// We are currently supporting two different SSS mode: Jimenez (with 2-Gaussian profile) and Disney
// We have added the ability to switch between each other for subsurface scattering, but for transmittance this is more tricky as we need to add
// shader variant for forward, gbuffer and deferred shader. We want to avoid this.
// So for transmittance we use Disney profile formulation (that we know is more correct) in both case, and in the case of Jimenez we hack the parameters with 2-Gaussian parameters (Ideally we should fit but haven't find good fit) so it approximately match.
// Note: Jimenez SSS is in cm unit whereas Disney is in mm unit making an inconsistency here to compare model side by side
// TODO: Find a correct place to bind these material textures
// We have to bind the material specific global parameters in this mode

// TODO: Currently it is not yet possible to use this feature, we need to provide previousPositionCS to the vertex shader as part of Attribute for GBuffer pass
// TODO: How to enable this feature only on mesh that effectively require it like skinned and moving mesh (other can be done with depth reprojection. But TAA can be an issue)
// TODO: It is not possible to use VelocityInGBuffer feature yet. This feature allow to render motion vectors during Gbuffer pass. However Unity have limitation today that forbid to do that.
// 1) Currently previousPositionCS is provide to the vertex shader with a hard coded NORMAL semantic (in the vertex declaration - See MeshRenderingData.cpp "pSecondaryFormat = gMotionVectorRenderFormat.GetVertexFormat();") mean it will overwrite the normal
// 2) All current available semantic (see ShaderChannelMask) are used in our Lit shader. Mean just changing the semantic is not enough, Unity need to unlock other Texcoord semantic
// 3) When this is solve (i.e move previousPositionCS to a free attribute semantic), Unity only support one pSecondaryFormat. Mean if we ahve a vertex color instance stream and motion vector, motion vector will overwrite vertex color stream. See MeshRenderingData.cpp
// All this could be fix we a new Mesh API not ready yet. Note that this feature only affect animated mesh (vertex or skin) as others use depth reprojection.
// TODO: not working yet, waiting for UINT16 RT format support
