Objects cast shadows, recieve shadows, but not recieve self shadows.

Hi.
I want to create objetcts that cast shadows, recieve shadows but not recieve self shadows.
Further,those objects’ surface unaffected from lightings (just like unlit shader).
Is it possible?

Hi and welcome,

When you say “receives shadows but not receive self shadows”, that sounds a bit complicated to to me. So you want other objects shadows cast on the object, but the object can’t cast shadows on itself and it also has to be unlit so that no shading is happening except a flat color?

I can’t quickly suggest any ideas, and as far as I know disabled self-shadowing isn’t easy to do. You can find some discussions on the topic in threads such as this:

Having a GameObject not receiving is own shadow

Hi guys, I have an issue and i can't find the answer by myself : I want a Game object not to receive is own shadow but to cast one and to receive the shadows of others Game objects. Here's an example with Cast Shadows & Receive Shadows on : [image] And here's the visual result I want (Receive shadows is off) : [image] The problem is, the mesh doesn't receive is own shadow but neither it receives the shadows of others meshes ! [image] I did find a clumsy solution you can see below. I…

But if you need a flat/unlit material that just casts a shadow, you can find a few examples on the web, like this:

Hi, Olmi.
Thank you for your reply!

Yes, I know It’s complicated…
I read both of references but these aren’t suit for my situation.

I would be happy if you could tell me when you came up with a new idea.

Thanks.
