Vray HDRI Backplate Problem.

[vikneshvijayakumar]

Hi,

 

I am learning 3ds max. Recently made an interior scene lit wit HDRI. This was my setup. Vray dome light with HDRI map loaded for reflection. Used the same hdri as environment. This was my result.

 

But, I didn't like the background and so wanted to change that with a random city image. I replaced the environment map with a bitmap. Added the bitmap to a material slot and made as environment screen. Then I instanced that back to the environment map. This was my result.

 

The render was a weird looking, transparent image. No idea what's the problem. What am I doing wrong? What is the correct way to set a backplate with hdri?

When you use the Reflection override as a "screen" type, it gets treated as a direct overlay and makes the scene look like this.

 

I would just use 2 dome lights and reflections off on one and diffuse off on the other.
