[Runtime Error]Micro-Mesh displacement not supported

[lyd405121]

Description

• Successfully build using cmake
• Run the Sample
• Failed when check vulkan extesion

More info

• windows10
• 2070 super

Background

• After reading serveral GTC reports， I really like this tech most
• Since the weakness for raytracing is handle with transparency and displament
• Moreover，parallel remesher is also what I am searching for

Glad you like the tech, thanks :). This error looks to be coming from mini_samples/dmm_displacement/src/dmm_raytrace.cpp

  if(!app->getContext()->hasDeviceExtension(VK_NV_DISPLACEMENT_MICROMAP_EXTENSION_NAME))
  {
    LOGE("ERROR: Micro-Mesh displacement not supported");
    exit(1);
  }

This would happen if the driver is missing VK_NV_displacement_micromap support. Can you try updating to the latest vulkan beta driver at https://developer.nvidia.com/vulkan-driver?

• Beta driver, Get it.

  Another question

• I notice that "VK_NV_displacement_micromap" is NV extension, so it can only be used with nvidia gpu.
• While the OMM SDK which I have already played for weeks, need VK_EXT_OPACITY_micromap imply this is a common extension.

• Is that right?

In theory other vendors could implement the extension as is, even if it is a vendor extension, but typically it needs a bit of a standardization process. Right now NVIDIA is the only vendor implementing it. Sites like vulkan.gpuinfo.org allow you to see what is available in the field.

Thank you for your kind imformation :)
