20GB, so its slowly working on something but not building any RAM, there is zero disk activity, its been in this state for about 35mins and counting now. Eventually it usually opens after approx an hour. In other scenes I have put it down to lots of forestpack but only a few bits in this scene. I can try and archive it but I am guessing its going to be huge with all textures and assets.

I think we notice this loading corona assets more in Max 2024 with the loading bar feature which is useful.

EDIT: OK after 35-40 mins of idling around at 20GB ram and no disk activity, it bursts to life with loads of disk and cpu, ram quickly builds to 55GB and the viewport gets generated. Not sure what its chewing on. My guess would be material generating related. We were trouble shooting some crashes in another large scene and uninstalled corona to test and the scene geometry generated very quickly, just with all black materials.

Hmm getting more crash on loads with some larger scenes in the loading corona assets phase with the latest beta. Quite possibly forestpack related again. Have rolled back to 10.1 for one scene (no humano people in that one) and that loads again. We have one PC that seems to be more sensitive to crashes, same spec and software versions and plugin versions but one PC loads some scenes the other cant and both crash on one particular scene. Very odd.

Thanks so much for fixing the forest pack crash on opening bug with that latest beta. Saved a massive headache we were having with humano people killing scenes.

Can you expand on this? I too use humano, but they are so so so heavy that I've moved to anima.

Are you saying that forest pack somehow helps with this? Or are you just referring to a specific bug?

It was a bug it seems with how forestpack and corona interact when loading through some object materials causing a crash on load. For us it was with humano figures.
