I am rendering a very simple scene formed by a cylindrical reflective surface and a floor. For rendering it I have also used a simple code (I have not used photonmapping although it is specific for caustics because I had problems, that I commented in other post Photon Mapping differences between two images, with that module ):
gensky -ang $elevation $azimuth +s > 01A-Luz$n.rad oconv 01A-Luz$n.rad 01B-Outside.rad 01C-Materiales.rad 00A-Fachada180.rad 00B-Suelo.rad > 02-Escena.oct rpict -i -vf 03-Vista.vf -x 4096 -y 4096 02-Escena.oct > ./Render/04-IImagen$azimuth-$elevation.hdr
When I look at the falsecolor image, everything seems normal but when I have analyzed the values, I have realized that those values seem to be limited in a range of values instead of been continuous.
If we zoom in on the graph, we can see that the jumps are about 10000 lux, except in some areas where intermediate values do appear. What could be the reason for this?
Thank you in advance.
