Chaos Corona 13 for 3ds Max - Daily Builds Discussion

Polygonal Region Rendering
Hello, I hope the next version of Corona will have the same polygonal area rendering function as VRAY. This function is so useful. I hope Corona can add this function. Thanks to the Corona team

For any feature requests, remember to vote for them or add them if not already there over on the Ideas Portal at https://chaoscorona.ideas.aha.io/ - we don't track feature requests from the forum itself any more. Thanks!

Hello, the memory is often full these days. I hope this problem can be solved. Thanks again to the Corona team

I have the same issue : Memory leak when using IR > sometimes moving objects or changing materials suddenly memory goes up full of total amount (128GB) normally I use only 44GB for this scene but 3ds max doesn't crash it is just freeze I need to force to close my 3ds max. I also have the same cpu AMD Ryzen 9 7950X.  Anyway I am not alone with this problem.

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?

Could you explain what exactly you are doing and which part of the UI is sluggish? A screen recording would be great.

Update: logged as support ticket #334112

"Camera tone mapping overrides not updating in IR" is now logged as support ticket #334116. I couldn't reproduce it so would like to investigate it.

So, I was plagued by the slow-down problem that so many of us experienced. I upgraded in the hopes that this was resolved. I guess, it was... BUT

Now I'm just getting a similar (and sometimes worse) sluggish experience across my whole PC. Not when rendering in IR but bigtime when opening scenes, when merging other scenes, when loading new materials into the scene. It's so slow that my music stops/lags. Much worse than previous and this only started with the latest daily.

So, 1 step forward, 2 steps back, guys. What did you do to cause this? Something went wrong...

Funnily enough this is pretty much what I experienced when first installing Update 1, it just felt A LOT more resource hungry than any version prior to it.  Having said that, it's not as bad anymore but I can't remember if I changed any settings or if I've just learnt to live with it now

@anyone with this problem, please share any problematic scene with us (even if it's just a teapot) and let us know what your exact CPU model is.

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.

I wish Ondra would chime in at least. Having him again would be so good.

The VFB on the latest daily so so delayed even with tone mapping adjustments.

Have you got a curves operator in your stack?
