MeshBatch causes exception in forward rendering

[10c8]

Trying to use a MeshBatch to do GPU instancing in forward rendering leads to the following exception on line 276 of heaps/h3d/pass/ShaderManager.hx:

Missing param value h3d.shader.Shadow.Batch_Buffer2

Simply enabling the PBR pipeline like so seemingly fixes the issue:

h3d.mat.MaterialSetup.current = new h3d.mat.PbrMaterialSetup();

Is there a reason why PBR is necessary for instancing, or is that just a bug?

[10c8]

Note: This is observed in the latest stable version (1.10.0).

I think we fixed that on master.
