material editor SLOW - i think its a CORONA issue?

[rubensabou]

I have tested this on two 64-core workstations and one 24-core workstation, and the issue is only occurring on the 64-core workstations.

I will oppose all the advice in this thread, because I can already tell you, it will not help. Any big-PC (Threadripper, Xeon, etc..) in high-core version, is pain like this in material editor unless as you correctly shown, you use native Physical Material.
Corona, will have super slow material editor in any remotely sized scene. And it's not snappy even in completely empty scene, unlike native.

This has absolutely nothing to do with proxies. This is technical issue on Corona's side that they just don't care about. I guess majority of users aren't on 64-core machines.

BTW, my settings:
Standard viewport (so no HQ)
Every big mesh is proxy. (most of long opening is due to bugs like "corona assets" etc.. and similar stuff, having proxies makes scenes smaller, but it hardly makes difference in opening after scenes start to feature bloat).
Viewport texture settings 1024px for all 3 types(laughably blurry, so despite having 16GB of Vram, I only use like 2GB per scene because otherwise everything will be even slower).
Basic material editor for editing materials. I only use Slate to create them, but because it's so slow, all the little changes (changing IOR 10perc. here or there, etc..) I do in basic.
All textures mapped locally, on local disc with exact paths.
No plugins whatsoever. No ForestPack, no nothing.
It doesn't matter which Max version. It's the same as long as I can remember. Really makes zero difference.

It's not anything else, it's Corona. Yes you are correct.

This does in no way help with slow material editor, and esp. slow material editor during IR. That's like unusable, I waste like 90perc. of my time and 99perc. of my mental health waiting on shit to unfreeze.
It's what it is :- (.

If it's really all because of QT, then that should have been tried ages ago.

One thing I never tested, if it's connected to materials being applied to scene ( and/or additionally, having "shown in viewport"). So I will test:
- disable show in viewport in big heavy scene
- dis-apply all materials (I don't know, apply them to single box and hide it) just keep big material editor full of materials.

I have this issue on 24-core Xeons and 32-core Threadrippers.

P.S.
Sorry to bother you Tom, still no updates on the roadmap.
I'm really interested to see where Corona develepoment is heading for version 13.

Hahaha well the community is unanimous in wanting that roadmap updated! I hear y'all loud and clear :) Definitely this week, hopefully tomorrow (the 25th). I am just getting confirmation from the devs on what is looking like it ought to be in, and what still has some uncertainty so we won't talk about it yet to avoid disappointment (of course even the things that do get listed are still plans and not promises - all is on track for now with what will be on the roadmap, but the nature of development is that can get unexpectedly derailed at any time).

I am looking forward to letting you all know about our plans!

Any update Tom?
Things are awfully quiet around here lately :)

Yes, roadmap was updated on Sept 27th, there may be more to add depending on how development goes. After updating it, I was traveling last week, so didn't get to return here to say it was updated :)
