Overexposed render

[3DSetout]

Hi Showcase Peoples

Re Overexposed render in showcase when ‘publish image’

Using TIFF only the background is bleached out. The parts render fine.

Using TIFF hdr everything is bleached out

Using JPG renders well.

the scene looks good on the screen, but the rendered image looks bad.

Any ideas. thanks MatB

Could you send some examples and the setting you uses for publishing Images?
Thanks

Thanks garimberti

Turns out that i had to save and place my own XML into the

Documents\Autodesk Showcase 2014\InteractiveRaytracingSettings folder

I didn’t think i did that before.

I thought it was an option for the experienced.

But is it in fact the correct way

to get the fastest renders of different views?

Thanks MatB

did you render multiple images or just one?
do you have bloom effect activated?

Hey cikho. Thanks for the reply.

However, if u know something regarding Multiple Vs Single Images, or Blooming, please share it.

Otherwise, transferring the XML file seems the easiest solution. . but i am no egg-splurt.

Thanks MatB

If you can, upload some exaples, some screenshots are enough, about images with the problem and some screenshot of the publish images panel with the settings you use.

This can help us to understand the problem.

Thanks

Thanks garimberti



This is the TIFF hdr, and TIFF without my XML transferred



This is a JPG without my XML transfered which works fine



And this is the TIFF hdr result with my xml. . all good now





I do not change settings. I work with the standards offered.

I am after the most efficient, repeatable standard workflows.

And it seems saving and transferring XML is a good start.

Hi,

I have not seen any images of your project so it's hard to understand the issue really. 

The main problem might be how you are looking at the rendered image once it is rendered. For example, windows viewer will no display HDRI image properly and will not show the background image for the.tiff if it has an alpha channel.. so it might look washed out, where in fact, it's not being displayed properly. If the JPG is showing find, I can almost garanty that the viewer is the problem. 

If you are loading your HDRI image in a software (such as photoshop) which supports and can read HDRI image properly, I am sure it will be fine. Same for .TIFF images. You can load your .TIFF image in this free sofware to see it: https://pixlr.com/editor/

I normally save my final images as .Tiff, PNG or JPG and I get the same result.  The only reason why I use the .XML is to re-used the rendering settings. You don't need to do that if you don't need the settings.

it happened to me a few times that using multiple image saves, with bloom active, and having the sp4 installed caused overxposed renders.. but honestlyi can't remember which was the case, i have to investigate my old files

The floor is a real object or is the environment floor?

whath softare you use to open the final tiff image?

Try the render without the ADD ALPHA flag in the publish image setup.

Bye

Hi,

Yes, as I am saying, the background is not being displayed because you are rendering a .tiff image with an alpha channel. I am pretty sure that if you render the same image as JPG you will be fine. The background is there but not displayed properly in the image viewer. 

I get the same result  here and it's normal:
