TracePro crash at startup
Question When I launch TracePro, the program crashes (I observe a Runtime Error message). How do I get TracePro running again? Synopsis TracePro crash at Startup Solution "The possible causes of the problem differ if TracePro has run successfully on this PC for a period of time and then it...
Graphics problems when trying to view TracePro with NetMeeting
Question I understand that you have attempted to use NetMeeting with TracePro, but only the frame of the TracePro Window appears without any detail in the model window. Synopsis Graphics problems when trying to view TracePro with NetMeeting Solution This is a graphics issue, related to where the...
Cleanliness standards
Question When I attended the recent TracePro training course, there was mention of references that related surfaces cleanliness levels (specified by MIL-STD-1246C) to cleanroom classifications (specified by FED-209D).What I am looking for is research that was published on how to link MIL-STD-1246...
Smoothing - what degree of smoothing is appropriate?
Question As an inexperienced optical designer, I have little idea what degree of smoothing (i.e. what range of waist radii) is generally appropriate to provide the most realistic answers. I'm sure there's no one right answer, but are there any rules of thumb one can use to determine an appropriate...
Overlapping Object Errors with Grid Raytrace
Question "I have performed a Grid Raytrace in my model, and TracePro is reporting multiple "overlapping object" error messages. I have looked over the geometry, and there are several coincident surfaces, but no overlapping objects. What is causing these error messages, and how can this be...
Texture file fails to read
Question I edited a Texture file in Excel, saved it as a text file, then tried to use it in TracePro, but I get an error message that TracePro fails to read the Texture File. How can I resolve this? Synopsis Texture file fails to read Solution Open the Texture File in a Text Editor application...

Analysis results after cancelling raytrace
Question Would you please explain the coherence between the saved total lumens and the number of ray traced. It could give some problems when you use the file in a calculation program. (See attached file: halfrun.ies)(See attached file: fullrun.ies) Synopsis Analysis results after cancelling...
Scattered plus specular transmittance equals Fresnel transmission
Question I want to make a surface which has some scattered transmittance. So I made a Fresnel type surface with varing BTDF ratio. Comparing the ray tracing results of different BTDF ratios, I found all the results are the same. Please let me know how should I express the nature of the rough...
