Optix Prime renders incorrectly (black) on Titan V (Volta).. about lighthouse2

[jbikker]

I found the problem.
While cleaning up the optixprime_b core for release I went a little too far. In pathtracer.cu you will find the shadeKernel function, and on line 55 the following statement:

const float4 T4 = pathLength == 1 ? make_float4( 1 ) : pathStateData[jobIndex * 2 + 0]; // path thoughput rgb

Replace this by

const float4 T4 = pathStateData[jobIndex * 2 + 0]; // path thoughput rgb

to make the core work as intended.

Sorry for making you search for a solution!

I pushed a fix, and included your improved Volta detection ('>=700').
