Vray and epws


Does v-ray affect any energy or daylight simulations done in grasshopper? From my searching on google it seems vray purely for aesthetic reasons?

I ask this because I notice that in vray, sun light window you can set the location (with the default being the equator line that is over africa), Im concerned if this overrides the epw I import into grasshopper or they have no relevance to each other.


Hi -

You are not saying what you are doing with that epw file, but, most likely, the render settings have no influence on what you are doing in Grasshopper.


Thanks for the reply!

I was just importing an epw through file path for some solar gains and thermal comfort analysis of a zone. As long as vray has not override my weather data then all is good.
