VRayLightMtl examples Home Render params VRayLightMtl
Example 1: Default Color and Multiplier values
Example 2: Higher Multipliers / 2-sided On and Of f
Example 3: Texmap
Example 1: Default Color and Multiplier values
Here is a scene rendered with the default VRayLightMtl. These examples demonstrate howmaterial behaves in V-Ray, and how its parameters influence the overlook of the final results.
The white plane is adefault VRayLightMtl.The teapot is a defaultVRayMtl with Reflection.
Rest is just VRayMtl withdiffuse colors.
Default Lights - Of f .Multiplier : 1 .0
No GI , No lights
Multiplier: 50 . 0
No GI , No lights

____________________
We are going to renderthis scene with DefaultLights - Of f till the endof the example and nolights will be used in itas well.
____________________
As you see the image isabsolutely dark exceptthe plane(self-illuminated) andthe reflection on theteapot. Notice we have
no GI and no lights at allhere, so the dark part of the scene is totalyexpected andreasonable.
____________________
Notice that nothingchanged in general, BUTthe reflection on theteapot got stronger dueto higher multiplier. Restis still black: because we
still have the GI o f f .
________________
As You see turninon almost didn't chthe overlook. Thabecause of Multiplier value: 1.It acts mainly as
self-illuminatingobject that hasVRayLightMtl.

____________________Now You can notice thatincreasing theMultiplier hasinfluenced visibly thescene (shadows also
appears).
____________________Scene starting to gathermore light because of the 2-sided - on .
____________________As You see the back isstill dark, but You canalready notice the bluewall receiving some GI ,due to higher
Multiplier . Shadow alsoappears more defined.
________________Scene starting to gmore light becausthe 2-sided - on .we also start tosome burnt areas dL inear type of Cmapping.

____________________So, increasing theMultiplier affects the GImore (we have morelight). But You can alsonotice that our render is
quite splotchy.
____________________Scene starting to gathermore light because of the 2-sided - on . Stillsplotchy GI solution.
____________________Comparing this result tothe previous is muchbetter. GI solution isclearer and shadows aremore precise. Of course
this leads to higherrender time.
________________Comparing this resuthe previous isbetter. GI solutioclearer and shadowmore precise. Of c
this leads to hrender time.
Example 3: Texmap
This example shows using the Texmap slot and how the map determines the Color parameter.
Multiplier: 3 .0
GI on ; 2-sided on
IR: HSphS: 1 0 0
IR: Interp.S: 4 0
Exponential ____________________
Using a Bitmap in theTexmap Slot. Multiplier

Increasing theMultiplier leads to
much lighter overlook of
