Bindless Texture Modify Parameter after GetTextureHandle Broken(?)

OpenGL OpenGL: Advanced Coding
#1

I am (successfully) using bindless textures:

  1. Create Texture Object32
  2. Set params
  3. Allocate/Create Content (Depth_Component in my case)
  4. Get Handle64, Make Resident
  5. Attach To FrameBuffer
  6. (Use as regular Depth Buffer)
    So far so good:

However, once I have the handle64 (not even making the texture resident) I cannot modify the parameters of the original texture object.
It seems there is no way to release the Handle64.

The following post seems to have a similar problem, but could not solve the problem.

Did I overlook something or is the bindless stuff only half baked.

Best Regards.

It’s not “half-baked”; this is by design. You aren’t allowed to modify a texture object after you get a handle. Ever. Full Stop.

The better question would be why you are trying to modify the textures parameters? If you have some legitimate need for this, you can create a view texture of the original with its own set of texture parameters.
