Hi, I am struggling with the override background option in Vray Render settings. I loaded an HDRI map in the Override Background slot, adjusted exposure, and checked the scene’s real HDRI map as invisible. It all works OK in the Viewport, but I just rendered the production render and when saved I noticed, that Override Map did not save in the final image, but as a transparent - alpha channel. How to set the scene so that the Override background will not render as alpha but will be seen on the backround?
Hello @lukas_kostka
Is it correct to understand that you can see the correct background in the VFB but when saved it is transparent?
Are you by any chance saving your files in .png format? Saving your renders in .png format will lead to a Transparent Background. Try .jpeg or .exr.
Hello Viktor, Thank you. You are right, I saved as png. That could be it, didn’t think of that! Thanks..
I am happy it has been resolved, @lukas_kostka
Enjoy your time with V-Ray!
Hello @lukas_kostka
Please, send us your scene so we can investigate further. You can do that by Submitting a Request or sending it here.
Please, make sure to include all the HDRIs, assets and textures that might be needed.
Hello, @viktor_angelov , thank you, here is the link to the scene, both HDRI and the scene seem to be too large to send. I used HDRI from the link below but tested more of them. On interactive render, only black color shows, on production render, some weird colors on the background. Thank you.
Hello @lukas_kostka
First of all make sure to have all of your lights set to invisible.
Second, be aware that the Background might be darker if you have a Physical camera enabled. This is because the exposure of the image is controlled by the Physical exposure controls or the Exposure value in the V-Ray Physical camera settings. The camera exposure affects all parts of the render, including the background object.
There are two things you can add to your workflow to complete achieve what you aim for:
1. Add the Beauty Render Elements. Render the image. Add an Exposer layer to the Background Channel and increase its value. Please, find the video recording useful: http://ftp.chaosgroup.com/support/scenes/Cinema\_4D\_2023-08-17\_11-56-44.mp4
OR
2. Go to the Render Settings > V-Ray > Overrides > Environment > Override Background, Click on the texture that you have added to the tab and edit it in the Attributes menu. I have recorded a video for this workflow as well: http://ftp.chaosgroup.com/support/scenes/Cinema\_4D\_2023-08-17\_12-00-02.mp4
Please, let me know if you have further questions.
Thank you, @viktor_angelov .. I will try all of that.
Great @lukas_kostka Please, let me know how it goes.
