vraylightmtl

How do you crank up the multiplier on the vraylightmtl? Also is there a vrayhdri loader. How do people crank up the fstop value of hdri’s?

This one stumped me for a sec too. You can overdrive the number in the color picker past 1.0.

ahh okay thanks.

i suppose you can connect a multiply/devide node into the color and increase the amount there. Though vray material should contain its own multiplier.

intuitions method worked great. any idea about the hdri issue?

well, for hdr, you the way maya users do it, is control the brighteness with color gain, where you just lower or raise the value.

You load an HDR the same way you do a bitmap. You raise it the same way, through the color picker. As for F-stops, keep in mind that it is exponential.

+1 stop = x2
+2 stops = x4
+3 stops = x8
+4 stops = x16

-1 stop = 0.5
-2 stops = 0.25
-3 stops = 0.125

interesting. Im not at home at the moment, but I could have sworn, when I loaded the hdri map into the color slot, the color picker was no longer accesible. ill try again when i get home tonight.

well its the color gain of the actual hdri filenode.
