Question Lighting - how to creat a Matte shadow shader? (creat a shadow on a light baked imported object)

[TheDJin]

Hi community
before asking I've just want the community to all the contents tutorials and sharing.

I would like to know if it's possible to have a shadow matte shader in VAM.

to explain, a material shadow matte is a shader that we apply to an object. where the object will be transparent. except for the shadows. it will recieve the shadows but the object still transparent.

Indeed, I would like to use this shader if it exists to create shadow on unity assets imported with a baked light.

Because when I import a unity asset with a baked light, I don't have any shadow on it. And I thought of this solution to solve this problem.

Example:
I have a floor with a baked light on it.
the idea is to add a plane above the floor of a few millimeters in unity and apply a shadow map.
so in vam it will look like the floor is receiving the shadow.

good to know that i'm not an expert on unity, and i don't know how to do to have a shadow matte shader in unity too. ^^

Thank you in advance for all your help.

Unfortunately there is no custom shader support in VaM 1.x.
Maybe we will get one in the future 2.x version.
There are some ways to somehow inject advanced shadow-effects, but that is far above my horizon.

For your current shadow issue on custom unity assets, you maybe want to try out Nostage3's great "Unity-Asset-Vamifier" plugin.
This will add shadows even to some CUAs where the VaM lighting doesn't work.

You can also somehow bake in shadows with Unity or using ready made shadow maps on a CUA, or add one with a transparent plane.... but that would not affect VaM figures, of course.

thank you for your clear answer.

Yes, it's a sad that the VAM 1.X is so limited with lighting.
and I'm really looking forward to the 2.X. The latest video just released makes the wait even harder.
I just wonder how long it will take for the community to develop as much content as VAM 1.X.

Otherwise to come back to the subject, "Unity asset vamifier" is just a great plugin, and helps a lot. But what is sad with this plugin is that it removes the light baking. (my concern is that without lightbaking, there is no global illumination on a scene, wich makes it somehow better look).

But well, if there is no solution. I continue with what's in the box (and that's already a lot )

Thanks again.
