@Bjoershol @michaltimko - was it caused by too high resolution? Is it working now?

Yes, it works now if i keep resolution down.

Even my smallest preview renders I send to my clients are 2560px, but usually I don't go lower than 3000px even for that.
2048px is just brutal limitation for 2025 I am afraid.

Same. Was thinking that i can skip stable diffusion but 2k is quite limiting for many. My finals are between 5 and 10k, mostly in bottom range.

The AI enhancing icon is greyed out in the VFB, even after adding the render element. Anything else we need to do in order to use it?

Same issue, tried different scenes. It`s not greyed only if i use IR.

Corona version: 12 Update 1 (Release Candidate 1)

Not sure if this was reported already but there is small but quite annoying bug when IR is set to stop after certain number of passes and you are tweaking parameters in classic/slate material editor or anywhere in 3ds max. Once the target is reached (for example 6 passes out of 6) - max will deselect your cursor from where you are currently at with your mouse.

For example tweaking bump value require you to click into bump "field" every time IR finishes all the passes instead of keeping bump value selected. Or if you are tweaking UVW map - after typing desired value, IR finishes and deselect you out so instead of typing value again and pressing enter, you have to click into the field again.

Another issues i have is corona error messages popping up from minimized state randomly (quite often).

I couldn't reproduce this in the final Corona 12 Update 1. If it's still happening to you, could you provide a screen recording?

I can reproduce it even with simple teapot. I`ll prepare scene with instructions and upload.

Regarding performance - im also experiencing what was already described many times (threadripper 64c, 256gb). Im using corona since pre-alpha when Ondra was coding it alone and we were testing new stuff at 2am morning talking on Skype. I had more APM in Corona than in Starcraft Diamond league while working, it was so snappy (its just very strong nostalgia).

Now its more about waiting until max unfreezes so i can finally replace texture or pan 5k image in buffer from one side to another while zoomed in. Im very happy how far Corona is right now and i also understand that i can`t compare much simpler builds with current situation so i hope this performance issue will be solved in upcoming months because sometime its very frustrating.

Same issue , it happens all the time for me in various scenes when rendering high resolution images (5-10k) , stopping normal rendering and starting IR. Whole max will freeze, eat all the ram and hangs whole PC.

Just curious - anything changed between RC1 VFB and previous daily ? On 3990WX, VFB was always laggy/unresponsive, especially when zooming in, moving around the image at higher resolutions etc.

VFB 2.0 (previous daily) solved that for me, it was super snappy and responsive. Installed RC1 yesterday and VFB feels thesame like always did. Zooming in or out takes sometime 2-4s. Panning inside the image at 100% zoom is laggy and whole max freezes.

« on: 2024-03-07, 12:55:44 »

I always set IR it to force PT and set some pass limit like 5-7 (depends on the scne). That way you are lag free when it comes to mat editor or max ui. Another option is to use IR in the viewport. Not sure if its just for me but its way more snappy than having it in separate VFB window.

glad im not the only one - ive even spent thousands on updated hardware thinking it would fix the problem.  Its literally been like this since i started using max over 10 years ago.  In fact, i think its gotten a little worse.
@CoronaDevs - i think this needs to be looked at for sure.

For me, this biggest time waster over the years is the UI (material editor) - i know its not a corona thing (or it could have an impact?) - however the material editor, becomes slow and sluggish, mainly in heavier scenes (not really that heavy, fairly detailed interior scenes.  2-3 seconds for things to open.... and i do have the most of the latest hardware/software.... again, not sure if this is solely a autodesk thing or a combination between autodesk and corona materials, however its just so sloowwww and it kills my patience... it sometimes feels like im using a intel pentium from the early 2000's..... its 2024, UI, all of them, should be zipppy and we shouldnt be held back by such nuances.

I get that too: the material editor becomes really so slow sometimes, especially when IPR is running, up to the point that I have to stop the IPR, only then I'm able to tweak my materials in the SME, and only then I start the IPR again to see the results. This isn't how things should be: ideally I wouldn't have to stop the IPR in order to be able to tweak the materials, but if I don't the SME UI is just sooooo slow, it's unbearable.

When volume effect is enabled inside of CoronaSky, clouds are being cut with straight line. Is that considered as bug ? I dont think its a feature, looks very unnatural.

Volume effect and clouds are currently not supported together.

We have it logged, but don't have any ETA on when it might be fixed.

Thanks,

Thanks for letting me know. I do lot of exteriors lately with land mass visible at the distance so i use this feature A LOT. Hopefully it`ll be fixed soon. I`ll keep photoshopping for now.

« on: 2023-05-18, 18:13:03 »

I was about to write some feedback after trying new lister but I will just second this post instead.
I agree with every single point. Lister is heading in good direction, but in case of proxies, I cannot see using it instead of Corona Proxy Lister plugin, all the funcionalities mentioned above are a must for new lister to become user friendly.

Also changing previz type on old lister was quite easy, with one click from none to point cloud etc. Now i have to manually use dropdown menu on 50 scatters separately. Not sure if that was an issue in old scatter list but if there is something already selected in the scene, clicking on "sel" button wont deselect that object automatically to open scatter settings. I have to deselect first and then click on "sel" again.

I like new proxy lister, its snappy and fast but for managing huge amount of proxies, id love to see some features from 3rd party script (CoronaProxyLister) but not sure if its possible to implement them this way.

- manually selecting proxy file in the scene which is instanced and part of the "instance group" is not highlighted in new proxy lister. So basically selecting any proxy which is instanced = you cant find highlighted in proxy lister.

- would be possible to add toggle to disable grouping of instanced proxies ? I basically have no idea where to look for specific files becase all i see are just groups (filename visible but important is how is file named in the scene) > https://i.gyazo.com/2f4f6ab53a507845ea4ddd04fc008b64.png

- I would love to see ability to use shift and ctrl while making selection instead of clicking on "sel" button. Selecting 150 unique proxies which are randomly spread in the scene by clicking "sel"  button is very time consuming. It would take 5s to just hold shift and select first and last > https://i.gyazo.com/be428b8fd09cc571ac70a74a74b1bdb8.mp4

- I also miss ability to change properties of group of proxies which are not instanced. For example, i have 200 unique proxy files in scene but i want to quickly select them, change previz type from wire box to point cloud. In CoronaProxyLister i can do it quickly by selecting said proxies in the scene and with click of one button change previz type for all of them > https://i.gyazo.com/64e202ea545d9b104e7ff1dbeb559c14.mp4

Volume effect affecting corona sky or HDRi (if CoronaSky is present in CoronaSelect slot with HDRi)

HDRi https://i.gyazo.com/32f4530a28563472dd4675e1885bb1c8.mp4

Hi,

This is reported on the forums already https://forum.corona-renderer.com/index.php?topic=37552.0

We have it logged.

Thanks,

Rowan

Thanks for info. I dont mind having option to use volume effect with hdri, whats causing issues is that sky is being cut above the horizon. HDRi too.

Anyone experiencing crash during IR while moving objects in the scene ? Its probably related to ChaosScatter when exclude spline is used. Im trying to replicate it in empty scene now. Every project is randomly crashing if i change scatter settings or move objects. Everything will disappear from IR except sky and max will crash.

Another weird thing - clouds being "cut" in distance so they dont continue behind the horizon. I found its caused by volume effect. When turned off, its okay. It affects also hdr if there is sky in CoronaSelect slot.
