In opengl it is possible to clear some bits in the stencil buffer and keep other bits unchanged when I call
glStencilMask(mask ); before glClearStencil(0); glClear(GL_STENCIL_BUFFER_BIT);
In Vulkan when I have a stencil buffer with some pixels = 0x80
vkCmdSetStencilWriteMask with a mask = 0x7f vkCmdClearAttachment with clearvalue = 0,
then each bit will be cleared to 0. It seems, that the stencil write mask is ignored.
The last bounded pipeline has
VK_DYNAMIC_STATE_STENCIL_WRITE_MASK enabled, but
I’m not sure, that
vkCmdSetStencilWriteMask works only for draw commands or also for
Is it possible to clear only specified bits in the stencil buffer in Vulkan similarly to opengl, without a draw command ?
