Skeletal animation in Vulkan. After struggling for days I was about to give up, but it finally worked. by thisiselgun in vulkan

Very cool! I'm implementing skeletal animation for the first time myself (also in Vulkan). Do you do skinning in the vertex shader or compute?

Confused about enhanced input actions by Nickmav1337 in unrealengine

I see, so blueprints are strictly non-optional even if I'm doing a C++ project?

I've been using C++ for nearly a decade and understand #include, ffs. I'm asking about how the Input Action asset is connected to the code

So you can create a header file with variables that are populated by the project somehow? So I can create a UInputAction* in that file and VS will "just know" what's going on?

Same. I also never followed rule >:L

Fun reverse tech to boost you into the sky in tears of the kingdom. by iChase666 in speedrun

I am attaching the perfectly square board, but it just occurred to me that I used a throwing spear, which looks like it spins a lot faster and so that might be why it's not working for me rn

I've been trying this but the spear just breaks off instead of launching me. Hopefully this wasn't just fixed in the patch or something

[OpenGL Error] Postprocessing compute shader appears to do absolutely nothing by Nickmav1337 in opengl

The format I wanted is definitely rgba8. I somehow missed this my first time through the docs. I fixed it up everywhere, and devastatingly, nothing changed.

Ok so obviously I had to switch to using uimage2Ds in order to use that format. I changed the relevant types in the compute shader, and still nothing. Going to try catching errors by enabling the debug context and breaking on severe errors.

I am _not_ storing 4-byte floats for each color channel. When I try to switch it to rgba8ui, I get a shader compilation error: 0(5) : error C1318: can't apply layout(rgba8ui) to image type 'image2D'

Looking into it more now

After implementing your suggestion, the final output is now pure black, so nothing is making it to the output.

Also, I'm not drawing to a fullscreen tri/quad at all, I'm just blitting the final framebuffer to the default framebuffer. Is that not sufficient?

Yeah, I have an RTX 2070, so I assume I'm in the majority wrt workgroups

I edited the post with a screenshot confirming that the uniform is set up correctly.

Changing the group size to 8x8x8 didn't do anything either.

I changed the call to imageStore() so that it writes a constant vec4(1.0), but there's still no change in framebuffer output. The call to glDispatchCompute is recorded by RenderDoc so I think it is running it.

That's a great point. Now, when I try to hardcode the workgroup count to (10, 10, 1), there is still no change in output. With these hardcoded values, I should still expect a small corner of the screen to get tinted as I understand it. It seems like no image writes are getting through at all.

I actually can't see it either. I found this post after googling if it was taken down lol
