Problems with cascaded shadow maps

[Dark_Photon]

@Rapoma

layout (set = 0, binding = 2) uniform UBO
{
  ...
  float vCascadeSplits[SHADOW_MAP_CASCADE_COUNT];
  ...
} ubo;

I was surprised because every float was allocated as vec4.

I fixed the problem declaring the cascade splits as …

  vec4 vCascadeSplits;

Now,the Cascade Shadow Maps implementation looks pretty well

You may be interested in:

• VK_KHR_uniform_buffer_standard_layout

which allows you to use the std430 layout on UBOs. Without it, I believe the default in Vulkan GLSL is std140. From GL_KHR_vulkan_glsl:

  The initial state of compilation is as if the following were declared:

    layout(std140, column_major) uniform;  // without push_constant
    layout(std430, column_major) buffer;

  However, when push_constant is declared, the default layout of the
  buffer will be std430. There is no method to globally set this default.
