Unigine chokes if too much is visible from initial camera position

[danni.coy]

We are having some issues with Unigine stalling at loading on very large levels. Changing the position and angle of the start camera currently seems to be a work around.

it seems \engine\render\direct3d10\framework\D3D10Shader.cpp line 676 and 640 have some problem,

if I change the code to

if(num_fragment_buffers) device->PSSetConstantBuffers(0,num_fragment_buffers,buffers);

 

engine load heaven in a much much faster speed.

 

the original code produce so many warnings without if(num_fragment_buffers)

This is very strange because Direct3D runtime shouldn't do any job in this case.

I have added such code into all D3D10/11 shaders.

if I just add those condition, there are still many info prompt in debug output of visual studio:
