var allocateInfos = new DescriptorSetAllocateInfo[_resolution];
var setLayout = _setLayout;
for (int i = 0; i < _resolution; i++)
    allocateInfos[i] = new DescriptorSetAllocateInfo(descriptorPool: _descriptorPool,
        descriptorSetCount: _resolution, pSetLayouts: &setLayout);
_vk.AllocateDescriptorSets(_device, allocateInfos, _descriptorSets).ThrowCode();
allocateInfos = null;

var allocateInfos = new DescriptorSetAllocateInfo[_resolution];
var setLayout = _setLayout;
for (int i = 0; i < _resolution; i++)
    allocateInfos[i] = new DescriptorSetAllocateInfo(descriptorPool: _descriptorPool,
        descriptorSetCount: _resolution, pSetLayouts: &setLayout);
_vk.AllocateDescriptorSets(_device, allocateInfos, _descriptorSets).ThrowCode();
allocateInfos = null;

why would this code not work? Validation layers say pAllocateInfos->pSetLayouts is VK_NULL_HANDLE

note that validation layers don't complain everywhere, just pAllocateInfo->pSetLayouts[4] and up up until 15, then it AVEs

yeah that should work fine

Deleted UserOP•4y ago

well I thought so as well 😛

wait

Deleted UserOP•4y ago

oh I noticed it I pass _resolution * _resolution allocs wups

Perksey•4y ago

yup

descriptorSetCount: _resolution

this smelt funny

I did only notice cause I F12ed into the bindings and noticed _descriptorSets [Count] is computed via descriptorSetCount oh wait but SetLayouts is an array again fuckin hell
