[BUG] Rendering branch crashes in Vulkan

[PlasmaDev5]

Bug description:
There are many crashes when using the next effects in vulkan. Here is a list

• Bloom crash on startup - image provided
• Sharpen crash when used - crash in ezDescriptorSetPoolVulkan::UpdateDescriptorSet
• Chromatic Aberration crash when used before tonemapping - crash in ezDescriptorSetPoolVulkan::UpdateDescriptorSet
• Debanding crash when used - crash in ezDescriptorSetPoolVulkan::UpdateDescriptorSet

Screenshots:
Bloom crash on startup

Dev-branch commit hash:
All tested in rendering branch pre FXAA

Hi @PlasmaDev5, unless for the chromatic aberration pass it's really weird for me to see that all the other passes are broken on Vulkan, since I've only used the RHI to implement these passes... Maybe the use of compute shaders?

Can you please show me the stacktrace? I'm not able to use the Vulkan renderer on my computer, the renderer is not able to initialize properly, but I can use Vulkan in games and other engines... I didn't had a look at the reason since it's still in development by the EZ team.

For the Chromatic Aberration pass you should use it after the Tonemapping pass. I plan to update the Tonemapping pass to add more algorithms and also use a compute shader instead of a fragment shader. But for it to work now you can make a quick hack in the TonemapPass.cpp file at line 80 to change:

outputs[m_PinOutput.m_uiOutputIndex].SetAsRenderTarget(pColorInput->m_uiWidth, pColorInput->m_uiHeight, desc.m_Format);

By:

outputs[m_PinOutput.m_uiOutputIndex].SetAsRenderTarget(pColorInput->m_uiWidth, pColorInput->m_uiHeight, ezGALResourceFormat::RGBAHalf);

The Post FX passes in our current render pipeline looks like this:

I used it after tonemapping in DX11 and ended with a black screen.
I removed the MSAA stuff from the pass

If i go straight from Tonemapp to FramePass it all works correctly
if i go to any other of the new passes it ends with a black screen

Pulled latest, works in DX11. will give a breakdown of the vulkan issues in the coming days
