V-Ray selected rendering output overexposed

[Anonymous]

Hi,

Whenever I do selected rendering method, in the preview window it looks fine. However, when it saves the image, it saves over-exposed and highlight burnt, which basically ignores my setup. I have saved the global setting, exposure setting in VFB and vray preset, but it still doesn't work. It saves the images normally when I use no render mask. Is there any setting for selected rendering output I am missing?

Cheers,

Sarah

Hi 🙂

Unfortunately no, I never got to fix it. However, I do an alternative method, which works just like selected rendering. I basically just made the objects I still wanted to render lighting etc. in the background, but not appear by unticking Visible to Camera feature, found in Object Properties. I also tick Matte Object and make Alpha Contribution -1.0 in VRay Properties if an object is overlaying the selected object so it masks over the selected object. I do a lot of fabric renders in room sets and stuff, so I just overlay the png's in Photoshop over the original composition. This method really speeds it up 🙂

can you post a snap shot of an image ( preview windows as you said) and the final save image.

First, how are you saving the image??

are you using the VRay frame buffer for this?? or are you saving directly from frame buffer option? save as,  VRay raw image or separate passes??

or are you using 3d MAx default frame buffer??

also what are your settings on the color mapping area? are you saving color mapping and not gamma?

Usually, you should reset all the VRay values to default, then everything should work.

I am testing here I don't have that problem.

I can't screenshot as I use selected rendering at work. I save the images by 'Render' or Batch Render. If I press F9 and save it on VFB, it saves fine. However, if I save the images via 'Render' or Batch Render, it ignores my global settings I put on VFB, this only happens on selected / included rendering. After messing around on VFB settings, I found out that if I save the image with separate render channels, it actually saves with the VFB settings. I am still learning a lot of things about V-Ray... I have VFB enabled if that is what you mean? This happens with every new and current scenes.
