Layering images with canvases with shadows

Hurdy3D

Hey,

I have a complex images with lot of figures which is to big for the RAM of my GPU.

My plan was to seperate this image in layers and render these with canvases.

Basically this works fine. But the visible objects does not cast shadows of the invisible ones.

I did a simple example. Just a plane and sphere. On picture 01 you see both rendered. The sphere casts a shadow on the sphere.

Picture 2 is just the sphere. What I like to achive is that the png has the shadows of the invisile elements. Is this possible?

You need to create a matte for that object, basically add a plane under the igloo you have there, and add the My DAZ 3D Library > Scripts > Utilities > Create Advanced Iray Node Properties

in your parameters tab you now have an extra matte options. Now you can render the igloo and the plane (shadowcatcher) in your layer.

Thank you!

Basically it worked. But I'm not really happy with the result.

You see in the first image the original image, rendered with the plate and the sphere.

The second image are rendered both seprate and merged togeter in Affinity Photo. The shadow is much to dark :(

The shadowcatcher plane has its own material properties so be sure to copy them over. You could for instance just duplicate the original ground and matte that, you’d end up with the same materials.
