For Shadow Catcher in EEVEE we use the trick (attachment pic). But in Verge it doesn’t work.

I also am looking for a good solution for this. The application example “simple configurator” has a system that kind of does this; but it seems to be a clunky workaround. It uses a large half hemisphere to encapsulate the scene. I have not figured out how to control the scene space color (sky, background, etc.), the way I would using the shadow catcher method.

You can check out my EEVEE setup in the attachments.

@Yuri

Is this something that could be evaluated and implemented? I want to build a whole series of content with ground shadows and a seamless background color; meaning no horizon or gradient detectable.

We added node Shader to RGB to our TODO list. It’s all what you need to implement ‘Shadow Catcher’?

Thank you Mikhail. Is there a maintained list in documentation that lists which nodes are currently supported? This would be so helpful; and would get you better feedback on people requesting support for specific things.

Without the that; I would question you regarding the setup I have had been using as my shadow catcher:

RGB to BW
Gamma
Gradient Texture

(See first image in my first reply; to see if you spot any other nodes not currently supported.)

Looking forward to having this working!

Hi,

We just issued the 2.12.1 maintenance release with Shader to RGB node supported. You can try the first-mentioned node setup and see if it works for you.

All this nodes already supported, so your shader must work the same as in EEVEE.

Awesome. Thanks Mikhail. I will give 2.12.1 a try and see how it turns out.

I believe the difference between my setup and the person who started this; is that mine gives additional flexibility in how the shadow renders. For instance you can make it fade as it gets further from the object; but control how much.

Hi,

Did anyone manage to use the EEVEE shadow catcher in Verge3D in the end?
I just tried, using the setup from the first post, but it’s not working. The object is still visible.

Hi,

check out the demo called Augmented Reality in the Verge3D installation folder. In that demo the character casts shadow to a transparent plane.

One option is to fake shadows. If all you need is a small faded oval, then you just make that as an image.

You can find a working example of shadow catcher in AR demo (only for blender and max for now).
