is it possible to create a shadow catcher material? i think it can be very useful in architectural insertions, object presentations in a composite photo.
Shadow catcher material

Tudor Schinagel So you want to build the needed geometry and assign the shadow material, export a shadow map and overlay it in a composite photo.
=>That's an interesting request! I've forwarded it to our developers. -

I'm interested in a shadow catcher material too. I know it from Octane. The result is like at the attached PNG - the transparency is controlled by the shadow intensity. So, finally only a photo needs to be placed at a layer behind. The shadow catcher is a simple material option.

Sounds Good mate!
Also will be nice if we can take material ID maps from the renderings it will be easier for the post production, I think this option doesn't exist at the moment.
Best,

I think this is importance function for final touch with Photoshop.

+++ Yes !!
it is a quite common and a so very convenient feature in many other renderers -

Hello,
When using an environment provided by an HDRI skybox in ENSCAPE, how to render the shadows cast in this environment ??
Escape does not allow rendering with drop shadows in such an environment, and unlike other renderers, there are no special so-called Shadow Catcher materials to achieve the desired result.
The only simple method I have found to simulate shadow catcher effects, while waiting for this facility to appear soon in Enscape, is the one I share below:
Here is my workflow to achieve this shadow catcher effect.
1 - In SketchUp, place a large ground plane (without applying any material to it) which will be able to receive and contain all the shadows in the model.
He will later act as a "Shadow Catcher"
2 - Hide this ground plane in the scene.
3 - Make a first rendering of the scene. The shadows of the model will not be cast in the environment in this rendering.
3 - Reveal the previously hidden ground plane.
4 - In Enscape settings, in the "Visual Parameters", in the "Main" tab, change the default "None" style to "White" and in the "Sky" tab, tick "White Background"
5 - Make a second rendering with this white settings.
And finally In post-production in Photoshop:
6 - Open the first rendering without shading and then place linked above this layer in a new layer the second white rendering with shading
7 - Switch this layer to "Multiply" blend mode
And Voilà ! You've got it.
You can now adjust and reduce the hardness of the shadows by adjusting the opacity of the layer, or increase the hardness by duplicating this layer and again playing with the opacity of this new layer.
Herewith these phases in images applied to an example (Cast shadows of a car on the road in an HDRI urban environment background)

That's a really great workaround, thanks so much for sharing your insight.
Would you mind also posting this into a new thread in our "Tips, Tricks & Tutorials" section? This way even more users will be able to see your guide.

Hello Demian,
This is not a problem for me.
But to avoid the redundancy of the posts, isn't it easier from your side to simply move my post to the "Tips, Tricks & Tutorials "section ?
