Objects are not being batched together for rendering when they all share the same Light Probe Proxy Volume object

Graphics - General



Priority: 3Not yet prioritized for a release


Severity: 3Workaround is possible

Steps to reproduce:
1. Open user's attached project
2. Go to "LPPV test" and open "LPPV test" scene
3. Enter Playmode
4. Open Frame Debugger window and enable Frame Debug
5. Go to Camera.Render > Drawing > Render.OpaqueGeometry > RenderDeferred.GBuffer > Clear

Expected result: In the Frame Debugger there should be only one "Draw Mesh (instanced) instanced sphere" since the light probes are used.
Actual result: In the Frame Debugger there are "Draw Mesh instanced sphere" for every sphere in the scene

Reproducible with: 5.6.3p2, 2017.1.1f1, 2017.2.0b11, 2017.3.0a7

Note: If you stop the player, select all the 4 spheres, switch their "Mesh Renderer > Lighting > Light Probes" from 'Use Proxy Volume' to 'Off', hit play again, the Frame Debug will show just one "Draw Mesh (instanced) instanced sphere".
