Need a WHITE background in rendered image

[l_taylor2]

Hello all,

I have been pulling my hair out for the past 2hrs trying to produce a simple render of an AS structure using the sun and sky illumination and rendering either with mental ray or the basic Autocad rendering engine. What I cannot figure out is how to get the background in the rendered image to be anything except transparent. Everything else about the render is acceptable except that there is no background (in the autocad render window this shows as jet black, in a pdf or word file it shows as below).

How is this accomplished? I have tried every fix I can find on the knowledge base and forums and no dice. Plenty of success changing the viewport display. But nothing I do seems to change the background in the rendered window.

Any help would be amazing, I don't feel like this should be so hard, but either there is a major bug here or I am missing a setting somewhere.

Thanks!

Levi

Hi,

so I tried this AKN article, to see if it would work,  it save to create a new view, then edit the background settings on that settings dialog for the view.

https://knowledge.autodesk.com/support/autocad/learn-explore/caas/sfdcarticles/sfdcarticles/Changing...

the thing I noticed that even though in the model space to that custom view, my background was turned of under the visual style( I had done this on the model previously) when I turn it back on via visual styles it changed it to white 255,255,255

Then the render command , when set to in window it worked.

here's an screen shot:

Hmm, just tried that and it didn't work for me.

What image format are you rendering to? Mine is set to PNG and I wonder if there is a background transparency setting that I need to change. If there is I don't know where it is or how to access it.

Thanks.

The issue I found was that even if I set in under the new view created, when I then ran the render command, it came out black background.

But in the model space and the custom view, checking the visual styles , noticed that my backgrounds where turned off.

Changed this setting to background on, it then picked up the white setting for soild background. Running render again it created with said white not black.

Saving to png format.

Strange, my backgrounds are turned on in both places. Still get the black background. See screenshot.

Worth noting that if backgrounds are not turned on in the visual style my viewport background is the standard dark theme, not white. Background on in the visual style gives me that background in the viewport but not in the render.

Weird.

Thanks.

Did you create a custom view, found I had to follow that part to get it to work, took a few attempts to get it to work.

Cheers

Yes, I did. You can see the "test2" custom view in the view manager on the screenshot I attached in the previous post. It's looking more and more like a strange Autocad inconsistency.

Let me know if you think of anything else.

made a quick recording, showing what did on my side, just went back through the same process again.

Sorry but it doesn't look like the recording attached properly. Can you attach again?

Thanks!
