parameter pDescriptorWrites[0].descriptorCount must be greater than 0. The Vulkan spec states: descriptorCount must be greater than 0

Full error:

ERROR OCCURRED: Validation Error: [ VUID-VkWriteDescriptorSet-descriptorCount-arraylength ] Object 0: handle = 0x1a27e678e80, type = VK_OBJECT_TYPE_DEVICE; | MessageID = 0x110c6099 | vkUpdateDescriptorSets: parameter pDescriptorWrites[0].descriptorCount must be greater than 0. The Vulkan spec states: descriptorCount must be greater than 0 (https://vulkan.lunarg.com/doc/view/1.3.216.0/windows/1.3-extensions/vkspec.html#VUID-VkWriteDescriptorSet-descriptorCount-arraylength)

The solution is to set .descriptorCount(1) in DescriptorSet.kt (or DescriptorSet.java, both have this bug) in updateDescriptorBuffer() and updateDescriptorImageBuffer().

Then the sample world renders fine :)

• except when you leave the region of the ocean
• except when you go under water
• except from the FPS, only the first digit is correctly shown
• I get tons of validation errors, of the type

and with VK_IMAGE_LAYOUT_UNDEFINED at the end.
