Corona 10/11 - Corona Render Assets loading very slow

[TC]

Just installed v11, the daily build. The scene that I had problems with initially still gets stuck at 98%, loading Corona assets.
As stated before, the workaround for me was downgrade to 9 but also merge the problematic scene into a new max-file. Same scene content, same assets - loading times quite alright this time, given the size of the file. Both 9 and 11 work fine with the merged file.

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!

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.

Hi,

Can you please tell if Corona 11 daily build is slower or just as slow as Corona 10? And Corona 9 still loads faster than both?
Sharing the scene to test it on our end will be better of course.

Will this be incorporated into a new 10 hotfix?

Does it work better for you in V11 dailies?
We won't be releasing any new V10 hotfixes as V11 is planned to be released in about 1 month. :)

We can`t really test dailies due to current office workflow, but this is a major issue.

Hello,

I recently updated to Corona 10 HF2 for a project that required the implementation of some new features.
Today, I needed to perform a simple task: extract measurements from a basic Google Maps model, but it's nearly impossible due to the lags in Corona 10.

I have attached the scene for your reference, and you can experiment with it to measure the time it takes for opening and merging materials.
Currently, I don't have the time to test it with Corona 11 daily build.

Here are my "scores":

[3ds max 2022]-Corona 10 HF2
- Scene loading time:  9 minutes and 50 seconds
- Picking multisub material:  10 minutes


After selecting the materials, I have to wait an additional 10 minutes due to 3ds Max freezing.

I have tested this on:
- 3ds Max 2022 and 2024
- AMD Ryzen 9 5950X
- 64GB of RAM
- SSD

Scene Information:
- 450,000 polygons
- 1 object
- 1 multisub material with 694 3ds Max Physical materials
- 692 small textures

I hope this information helps.

I would suggest the following as the first troubleshooting steps:

1 - Click on the name of your viewport mode (e.g. "standard", in your case: "standard-faster") > viewports configuration > set all the "pixels" resolutions in that window to a low value like 256, then restart 3ds Max and try again
Sometimes the textures are loading extremely slowly when the texture resolutions are set to high values.

2 - Disable your antivirus/firewall (just to check if it has any effect).

3 - Reset your 3ds Max ENU folder (but beware - this removes all your custom settings so it's best to save a backup)

Hello Maru,

Thank you very much for your video and advice. There is definitely something wrong with my machine.
However, before going through these steps, I reverted to Corona 9, and I also have some interesting time scores:

[3ds max 2022]- old settings (display performance - all 4096)
- Scene loading time: 10 minutes (Corona 9 HF3) VS  9 minutes and 50 seconds (Corona 10 HF2)
- Picking multisub material:  1 minute and 5 seconds (Corona 9 HF3) VS 10 minutes (Corona 10 HF2)

[3ds max 2022] - fresh ENU folder (display performance default)
- Scene loading time: 40 seconds (Corona 9 HF3) VS 1 minute and 20 seconds (Corona 10 HF2)
- Picking multisub material: 1 minute and 15 seconds (Corona 9 HF3) VS  1 minute and 45 seconds (Corona 10 HF2)

[3ds max 2024] - fresh ENU folder (display performance default)
- Scene loading time: 45 seconds (Corona 9 HF3) VS 47 seconds (Corona 10 HF2)
- Picking multisub material: 1 minute and 30 seconds (Corona 9 HF3) VS 45 seconds (Corona 10 HF2)

[3ds max 2022] - fresh ENU folder (display performance lowered all to 256)
- Scene loading time: 14 seconds (Corona 10 HF2)
- Picking multisub material: 55 seconds (Corona 10 HF2)

[3ds max 2024] - fresh ENU folder (display performance lowered all to 256)
- Scene loading time: 11 seconds (Corona 10 HF2)
- Picking multisub material: 46 seconds (Corona 10 HF2)



Can you please tell me which resolutions you had in your 3ds Max when you recorded the video?

Can you confirm if you are using 3ds Max 2024.2 and Corona 11 HF 1?

A user who had the same problem fixed it by reinstalling 3ds Max and all its plugins. They made sure to delete any files that were left behind.

According to user, these were the steps that he took:

1. Uninstall 3ds Max and Plugins: Everything related to 3ds Max, and its plugins was completely uninstalled.
2. All folders related to 3ds Max, including any residual files, were deleted.
3. Delete the Corona Folder in Program Files.
4. Re-install 3ds Max and Corona. (Latest version)
