Hi
I often use a plain light grey background with a shadow catcher material plane to create a catalog like render of a product. A plain background with shadow from the product.
For lightning I use a HDRI and if necessary an extra corona light.
With this method you reduce rendertime, beceause there is less background to render.
As far as I can remember I didn't had any problems with this method before v1.5. But now when I add a corona light the shadow catcher plane gets darker than the background.
If the corona light is turned off the transition from background to shadow catcher plane is smooth.
In the attachment my scene.
Does somebody know a solution?
Tnx

I have noticed this in my renderings as well! i was waiting for someone to post this.
The shadow catcher plane becomes visible when you tweak the "light mixer" settings of one of your lights. I have noticed it most when I the tweak environmental light. You might want to disable or set back to default. I think this could be a nice bug to fix for corona team! :)

Could you attach simple scene where this happening, i've tried to replicate that, but without success.

Attached a simple scene.
I noticed that with some HDRI's the effects it a lot stronger and with some the transition to the background is smooth.
So also attached a HDRI where I have the effect, light, buts it's there.
