Closed wiltchamberian closed 2 years ago

wiltchamberian commented 2 years ago

on my win7 x64 pc , with the Vulkan SDK 1.2.162.1 with Visual Studio 2019 Debug x64 when I run the ray_tracing_ao demo, it crash at: void HelloVulkan::createCompPipelines() VkResult res = vkCreateComputePipelines(m_device, {}, 1, &cpCreateInfo, nullptr, &m_compPipeline);

in this function ,it crashes.

Hi yao tang!

I've just verified that the latest version should work (my system has Vulkan SDK 1.2.189 and NV driver 471.55) - could you give me more information about the system you're running on and the crash? Specifically,

Thanks!

@wiltchamberian, it works also for me, but I'm also using 1.2.189.0 and a very recent video driver. The graphic card is GeForce RTX 3060 Ti, which is supporting VK_KHR_ray_query. If you have all of the above and still fails, check if the shader is compiled and loaded one line above.

  cpCreateInfo.stage = nvvk::createShaderStageInfo(m_device, nvh::loadFile("spv/ao.comp.spv", true, defaultSearchPaths, true),
                                                   VK_SHADER_STAGE_COMPUTE_BIT);
