HDRI Background doesn’t show up on render

[Iliada]

It is the second time I have this issue. I apply on background the HDRI file for background, set it up for an amount from 30 - 50 as always did but when try to render the scene the background is white. Can someone please help?

Hi Iliada,

You should check the following:
- Decrease the exposure in the V-Ray Frame Buffer to make sure that the image is not just overbright


- Make sure that the HDR Bitmap texture placement is set to Environment Spherical


- If you're using a Dome light make sure that the light shape is set to Sphere


If this doesn't help, please share a simple scene example.
This way I'll be able to easily find the cause.

Hi, I am having the same problem, I have done the steps above still not a change. Not sure whether it matters that I am still using the trial version of SketchUp? I'll add a screenshot

Hi mariya_ivanova,

The trial version is not limited in any way.
Can you zip and share your test scene for further investigation?
You can also use the Pack Project feature from the V-Ray menu.

Hi,

Thanks for sharing the project.
The answer is really simple actually - spherical environments are not visible in Parallel Projection camera mode.
Changing the camera to perspective shows that your setup is correct:


If you want to see textured background in parallel view your only texture placement option is Screen:


And to be honest I wouldn't recommend that since you'll have to separate the texture visible in the background and the one used for lighting.
Screen projected textures produce incorrect lighting...

Hope that makes sense,
Konstantin
