Title: R25 scene crash
Post by: Stefan-L on 2022-02-14, 20:14:52

Hi

i have a bigger scene which crashes on one machine in r25, but not in r23 with same corona ( both latest beta 8 from feb 2 2022)
a slightly older version renders fine(before i added some assets)
it also renders ok on corona 6 and r23 on same machine

it also doesn't crash on my other machine with same corona 8 beta  r25,

all pcs have the same OS, same ram and same extentions (corona and same vray verison installed)
no bitmaps are missing


i tried with de-installing vray on that machine(in case there was some leftover ion the assets)
when i open the scene then it doesnt find a vray shader (so there seems some hidden mat or shader, but this should not crash and doesnt crash on the other machine)

i disables "render 3rd party materials" in render settings
ram is plenty (59% usage only in total)

can i send you the bug report to check that that is, i am out of ideas?

Hi Stefan,

Sorry to hear you're getting some crashes. In case there might be some ''left-over'' materials in the Node Editor, can you try deleting all the views? For example: Node material editor -> View -> Delete View for each view including Default). This will remove any such "forgotten" shaders. Another thing to try is to copy/paste the entire scene to a new one to see the outcome. If the above doesn't help, can you then please send us your crash reports and possibly the scene?

Thanks in advance.

after some more hours debugging i find some left over vraybitmaps from some assets i downloaded make r25 with beta 8 crash on that machine(not on my main)

i do NOT use the node editor, that are some assets from CGmood i think.
the corona converter seems to keep the vraybitmap and not to convert it to corona bitmap or c4d bitmap.

as it is very hard to check 500+ materials for such things  it would be really great of corona could ignore such 3rd party shaders, and not crash ( i deactivated render " 3rd party materials)
maybe some similar for shaders?

or is there a way to remove such non corona shaders automatic?
(i did already try open in a c4d without vray installed and resave, that wont eliminate them sadly)

thanks
Stefan

The "Corona Private Uploader" in Beanz's signature, if you mean sending the scene file, crash bug reports, etc. (or the links in my signature :) ). Be sure to tell us the file name here too, though. TY!

i sadly have yet to clear some things if i am allowed to send the affected scenes, in meanwhile it is in more than one scene.

no other has crashes in v8 betas and r25.017?
i cant find a pattern, but it always render ok if i end up rendering it in r23 (with same v8 beta) where it works ok, must be a r25 related issue
