Bug Attempting to bind Texture ID as UAV, the texture wasn't created with the UAV usage flag set!

Hi,

happens after initializing a serialized RT and use a compute shader during the Serialization 2.0 convert, I think.

Code (CSharp):

1.         int baseKernel = Compute.FindKernel("CopyBase");
2.  
3.         // ... Attempting to bind Texture ID xxx as UAV, the texture wasn't created with the UAV usage flag set!
4.         Compute.SetTexture(baseKernel, "AmbientRT", RT_0);
5.  

The solution was to completely re-new all used RT_0 = new RenderTexture(....);
Can not reproduce the issue after this fix.

 

I'm also experiencing this bug. Could you help me understand your fix? Thanks you very much!

 

new RenderTexture via code, and set enableRandomWrite=true can work.

 

Sorry for the late reply.

Normally you can use a simple checkmate sniped to initialize an RT by
If (RT==default) RT = new RenderTexture(...);
The serialization process knows about the RT declaration and stores the RT initialization.
As long as the RT is not default the RT will not being renewed.

Now with the update process of the serialization system 2.0, the RT was updated into a new internal version with any missing ID reference, (or what every they do internally)

So when calling If (RT==default) RT = new RenderTexture(...); in the new version of Unity Ser. 2 ,
RT stays != default.
The computeshader.set... compares the new serialization 2 properties with some old fragments from the previous serialization 1 fragments.

If you force a renew by a temporal:
RT.Release(); If (RT==default) RT = new RenderTexture(...);
It's simply fixed in my case.
