@theonlymrcat:matrix.orgTheOnlyMrCatIt draws the shape in the expected spot, and forcing the alpha to one gives me a black square01:08:42
@kvark:matrix.orgkvarkif you force the output color to be red, does it render correctly red?01:11:39
@theonlymrcat:matrix.orgTheOnlyMrCatYes. I've also tested setting red and green to the x and y texture coordinates, and I get the correct result01:12:22
@kvark:matrix.orgkvark Can you run the quad example? It samples from a texture. 01:14:06
@theonlymrcat:matrix.orgTheOnlyMrCat It works on both the master and hal-0.7 branches 01:25:29
@kvark:matrix.orgkvarkok, so what are you doing differently? It would be most convenient to use GPU debugging tools and see. But you can also just try to reduce the case and see the differences01:26:22

@vivichrist:matrix.orgvivichristdoes gfx_hal::queue::Submission still exist?00:57:36
@kvark:matrix.orgkvarknope00:58:35
@vivichrist:matrix.orgvivichristOk I guess I'll learn WebGPU first since it has working tuts01:52:00

@csnewman:matrix.orgcsnewmanDoes gfx-rs support partially bound and unbounded/variable sized array descriptors? At an initial glance it doesn't appear so?20:18:09
@kvark:matrix.orgkvarkWhich vulkan extensions correspond to this?20:44:33

Which vulkan extensions correspond to this?
it's all DI

variable sized array we do UNSIZED_BINDING_ARRAY or whatever
21:07:19
@cwfitzgerald:matrix.orgcwfitzgeraldwe don't however support descriptorBindingPartiallyBound21:07:26
@cwfitzgerald:matrix.orgcwfitzgeraldI don't think21:09:41

@csnewman:matrix.orgcsnewmanHow much effort would it be to bring up DI? (Idk how well the features map to metal for example?)00:16:07
@kvark:matrix.orgkvarkI haven't investigated, but it might be possible with metal argument buffers00:34:57

Metal (with msl 2.0) deals with everything we currently expose except unsized bindings (and I think they fixed that in a recent spirv_cross) I get the impression that things like partial binding is also supported as msl is awfully "everything is just a pointer"-ey
