siddharthkolte Posted January 28, 2015 Share Posted January 28, 2015 Looks like a Normal problem... you can check the normals of the objects that are missing they might be inverted. If not then just try resetting Xform... Link to comment Share on other sites More sharing options...
erkutacar Posted January 28, 2015 Author Share Posted January 28, 2015 there is no scaling. normals r normal. any more ideas? Link to comment Share on other sites More sharing options...
siddharthkolte Posted January 28, 2015 Share Posted January 28, 2015 I think you must have already done this check but just in case you have not, check object properties... under visible to camera or renderable should be on. Link to comment Share on other sites More sharing options...
erkutacar Posted January 28, 2015 Author Share Posted January 28, 2015 lol yes actually those see-through parts in the image r not visible to camere so that i can get a 3d floor plan render but as u know iray is physcally correct so even if the object is invisible to camere, iray ignores it here is a mentalray render of the same geometry.

erkutacar Posted February 7, 2015 Author Share Posted February 7, 2015 anyone has any solution for this stupid problem? Link to comment Share on other sites More sharing options...
siddharthkolte Posted February 8, 2015 Share Posted February 8, 2015 Can you isolate this scene to only that room and share the file. I could test this using the same file as I am not able to replicate the issue here. Link to comment Share on other sites More sharing options...
erkutacar Posted February 10, 2015 Author Share Posted February 10, 2015 its very weird man, i thought it didnt support generic autodesk materials so i switched to a&d mats, the living room is fine now but when i change something, another object becomes invisible for instance i applied a&d mat to a desk in the bedroom, then it became visible. but the tv on the table became invisible. oh and tv's legs were visible so naturally i thought it was material issue and i applied override material from render dialog and applied a standard mat. now the tv was visible but the wardrobe doors were invisible im going insane it does the same thing with both ies lights and standard photometric lights and also with daylight only Link to comment Share on other sites More sharing options...
erkutacar Posted February 10, 2015 Author Share Posted February 10, 2015 visibility also differs by the camera angle. the dining table has 6 chairs, i just took a closer render and the middle chair got invisible this has nothing to do with the scene its an iray issue Link to comment Share on other sites More sharing options...
siddharthkolte Posted February 11, 2015 Share Posted February 11, 2015 (edited) That is bizzare... may be Iray is possessed... do a cleansing ritual(reinstall 3dsmax)... lol I tried recreating your issue but have absolutely no problems with my scenes. All work no probs. Please share your MAX file, really want to see this amazingness of iray... Edited February 11, 2015 by siddharthkolte Link to comment Share on other sites More sharing options...
erkutacar Posted February 11, 2015 Author Share Posted February 11, 2015 here is the download link http://www.arsmeatim.com/4A.zip Link to comment Share on other sites More sharing options...
siddharthkolte Posted February 11, 2015 Share Posted February 11, 2015 Except for missing textures there seems to be no problem with the meshes disappearing in the file you sent. So the problem is not the file, it is definitely something to do with 3dsmax or the GPU. Here is the Iray window on my PC. Link to comment Share on other sites More sharing options...
erkutacar Posted February 11, 2015 Author Share Posted February 11, 2015 i told u i fixed the sofa, there r half of the walls? where is the ceiling? did u disable them from layers?, do some renders in other parts, like the master bedroom Link to comment Share on other sites More sharing options...
erkutacar Posted February 11, 2015 Author Share Posted February 11, 2015 also try different angles and distances... Link to comment Share on other sites More sharing options...
siddharthkolte Posted February 11, 2015 Share Posted February 11, 2015 The walls/ceiling is not visible to camera in the object properties, I thought this was intentional... anyways if I override the materials to a white material everything works. I tried moving the camera as well no probs... Link to comment Share on other sites More sharing options...
erkutacar Posted February 11, 2015 Author Share Posted February 11, 2015 they r invisible to camera but that shouldnt work in iray, iray is physcal, it doesnt allow camera tricks.. what version of max r u using? Link to comment Share on other sites More sharing options...
erkutacar Posted February 11, 2015 Author Share Posted February 11, 2015 lol im so dumb, i didnt look at the version in the image well im using 2013, maybe they added some new features in urs Link to comment Share on other sites More sharing options...
Tom Sproule Posted February 15, 2015 Share Posted February 15, 2015 I was going to suggest checking the materials. We were rendering a scene in Mental ray last week and one of my accessories was invisible in the render. When I looked into it it had v-ray materials assigned instead of A&D. I had two versions of the accessory with different materials and put the wrong one in the scene. The weird thing was I had no error messages in the render.

erkutacar Posted February 18, 2015 Author Share Posted February 18, 2015 i dont have vray, all the materials r a&d and i unchecked backface culling. i started a new scene and it does the same thing everything is visible accept the walls im going crazy here.. i guess i need to format my system Link to comment Share on other sites More sharing options...
siddharthkolte Posted February 18, 2015 Share Posted February 18, 2015 Hey, I thought you still had problems with props, not the walls... the Walls and the ceiling is just not Visible to Camera under the Object Properties turn it on and try it... It should work... Link to comment Share on other sites More sharing options...
erkutacar Posted February 18, 2015 Author Share Posted February 18, 2015 iray ignores that because iray is physical.. and anyways only half of the wall was invisible to camera. i started a new file, whole wall object is visible to camera but it doesnt appear in the render Link to comment Share on other sites More sharing options...
