plugin management update in 3ds Max 2023?

[xiesansi]

Hi,

I'm developing a plugin, which has 2 states on and off. Some data will be kept in the memory when the plugin is on.

One user reported that when using the plugin with 3ds Max 2023, the state would be changed from on to off when he had a break.

and I reproduce this only for 3ds Max 2023, with a 15 mins break.

I wonder if the user switch to another window or do not operate at all, the plugin would be uninstalled or cleared or something?

is there any way to keep it on ?

thank you in advance

a) Python, MXS, C++ ?

b) which type of plugin? GUP, Modifier, Helper, ..?

c) can't you save this "state" to disk/registry for instance?

Hi,

thank you for the reply.

1) C++

2) GUP

3) besides the states, some cache will be stored in the memory, and the cache will also be cleared, and it's not easy to save because its size depends on the max file size, which could be several gigabytes

hmm.. have no max2023 here.. if you returned GUPRESULT_KEEP in your code, it might be a new Max2023 issue?

have you tested in an older release?
