Help! PBR shader Transparent.

[fiatwiriya]

Hi I have a bit problem with transparent.

-The object in the front can see through the object from behind at some angle even alpha is set to 1( it’s suppose to be like 2 picture)
-The main thing is I try to make texture fade away base on world position. So the farther away the lower the alpha.

• Both objects share the same material
• I use URP. Uniy 2020.1.12f1

Not sure what I did wrong. Thank you so much for any helps.

You did nothing wrong. Correct and efficient sorting of real-time transparency is an unsolved problem.

This is working as expected. Efficient, and correct sorting of 3d transparency in real time rendering is still an unsolved problem. There have been a number of attempts to fix this or mitigate it, but they all come with a fairly significant performance hit. The way any single model is rendered is each polygon of a model is rendered in the order they exist in the model's definition. In the case of opaque or cutout each polygon writes to the depth buffer. Each new polygon drawn will test again…

There are some tricks to make this better, but literally none of those options exist for the URP when using Shader Graph. Your “best” option is to use dither opacity instead of real transparency.
