What's wrong with my set up, it just show a red screen

Vulkan
1

I’m modifying my render and now it goes totally wrong. Whatever I do to the fragment shader, it just stay in red.

I’ve tried renderdoc to find out what’s wrong, and I can’t even debug the fragment shader with renderdoc’s new debug feature.

It must me something wrong but I can’t find it, the previous version which is working fine, and it can be debugged with rd.

Can any body help me, please.

Here is the renderdoc file.

Hello there,

are you already using Vulkan validation layers?

best regards,

Yes, of course. But It shows nothing useful.

In renderdoc, there is 3 error about VK_EXT_debug_report, but my 1080ti device doesn’t support VK_EXT_debug_report. It must something wrong, so that renderdoc will trigger VK_EXT_debug_report, but I still have no clue.

I suspect why it shows red screen is because it writes the depth value directly to the color buffer.

Just a drive by comment, I’m afraid I don’t have an idea for your actual problem: It’s an instance extension (not a device extension) and should be supported, see e.g. this gpuinfo report.

Oh, that’s my mistake, I’ll try it if it can produce more info, thx.

6

Oh, I miss it again. It’s VK_EXT_debug_marker not VK_EXT_debug_report, what stupid I am.

Hey, guys. I’ve solved this problem. What I have done two things wrong.
The first mistake is the clearValue, this is actually a union, although it has color and depthStencil fields, they share the same memory.
My code is clearValue.color = {0.0f, 0.0f, 0.0f, 1.0f};clearValue.depthStencil = {1.0f, 0}; and this makes clearValue always red which is {1.0f, 0.0f, 0.0f, 0.0f}.
Second mistake is I didn’t move my camera, so it didn’t draw anything and that makes the fragment shader unable to debug. the Renderdoc pixel shader debugger must be used on a triggered fragment shader
