Baffled:What am I overlooking?

[ctk111]

A little frustrated here. I'm picking back up on a project that I left a month or so ago. For some reason when I render, the color is coming out completely different than when I had left it and I'm not sure what's going on. I didn't overwrite the file with new settings and just in case I went back to earlier versions which are rendering out differently as well. The only thing telling me that my vray settings and my physical camera settings haven't changed are that the sky in both images are the same. If I adjust the color mapping the sky color changes as well, so this is what makes me think the vray settings haven't changed. Could there be a global setting in max that I'm overlooking? Any help is appreciated.

Have you changed an external file that is involved int he render? an hdri, a bitmap, an xref, anything that could have been used in another project?

Upgrade in any software? New vray version for example? Is effect background ticked in the colour mapping?

Other than that, I havnt a clue.

...are you working in float?

Thanks for the quick responces.

No external references, affect background is checked and not an upgraded version. I have an hdri in my material editor, but it's not active in the environment. I thought of using it, but never did.

I'm using gamma correction with the linear multiply setting and both multipliers set to 1 with gamma at 2.2

try rendering with your gamma set to 1, and see if that matches the original. if that doesn't correct it, make sure your gamma settings are still set proper in the preference dialog.

Yeah, I was playing with the color mapping settings and the closest I got to the original was if I changed the bright multiplier to .5. It was pretty close, but still not right and like I said when I adjust the color mapping it changes the vray sky. The sky is the only thing rendering the same in both images. That's what is so odd.

you didn't say if you upgraded from 1.47 to 1.5(1.49.xx or whatever) in between the initial renders.

 

also, is the Vray sun multiplier still at 1?

Sun is still at 1 and I didn't upgrade.

vray sky in environment?

[ctk111]

Still haven't solved this problem. Is there a global setting in max I might have checked by accident. When I turn off the gamma correction in the preferences my materials swatches in the editor look much closer to the results in my original image. However, when I render I still get the blown out image. I've checked my sun, camera and color map settings. Every adjustment effects the color of my vray sky background which leads me to believe that these settings haven't been changed since that's the only thing consistent between the two images. This is what makes me think it might be a setting in max that has changed.

Have you accidentally ticked exposure control in environment settings?

[ctk111]

Have you accidentally ticked exposure control in environment settings?

 

No, the exposure control isn't on. Thanks for the reply.

Seems like you have:

 

Same machine

Same windows

Same render engine version

Same render settings

Same scene materials

Same camera settings

Same sky settings

Same GI solution

Same environment settings

.........

What else is there? What other globals are there?

Is there anything in the Buffer thats on different settings?

Yeah, unfortunately that about sums it up. I just looked at the frame buffer and any adjustments made there changes the sky background, so I'm assuming it's the same.

[Tommy L]

In that case, I think youre best just working from where you are and accept whats gone is gone!

[ctk111]

Yeah, I agree. I gotta move on. Thanks for the help.

maybe too late, but in some versions of vray there was a bug where you could end up with 2 vraysuns in the scene. check that and kill off the extra one.
