got it many times..it came for me from some complex blend materials, was impossible even to rest material editor…but drag and drop empty shader ball on blend mat.place solved the problem.
Hey. I got the same problem. C4D with alpha 5.1 and my material editor is incredibly slow. Like 20 sec all the time. But not everytime. Sometimes helped to switch the material editor preview element from basic sphere to the Corona_01(GI). But not always.
Lukas, I think currently this mostly applies to 3ds Max users, but if you have some problem with the C4D version (the public one or a betatesting build?), you should definitely let us know: https://coronarenderer.freshdesk.com/support/tickets/new
I am pretty sure I have this problem, as well as the material windows failing to update after tweaking them in Output or simply loading a new jpg into bitmap. I noticed a large slow down when i was editing the size of Page.sys file on my ssd. After I reset the settings slate Material Editor was back to being just regular slow.
It happens to me also, some times there is a BIG slow down when i pick a material (im using compact material editor) from the scene, and also when i drag and drop to copy a material slot.
Hi. After having installed v1,5 hf2 this has become extreme. It’s impossible to work with the material editor if IR is running. So every material tweaking has to done without IR. Just like working with old mr.
It’s painfully slow, and highly frustrating. No fun at all. Will try to see if reverting to hf1 (or older) solves it.
What about MVC++ and Windows update?
As you can see in my videos, I had this problem too.
But now, everything is ok.
Do you have a problem with 1.3? 1.4? 1.5 (not the daily versions)
Im aback with a video showing the bug, and some insight about it, i been working all day with at least two max instanecs, one master file and the another is used to make some models, materials and so on for the master file.
after a while it becomes this laggy… its not instant, its like the more i have two instances and work on materials on both it becomes slugish..
I have the same problem. I’ve reverted back to corona 1.3 now which works fine for some reason. Non of my colleagues have this problem so it is very strange. What would you guys like to know when I send a ticket to the link you provided?
Hello, i get very ofen this problem, allways by bigger projects. It is really anoyng, this cut the workfow and is increasig
enormly the amount of stress by the work.
and this by almost all changes in the material editor, changig or loading maps, changing colors take sometimes 30 sec.
making new materials and so on. Great that u are looking for solution!!!
So far it seems that this issue (or similar) is specific to Xeon CPUs, but it could as well be “too many threads” or “2 cpus”, so any hints are still welcome.
Other than that, in two (or more?) cases already, the problem was fixed by rebooting the PC. Yes, really.
okey! Yes I have 2 Xeon CPU’s but my work colleagues also has 2 Xeon CPU’s and they don’t have this problem. It is only with corona 1.4 and 1.5 that creates this problem exists. 1.3 and previous versions works like a charm. I will send you guys a ticket and hopefully it can give som more insight to the problem.
