Hello D5 Render team, a little idea and personal request, i dont know if you are familiarized with the render software “Keyshot” it has an option to add a backplate on the scene, instead of seeing the HDRI we see an image backplate, its very helpful to make renders placed on an image, like for example a building render placed on its land. It would be very very helpful for me and pretty sure everyone else. Hope is not a big problem.
Thanks for the great work!
Received with thanks. We’ll consider adding this function to our roadmap.
BTW, the upcoming version of 1.8 has a material rendering option as “invisible in raytracing”. You could place a backdrop picture in the background while turning this option on, and the lighting will not be influenced. Do you think it will work in this case?
Thanks for feedback 
yes, that sounds perfect to cast shadows in a backplate and help to get the effect 
probably will help but I wonder how will it be to match the background image with the model perspective 
we will see. Thanks again.
Did you try importing a rectangular plane mesh with the background image applied? You can then move and scale it freely to match your scene?
yes =) ive done it several times, and it works but only when doing images inside the building/ design…when its about aereal perspective of a house/building it becomes extremly hard… attached an example of what you commented
I see what you mean. Nice renders by the way. 
I got what u mean…in that case the “backplate” option should still be needed…
=) yes, its very helpful for that kind of renders =D thanks again!
I realized that if you export images with channels. You’ll find one channel map named alpha (new feature since version 1.7), you could use this alpha channel to replace the background.
That’s one way, but the problem is we can’t show the accurate and proper reflection of it on reflective surfaces (glass, metal, and other small details), which is only possible if we have a
final background in the d5 software (before doing any post-production). It is like putting human figures and trees in photoshop and casting their shadow to make it look realistic, but it’s too much work. Now it is way easy, drag and drop the characters/ vegetation and the rendering software automatically gets all the small details (reflection, shadow, depth, etc). I hope you understood my point
Yes, but the big problem here is placing the rendered object in the right perspective so it matches the image
