Vulkan vertex from again peeking by means of

I’m making an attempt to render a .obj mannequin with Vulkan 1.4. The thing is rotated with a quaternion over time. The "entrance" geometry of the mannequin is rendered as anticipated, however when the mannequin rotates and reveals the again, some components of the geometry from the entrance is peeking by means of the mannequin. I’ve tried a mannequin with a texture, and the again of the mannequin appears clear.

The VkPipeline i’ve setup comply with the one within the depth buffering code from the Khronos Vulkan-tutorial 1

VkPipelineShaderStageCreateInfo shader_stages[info->shader_count];
for (size_t i = 0; i < info->shader_count; ++i)  VK_COLOR_COMPONENT_G_BIT

};

const VkDynamicState dynamic_states[] = {

    .dynamicStateCount = ARRAY_SIZE(dynamic_states),
    .pDynamicStates = dynamic_states,
};

const VkPipelineRenderingCreateInfo rendering = {
    .sType = VK_STRUCTURE_TYPE_PIPELINE_RENDERING_CREATE_INFO,
    .colorAttachmentCount = 1,
    .pColorAttachmentFormats = &info->shade,

    .pDynamicState = &dynamic_state,
    .format = pipeline->format,
    .renderPass = NULL,
    .basePipelineHandle = VK_NULL_HANDLE,
};

The color attachment is utilizing the format VK_FORMAT_R8G8B8A8_SRGB and the depth VK_FORMAT_D32_SFLOAT when rendering with VkRenderingInfo.

Right here is the entrance of a colored Suzanne, you’ll be able to see the ear showing by means of the face on the correct

And the again, with the geometry from the face peeking by means of.
