Question Decals, some idea to get the same result without Decal?

Hi!

I am facing so many problems with decals that I dont know more what to do.
I am using decals to simulate soft shadows on the base of some object.


But as another persons in the forum, when I change the camera position and depending the angle, decals just desappear.

In the image above is working very well. I move the Decal to almost in the middle of the object and choose the layers to a specific only for decals. Working very well in editor because in Android this is the result:


if a move to a very near distance from the floor so the decals just desapear in Android.

Do you have some sugestion to get something similar like it? Is a non static object because I need to move it.

I did it fallowing this tutorial:

Worked very well in editor but again, in Android doesnt worked. When in transparent mode in material, the decal just is not renderized.

I am using:


Thank you!!!

 

I dont know if help, but the decals desapear when the camera angle in Y change. Like looking from front and move the camera to the top. The camera is a Cinemechine in Orbit woth a target that is the object. So the camera is always looking to the object.

When we a closer to the floor the decals is showed but when we go rising in some time the decal will disapear.

 

Here one sample to show whats happens.
