When loading an OBJ with a large index range, I encounter the following error. Could you suggest a solution?

Validation Error: [ VUID-vkCmdDrawIndexed-robustBufferAccess2-07825 ] Object 0: handle = 0xa4324a00000001c5, type = VK_OBJECT_TYPE_BUFFER; | MessageID = 0x41363e42 | vkCmdDrawIndexed(): index size (4) * (firstIndex (0) + indexCount (10000)) + binding offset (0) = an ending offset of 40000 bytes, which is greater than the index buffer size (24000). The Vulkan spec states: If robustBufferAccess2 is not enabled, (indexSize {times} (firstIndex + indexCount) + offset) must be less than or equal to the size of the bound index buffer, with indexSize being based on the type specified by indexType, where the index buffer, indexType, and offset are specified via vkCmdBindIndexBuffer

I’ll have a look into this

Not been able to reproduce this. Is it for one specific obj?
