Vulkan SceneLoader Failing to load entire Scene

[icarolelis1]

Hi.
I have this strange situation, My scene loader is not capable of load the entire mesh array.
When I try to reduce the loop that call the draw command to something close to 70% of total mesh.size() it work’s fine.
I’ve tried different meshes and the same thing happens…

commandBuffers.resize(swapChainFramebuffers.size());

VkCommandBufferAllocateInfo allocInfo = {};
allocInfo.sType = VK_STRUCTURE_TYPE_COMMAND_BUFFER_ALLOCATE_INFO;
allocInfo.commandPool = commandPool;
allocInfo.level = VK_COMMAND_BUFFER_LEVEL_PRIMARY;
allocInfo.commandBufferCount = (uint32_t)commandBuffers.size();

if (vkAllocateCommandBuffers(device, &allocInfo, commandBuffers.data()) != VK_SUCCESS) {
	throw std::runtime_error("failed to allocate command buffers!");
}

for (size_t i = 0; i < commandBuffers.size(); i++) {
	VkCommandBufferBeginInfo beginInfo = {};
	beginInfo.sType = VK_STRUCTURE_TYPE_COMMAND_BUFFER_BEGIN_INFO;
	beginInfo.flags = VK_COMMAND_BUFFER_USAGE_SIMULTANEOUS_USE_BIT;

	if (vkBeginCommandBuffer(commandBuffers[i], &beginInfo) != VK_SUCCESS) {
		throw std::runtime_error("failed to begin recording command buffer!");
	}

	VkRenderPassBeginInfo renderPassInfo = {};
	renderPassInfo.sType = VK_STRUCTURE_TYPE_RENDER_PASS_BEGIN_INFO;
	renderPassInfo.renderPass = renderPass;
	renderPassInfo.framebuffer = swapChainFramebuffers[i];
	renderPassInfo.renderArea.offset = { 0, 0 };
	renderPassInfo.renderArea.extent = swapChainExtent;

	std::array<VkClearValue, 2> clearValues = {};
	clearValues[0].color = { .0f, 0.0f, 0.0f, 1.0f };
	clearValues[1].depthStencil = { 1.0f, 0 };

	renderPassInfo.clearValueCount = static_cast<uint32_t>(clearValues.size());
	renderPassInfo.pClearValues = clearValues.data();

	vkCmdBeginRenderPass(commandBuffers[i], &renderPassInfo, VK_SUBPASS_CONTENTS_INLINE);





	VkBuffer vertexBuffers[] = { vertexBuffer };
	VkDeviceSize offsets[1] = { 0 };

	
	vkCmdBindVertexBuffers(commandBuffers[i], 0, 1, vertexBuffers, offsets);
	vkCmdBindIndexBuffer(commandBuffers[i], indexBuffer, 0, VK_INDEX_TYPE_UINT32);

If I change the meshes.size in this loop, for something close to 70% of the meshes size it works fine…
In other words, I can render the latest meshes.
I’ve tried to render just the last meshe and the same thing happens

	for (size_t x = 0; x <meshes.size(); x++) {
		std::cout << "\n X :  " << x << std::endl;

		VkPipelineLayout pipeline;
		if (meshes[x].material->hasTexture) {
			pipeline = pipelineWithTexturelayout;
			std::array<VkDescriptorSet, 3> descriptorSets;

			descriptorSets[0] = descriptorSetScene;

			descriptorSets[1] = meshes[x].material->descriptorSet;

			descriptorSets[2] = LightdescriptorSetScene;
			vkCmdBindPipeline(commandBuffers[i], VK_PIPELINE_BIND_POINT_GRAPHICS, pipelineWithTexture);

			vkCmdBindDescriptorSets(commandBuffers[i], VK_PIPELINE_BIND_POINT_GRAPHICS, pipelineWithTexturelayout, 0, static_cast<uint32_t>(descriptorSets.size()), descriptorSets.data(), 0, NULL);

			
		}

		else {
			pipeline = pipelineTextureLessLayout;
			std::array<VkDescriptorSet, 2> descriptorSets;
			// Set 0: Scene descriptor set containing global matrices
			descriptorSets[0] = descriptorSetScene;
			descriptorSets[1] = LightdescriptorSetScene;
			// Set 1: Per-Material descriptor set containing bound images
			//descriptorSets[1] = meshes[x].material->descriptorSet;

			vkCmdBindPipeline(commandBuffers[i], VK_PIPELINE_BIND_POINT_GRAPHICS, pipelineTextureLess);

			vkCmdBindDescriptorSets(commandBuffers[i], VK_PIPELINE_BIND_POINT_GRAPHICS, pipelineTextureLessLayout, 0, static_cast<uint32_t>(descriptorSets.size()), descriptorSets.data(), 0, NULL);

			
		}


		vkCmdPushConstants(
			commandBuffers[i],
			pipeline,
			VK_SHADER_STAGE_FRAGMENT_BIT,
			0,
			sizeof(Materials),
			&meshes[x].material->properties);


		//vkCmdDrawIndexed(commandBuffers[i], static_cast<uint32_t>(meshes[x].indexCount), 1, 0, static_cast<uint32_t>(meshes[x].indexBase), 0);
			vkCmdDrawIndexed(commandBuffers[i], static_cast<uint32_t>(meshes[x].indexCount), 1, 0, static_cast<uint32_t>(meshes[x].indexBase), 0);

	}
	

	vkCmdEndRenderPass(commandBuffers[i]);

	if (vkEndCommandBuffer(commandBuffers[i]) != VK_SUCCESS) {
		throw std::runtime_error("failed to record command buffer!");
	}
}

When I try to load the entire scene i get an error in vkQueueSubmit it returns -4, wich I believe it’s VK_DEVICE_LOST

The problem was my VkCmdDrawIndexed call.

When i changed to vkCmdDrawIndexed(commandBuffers[i], meshes[x].indexCount, 1, static_cast<uint32_t>(meshes[x].indexBase),meshes[x].vertexOffset, 0);

considering the mehses vertex offset it worked.
