Tips for producing cloud reflections in windows

[Christiaan]

I find it very difficult to get any substantive cloud reflections in windows when rendering.

 

Any tips?

It is in your Render Style > Background > Environment Reflections

where you can set a different Texture Map than what is seen by Camera or Environment Lighting.

Yeah done that, thanks, but it never creates enough cloud reflections for my liking. Nowhere near it.

The rest is material settings,

while physical glass being a dielectric with typical low reflection value of only about 4% but 100% fresnel,

will soon look not so physical if you increase reflection value at 0°.

So cloud reflections mainly when seen from the side.

 

Next can be to increase the contrast and brightness of the environment reflection texture used for reflection,

and finally faking in post production. (Where it it would be nice to render reflection masks at separate channel)

Are you suggesting settings here? 

[zoomer]

Yes and no.

I propose workarounds but am a physical based rendering evangelist.

And can't resist to palm my view of things off while answering questions

 

But important is that you reach the result that you want.

In many cases that does not mean to be realistic.

How about posting a sample pict of what you'd like to achieve and I may be able to tailor a file that will include custom materials and a rendering style?

Thanks zoomer, this solved my problem. I wish I'd understood it properly when you first posted it! 

 

I also made a wish relating to this:
