PhotoRendering completely blue please help!!

Jackcowdrey — Thu, 11 May 2023 09:51:03 GMT

Hi all,

I am having trouble with photorendering certain views that I have set up. Recently, for reasons I do not know why particular views I have set up and rendered a thousand times now appear blue and green in the viewpoint and when I render. Some of the views I have saved do this and some do not, I have gone through the settings of the ones that do this and the ones that don't meticulously and cannot find out what is causing this.

Has anyone come across this before and able to help?

Thanks

Hello Jackcowdrey

Your scene appears to be at night. The ambience I see looks like natural lighting at sunset, that would explain why the scene is blue.

I invite you to put an orange artificial light source in your scene to see if the color of this lighting will contrast with the general bluish atmosphere.

You could also check the emission colors of your surfaces.

I am ready to try your pln file to find the right solution.

Hi Christophe,

Thank you for your reply. I unfortunately won't be able to share the pln file. Could you please advise me on how I would go about adjusting the ambience, how to add an orange artificial light and how to check the emission colours of the surfaces used. Thanks

The problem is not so much the surface settings as the lighting settings of your render 'scene' and the time of day.

With cinerender you have the environment, physical sky, sun, extra lights, light emitting surfaces, reflectance etc etc that can all affect the colour of elements in your picture.

This is why Christophe asked for a file so he can quickly go over all these settings (I assume).

As it is, your question leaves a lot of guessing and assuming on the side of other users here.

Try using one of the out of the box preset scenes like 'outdoor daylight fast (physical). This should give a daytime view with very little interference from blue-ish tints due to dusk.

Hi all,

I tried rendering on the preset outdoor settings and I get the same blue screen! I pasted all the elements into an older model (not including lights) that I know renders fine, however once I have pasted in all the elements I am still getting the blue screen!

So it is something in the model that is making it do this?? Any ideas please this is driving me crazy!

There is no "skydome" that has accidentally been brought in has there?

No there is not. I forensically went through the file to see if there were any elements that was causing the blue render appearance, and once the paving element to the ground plane was deleted it renders fine! Very very weird as this ground plane has been in the model for months and never caused any issue...

Hi Christophe,

Please see my previous comment for what I think is the problem in regards to the blue screen. I cannot share the model with you unfortunately!

If you do a render with just the ground plane, does it still render blue? If so, you could just select the ground plane, then go File => External Content => Save Selection as Module => Uncheck "Replace Selection" => File - .pln. This should create a copy of the selected elements in a new file with the same template and attributes which you would then be able to share?
