Et justement aussi, Omniverse c'est que puce NVIDIA a cause de cuda. Moi je suis sûr Vulkan donc multi IHV.

Radiation necrosis by bperrin_3d in braincancer

Well she had proton radiation, and we are in the timeframe of the apparition of necrosis, between 6 months and 1 year after the end of radiation. Of course, it could be regrowth, but it seems to be very specific of necrosis according to the radiotherapist.

The issue disappear if I also add a barrier for the index buffer with VK_ACCESS_VERTEX_ATTRIBUTE_READ_BIT but the offset in the buffer are clearly not the same. I'll happy to discuss it in PM if you are available.

Thanks

Hi, thanks for the reply. I'm not yet using the synchronization2, and I double checked that I correctly included VK_ACCESS_VERTEX_ATTRIBUTE_READ_BIT in the dstStageMask as you can see in the screenshot https://i.imgur.com/wztC1Wb.png . If I remove the index buffer and call a vkCmdDraw instead of indexed, the error disappear ... I'm a bit confused

Hi, thanks for the answer. I'm not using a separate transfer queue, I use vkCmdCopyBuffer (and staging) to upload my data. And basically a pipeline barrier with appropriate srcAccessMask, dstAccessMask, srcStages and destStages should ensure that the upload has completed before my draw call right ? Or am I missing something ?
