Textures With Indirect Command Buffer

Question

I render with func drawIndexedPrimitives( type primitiveType: MTLPrimitiveType, indexType: MTLIndexType, indexBuffer: MTLBuffer, indexBufferOffset: Int, indirectBuffer: MTLBuffer, indirectBufferOffset: Int ), when I use Argument Buffer to set textures（e.g. to fragnent shader）, everything is fine. But is there a way to set textures without Argument Buffer? Argument Buffer is the only way?
When used with Argument Buffer, things go well.

No, there's no other way. If you are using indirect command buffers, you have to get textures through argument buffers.

If you look at the API on the CPU:

• MTLIndirectRenderCommand only has setVertexBuffer and setFragmentBuffer.
• MTLIndirectComputeCommand only has setKernelBuffer

and on the GPU:

• render_command only has set_vertex_bufer and set_fragment_buffer
• compute_command only has set_kernel_bufer.
