Title: 3ds max shutdown when parsing the scene
Post by: subpixelsk on 2013-10-31, 10:16:06

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 :)

Try it with the task manager open to see, if it is a RAM problem. If not, then please upload the scene to http://corona-renderer.com/upload/

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

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?

Probably same as http://forum.corona-renderer.com/index.php/topic,1995.0.html
