Is there a way to create custom meshes dynamically?

Like the procedural mesh in Unreal. Or the Arraymesh in Godot.
And how difficult/easy would it be to tack on my own render solution? Like my own render passes. I am familiars with OpenGL, Wgpu, and some Vulkan.

Hello,

Not currently, but you can definitely add it if you want.

• You can start from the Renderable component, since every entity that needs to be rendered has a Renderable:
  https://github.com/PanosK92/SpartanEngine/blob/master/runtime/World/Components/Renderable.h
• The Renderable holds a Mesh pointer.
• The Mesh uses an RHI_Buffer* for its vertex buffer, this is a good place to start.
• For dynamic meshes, you can create this buffer with usage flags like VK_BUFFER_USAGE_VERTEX_BUFFER_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT and memory properties suitable for frequent updates (HOST_VISIBLE for direct writes or a staging buffer for performance).
• You update the vertex data by writing into the buffer whenever the mesh changes.
• At this point you can expose this real-time update functionality in way that resembles other engines.

Hope this helps.
