Render to file not showing background color

[overkill4]

Hi all,

Working on a rendering in Photoworks, and I'm running into an issue while rendering to file. I have a grey background with a shadow floor which shows up fine in my test renderings on the screen.

Once I render to a Tiff file the background is now white with shadows. Why is my background color being ignored?

Or should I just render to screen and then take a screenshot to save my image as a Tiff? Will I lose quality that way?

Thanks in advance.

60% of the time, it works every time.

My only guess to this is that because TIFF is a format that has a "clear" background, you might be losing your background during the rendering to this particular format. Check for any options (such as "save alpha channel) and try checking one way and the other to eliminate the problem. Also, does this happen if saving to a JPEG or PNG (PNG also has a clear alpha channel background option)? If it's clear with JPEG, my guess is there's a problem with your installation (or missed option). If it's clear with PNG, it's almost certainly a missed alpha channel option at the time of saving the file.

I am having a very vauge guess that You might be loosing the background colour due to the light being too bright.
But it is only apparent with "High Quality" option in the Render to file command. As you background is only grey so that seems quite easy to be faded by light.

I have seen the difference between the screen & jpeg output but not very big differences.

Hope this helps.

It's the tiff file as Jeff Said. Your background should be there if you play with some PhotoShop settings to ingnore the alpha of the tiff. Save your image as a jpeg or bmp file, these don't have the alpha or transparencey like tiff or png formats. You could also just uncheck the "Save Alpha" box when saving your tiff files, as Jeff mentions.
