Recommended Posts

Hi everyone. I'm trying to render an exterior scene using Vray advanced, but when I render the image I get these unproper edges/shadows and cuts in the image. I have attatched an image of what it looks like, and what it's supposed to look like (the second image was rendered without vray). If anyone knows why this is happening, and/or how to fix it, please help me out

 

thank you all for ur time

i turned off default lighting, and added UVW map to all the objects that are having this problem. but i still seem to be getting those weird splotches. i added an image of the settings im using, maybe that's the problem.

 

can anyone help please and thank you

CHG, if you haven't seem this problem caused by Vray, then waht software did you see this happen with??

 

and does anyone think that maybe this is cause by the maps being one sided, and the light coming from behind cause those weird shadows??, maybe if i made them 2 sided maps it may work? i will try it tomorrow and render it, hopefully that's it, or maybe someone has a better idea? :(:confused:

not sure i have ever seen those before, they do look like uvw or coplanar face errors as previosly mentioned. i just meant that i have never seen vray produce that type of splotch. typically vray splotches are from poor irradiance settings, which tend to look like they had a splotchy cloud filter applied to them or from material overbright errors, which tend to look like warhol attacked your image by paiting red yellow blue and green circles everywhere.

well my huntch was correct, once i applied 2-sided maps, the problem seemed to disapear... except on the window lites, they still seem to be doin the weird light/dark shadow splotch thingy

 

thanks for all you help everyone, i really appreciate it. i think i will try and figure this last part out myself or just photoshop it out. thanks again.

Just as a matter note, I would recommend to most people to always try to model in the package you are rendering in. I know a lot has been done to try to better the pipeline between Autocad and MAX, and I am sure that a lot of it has improved. But I have always found that the pipeline between FormZ and MAX has traditionally been problematic.

christopher, are you on the Max subscription plan?

Perhaps if you apply the cap holes modifier to the lites

or

if you are using AutoCAD, export the lite separetly using the Command: 3dsout. Import the lites.3ds and hide the old lites group/layer in Max.

 

I had a similar problem and i found that those two solutions worked
