I have followed the README_MoltenVK_UserGuide.md: pulled the modified VulkanSamples, opened the Demos workspace, selected the target Triangle-macOS and built it. I got a PBXCp Error:

BTW, while Vulkan community is nagging about apple not supporting vulkan, I appreciate Molten bridging metal and vulkan. It paves a way for both the frameworks to compare and get in sync with each other.

Sorry to hear you are having trouble.

Did you follow the instructions in the Installation section of the README_MoltenVK_Demos.md document…including retrieving the brenwill version of the LunarG demos (not the LunarG version), and making the required change to the symbolic link to the VulkanSamples directory?

[necktwi]

Yes! I have pulled the modified samples from GitHub. Replaced the place holder symbolic links to these folders with the actual ones.

[necktwi]

To be sure I did it right, I’ve done again

cd ~/workspace
rm -rf VulkanSamples/
git clone https://github.com/brenwill/VulkanSamples.git
cd Molten-0.13.0/MoltenVK/Demos/LunarG-VulkanSamples/
rm VulkanSamples
ln -s ~/workspace/VulkanSamples/ VulkanSamples
cd ~/workspace/
rm -rf Vulkan-Samples/
git clone --depth=1 https://github.com/brenwill/Vulkan-Samples.git
cd Molten-0.13.0/MoltenVK/Demos/Khronos-Vulkan-Samples/
rm Vulkan-Samples
ln -s ~/workspace/Vulkan-Samples/ Vulkan-Samples

All are running good except the Demos in LunarG-VulkanSamples. I love that hologram one. And why there is no Demos folder in Khronos-Vulkan-Samples, as I see it should point to Khronos Vulkan-Samples?

I couldn’t witness the fish tornado because

I’m not sure why you are having trouble with the Triangle and Cube demos in VulkanSamples. I’ve just tried downloading Molten and VulkanSamples, as you have, and it builds and runs fine.

The error is happening within Xcode’s built-in copy operation. Perhaps have a look at the files within the Xcode Copy Bundle Resources Build Phase, and verify that Xcode has permissions to the VulkanSamples folder.

Regarding the Cinder demo, unfortunately, it is not yet publicly available. We are working to get it released through the Cinder team.
