Object from imported CAD file not visible unless it is selected (Color Property issue)
Question Opening a STEP file, the object is not visible unless it is selected, and after a while, I determined that the object appears white against the white TracePro background, so I changed the color. I am not sure whether this is on purpose or not, but I have to select all surfaces to change...
Changing File Source units between Radiometric and Photometric
Question "I generated a ray file using ProSource 5.2 and inserted a source into TracePro. Everything looks reasonable, I just have a question regarding units: The ProSource file shows a peak intensity of 0.26 Candela while TracePro gives 0.24 W/sr as the peak intensity on the Iso-Candela plot. If I...

Flux of Surface Source is controlled by 3 variables.
Question If a source which has a specific spectral profile is used for raytracing, how is the power, in FC or in lumen whichever, in each wavelength calculated? I'd like to know the relation between the weighting of each wavelength in RaytraceOption/Wavelength and the set flux power on...
