VFB Issue

[JNoy]

Hi all,

 

I'm having trouble with a high-res image rendering. When I go above try to render at 3600x1800, the vray frame buffer starts rendering strangely and ultimately just gives me a black image.

 

I uploaded an image of what it looks like as it renders. I had already saved a light cache and irradiance map at a lower resolution. The image renders fine at 1200x600, so I'm wondering if there's an issue with the VFB being unable to stretch the IR/LC maps, or simply being unable to handle a higher resolution. If I don't render to the VFB, there is no problem.

 

Anyone else having this issue? Seeing those weird multicolor pixels is odd.

 

Thanks.

i have had similar problems, but i think the problem was that i had things in the scene imported from autocad.

 

to get around it i did new scene > xref objects > grab everything you know is good geometry. also go through your material browser and get rid of any non-vray materials (like raytrace)

 

dont know if this will work for you or not, but, there it is.

Hi Dave,

 

I tried xref scene and xref objects, but still got the error.

 

I completely merged all objects into a new scene and it was able to render at the larger resolution. I suppose that at some point the file was just corrupted, or some other weird glitch occurred.

 

Thanks for your suggestion!

I've had this problem before also... a while back now, could be wrong but seem to remember the VFB rendering black but when it automatically saved the image on completion it was correct?? could be wrong tho it was a while back
