on_before_execute()

bool MayaFlux::Buffers::SDFMeshProcessor::on_before_execute ( Portal::Graphics::CommandBufferID  cmd_id, const std::shared_ptr< VKBuffer > &  buffer  )

overrideprotectedvirtual

Called before each process callback.

Parameters

cmd	Command buffer
buffer	Currently processing buffer

Returns

True to proceed with execution, false to skip

Override to update push constants or dynamic descriptors.
