    Since 2021.2 has a support for VFX graph and high end devices I tried making a simple particle system which collides with a depth buffer. I'm using URP, forward renderer with Depth and Normal buffers. When I added Collide With Depth Buffer to Update all particles vanished and this keeps spamming in the console:

    Code (CSharp):
    1. Shader error in '[Sandstorm] [System] Update Particle': unrecognized identifier 'CameraBuffer' at kernel CSMain at Sandstorm.vfx(48) (on d3d11)
    2.  
    Code (CSharp):
    1. [Sandstorm] [System] Update Particle.compute: Kernel at index (0) is invalid
    Is this node not compatible with URP yet? Is there a list of URP compatibility somewhere?

    Hi!
    Blocks that require reading from camera buffers (Position(Depth), Collide with Depth Buffer, etc) are not compatible with URP yet.
    Normally those blocks would do nothing, but they should compile fine. That error message is a bug which is being fixed (not sure if it reached the latest version).

    Thanks for clarifying.

    Is there any documentation with a list of nodes which are / aren't compatible with URP as of today? I really want to use it in some capacity but right now I don't have the confidence nodes which I need are supported.

    For some reason there is no mention about comatability in docs and I am pretty sure there was before, strange... probably it was other node/page like this one.
    I think it would be helpful to add list of URP not compatible nodes on this page for example.

    Hi,
    Yes we are planning to support this on URP, we had to wait for URP team to make the missing functionalities before being able to use it in VFX Graph on our side. Our part of the work on this matter should start soon. We can't give clear vision on how would this release tho, but it is being worked on.

    Currently, we don't have it. I will see with documentation team if we can do something for this. I think the most probable option would be to specify on a feature doc page if this feature is limited to one SRP. Hopefully in the future, no feature would be limited to a specific SRP.

    Alignment of features between HDRP and URP is one of our main focus in the future: to make sure that you don't loose options from one pipeline to an other.

    Have a nice day!

    I would like to ask if there has been any improvement on this issue up to now. The feature in question is theoretically a very simple one

    Any progress on this? I think many people are waiting for collision with depth buffer.

    Edit: There was an update on the VFX Graph roadmap in January this year mentioning that this feature will be delayed: https://portal.productboard.com/uni...-access-to-urp-camera-depth-and-color-buffers
