The resource binding were missing from the shading group (`shgroup->uniform_attrs`), leading to no custom property UBO creation (`drw_uniform_attrs_pool_update`) when issuing the drawcall, resulting in a missing UBO bind. The fix make sure to no duplicate the bindings by creating a simple shader bind instead of a `GPUMaterial` bind. Candidate for 3.2.1 corrective release.

/* Quick breakdown of the Volumetric rendering:
|
|
*
|
|
* The rendering is separated in 4 stages:
|
|
*
|
|
* - Material Parameters : we collect volume properties of
|
|
* all participating media in the scene and store them in
|
|
* a 3D texture aligned with the 3D frustum.
|
|
* This is done in 2 passes, one that clear the texture
|
|
* and/or evaluate the world volumes, and the 2nd one that
|
|
* additively render object volumes.
|
|
*
|
|
* - Light Scattering : the volume properties then are sampled
|
|
* and light scattering is evaluated for each cell of the
|
|
* volume texture. Temporal super-sampling (if enabled) occurs here.
|
|
*
|
|
* - Volume Integration : the scattered light and extinction is
|
|
* integrated (accumulated) along the view-rays. The result is stored
|
|
* for every cell in another texture.
|
|
*
|
|
* - Full-screen Resolve : From the previous stage, we get two
|
|
* 3D textures that contains integrated scattered light and extinction
|
|
* for "every" positions in the frustum. We only need to sample
|
|
* them and blend the scene color with those factors. This also
|
|
* work for alpha blended materials.
