3ds max shutdown when parsing the scene

Hello everybody!

I came across an annoying problem this morning. I use Corona for one of my current projects and I´ve successfully rendered a few pictures with no problems at all. Today however when I tried to render a scene, 3ds max crashed while parsing a scene. Screen just got to 2 secs and then crashed and I really can not figure why this happens - firstly I thought it could be caused by high fresnel IOR (999) on some materials, so I lowered this value but it didn´t help at all. I use PT+HD with 128 PTS and MSI 400. I also use noise displacement on carpet with projected size of 0.5 and max.subdivision per poly of 1500. Any help would be kindly appreciated :smiley:

Try it with the task manager open to see, if it is a RAM problem. If not, then please upload the scene to Renderer for architectural visualization - Corona | Chaos

Hi Keymaster&thanks for the reply

I guess it might be a material issue as when I turned on override MTL with default Corona MTL, the scene renders properly without crashes. However override exclude/include feature doesn´t work for me for all of my models so it´s kinda difficult to say which material is causing the crashes..It´s definitely not a RAM problem (I´ve got 8gb installed) and when i encountered a crash task manager showed only 3gb usage out of 8.. Please if you could take a look at that scene I would be grateful

ok, I will.

Thanks, I realized that crashes might be caused by displacement that I use on carpet and wall frames (when I switched off displacement, scene renders properly)..though I don´t know how to fix this..

EDIT: I came across a possible explanation - I used a jpeg displacement map, lowered max.poly subdivision and tesselated my carpet mesh and it seems to be rendering ok now. Maybe noise as displacement is not working in Corona?
