Nsight Graphics 和 RenderDoc 无法跟踪应用程序

我被困在写一个Vulkan渲染器。我在屏幕上看到的最终输出只是透明的颜色，随着时间的推移而动画，但没有几何形状。即使所有可能的验证都打开了，我也不会出现任何错误 /警告 /最佳执行 /性能提示等，除了最好的practices警告：“您正在使用vk_pipeline_stage_all_commands_bit当Vkqueuesubmit称为vk_pipeline_stage_all_commands_bit”。实际上，不确定我使用所有可能的验证，但是我在“ vk_layer_khronos_validation”下运行了所有复选框，然后勾选了所有复选框，此后，vkqueuesubmit提示

在戳了几个小时后出现了几个小时，我决定使用renderdoc，我可以启动应用程序，我可以启动该应用程序。很好，但是renderdoc说“连接状态：建立，API：无”，我无法捕获框架。

我以为我会考虑使用Nsight图形只是为了找到相同的问题：我可以运行该应用程序，但它说“可连接的过程被检测到。状态：没有图形API”。我在某个地方阅读我可以先启动该过程，然后使用附件功能将附加到运行过程中，不幸的是，我阅读的结果与

我阅读的结果相同时可能会出现问题，这可能是我的，这是我的原因要随着时间的推移改变透明的色彩，以确保我实际上呈现每个框架，我可以确定

我在这一点上已经失去了这种情况，有人是否有类似的经历？关于我可以做些什么来使RenderDoc / Nsight图形正常工作？他们俩都没有在日志中显示任何内容，因为我猜他们只是假设该过程不使用任何图形API，因此不会追踪。

我还感谢您为什么看不到几何形状的想法，但我知道这甚至很难从您的身边猜测，还有一些笔记：我什至已经强迫深度和模具测试了，尽管顶点应该是counter_clockwise，但我也检查了一下顺时针为了确保，设置脸部剔除模式，检查颜色写面具和rasterizerDiscard，甚至设置gl_position忽略顶点位置并完全转换矩阵，并在范围-1到1中使用一些随机值，基本上是所有内容当我听到“只有透明颜色，但没有错误”时，我就想到，但是

如果一切都会有所帮助，一切都没有用：我使用RTX3070或Intel UHD 770都在Win11上，两者都有相同的结果

小型更新： 使用Vulkan配置器，我可以在上面强制VK_LAYER_RENDERDOC_CAPTURE层，然后在运行应用程序时，我可以看到覆盖层，然后按F12后，请阅读该框架捕获了帧。但是，renderdoc仍然找不到此过程的图形API，我不知道如何访问该捕获

，然后强制vk_layer_lunarg_api_dump上的vk_layer_lunarg_api_dump并将其倒入我检查过的HTML中，我仍然看不到任何错误。我特别仔细观察了管道和RenderPass创建电话。这让我认为这将是任何统一 /顶点缓冲区内容 /偏移量或其他任何东西，因此我删除了其中的任何一个，使用硬编码的顶点位置和片段输出，而且我仍然只能在屏幕上的最终图像中看到清晰的颜色。

谢谢

I am stuck writing a Vulkan renderer. The final output I see on the screen is only the clear color, animated over time, but no geometries. Even with all possible validation turned on I dont get any errors / warnings / bestPractices / performance hints etc except for the bestPractices warning "You are using VK_PIPELINE_STAGE_ALL_COMMANDS_BIT when vkQueueSubmit is called". Not actually sure I use all possible validation, but I have Vulkan Configuration running and ticked all checkboxes under "VK_LAYER_KHRONOS_validation", after which the vkQueueSubmit hint showed up

After poking around for some hours I decided to look into using RenderDoc and I can startup the application just fine, however RenderDoc says "Connection status: Established, Api: none" and I cannot capture a frame.

Quite confused I thought I would look into using NSight Graphics just to find the same problem: I can run the application but it says "Attachable process detected. Status: No Graphics API". I read somewhere I can start the process first, then use the attach functionality to attach to the running process, which I did, unfortunately with the same outcome

I read there can be problems when not properly presenting every frame, which was the reason for me to change the clear color over time to make sure I actually present every frame, which I can confirm is the case

I am quite lost at this point, did anyone make similar experiences? Any ideas as to what I could do to get RenderDoc / NSight Graphics working properly? They both dont show anything in the logs as I guess they just assume the process does not use any graphics api and thus wont be traced.

I am also thankful for ideas about why I cannot see my geometries but I understand this is even harder to guess from your side, still some notes: I have even forced depth and stencil tests off, although the vertices should be COUNTER_CLOCKWISE I have also checked CLOCKWISE just to make sure, set the face cull mode off, checked the color write mask and rasterizerDiscard, even set the gl_Position to ignore the vertex positions and transform matrices completely and use some random values in range -1 to 1 instead, basically everything that came to my mind when I hear "only clear color, but no errors" but everything to no avail

In case it helps with anything: I am on Win11 using either RTX3070 or Intel UHD 770 both with the same outcome

Small Update:
Using the Vulkan Configurator I could force the VK_LAYER_RENDERDOC_capture layer on, after which when running the application I can see the overlay and after pressing F12 read that it captured a frame. However RenderDoc still cannot find a graphics api for this process and I have no idea how to access that capture

I then forced VK_LAYER_LUNARG_api_dump on and dumped it into an html which I inspected and I still cannot see anything wrong. I looked especially closely at the Pipeline and Renderpass creation calls.
This left me thinking it would be any uniform / vertex buffer content / offsets or whatever so I removed any of that, use hardcoded vertex positions and fragment outputs and still I can only see the clear color in the final image on the screen.

Thanks
