Join Brian Bradley for an in-depth discussion in this video Creating a mesh light, part of V-Ray 3.0 for 3ds Max Essential Training.
- In this video, we're going to take a look at the final operating mode of the V-RayLight, and demonstrate just how easy it is to turn a piece of scene geometry into a direct light source. To do this, let's come to the Layer Manager and un-hide the Spherical Mesh Lights layer, by clicking on the lightbulb icon. This just reveals a number of sphere objects that have been placed around the perimeter of our ornamental pool here. If I go ahead and, one at a time, select through these, we can see that they are just regular 3ds Max primitives with nothing added to them.
To turn these into V-Ray mesh lights, the first thing we will need to do is come over to the Create tab, jump into the V-RayLight section, and then click to select the V-RayLight button. As it really doesn't matter which operating type we work with at this moment in time, we can come over to the top viewport and then left mouse click and drag to create a standard V-Ray Plane light. Remembering of course to right click in order to exit Create mode. Jumping to the Modify tab, we can then come to the operating Type option and make the switch over to Mesh.
Of course this doesn't immediately create a mesh light in the scene, as there is one more very specific option that we need to make use of. To do this, we can come down to the Mesh light options and use the Pick mesh button. Once clicked, we can come into our scene and select the piece of geometry that we want to turn into a mesh light. The sphere on the far right here will make as good a starting point as any. Once done, we see that in the modify stack we still have access to all of the sphere's parametric controls, meaning we can re-size and alter it whenever we like, but we also have this set of V-RayLight controls that have been placed on top.
Now before we go ahead and take a test render, I just want to turn the rest of the spheres here into light sources as well. So let's unhide the V-RayLight's layer, and then one by one, using the process as we've just demonstrated it, turn each of the spheres into a mesh light. Once done, I want to open up the V-Ray Light Lister, as I want to take my test render here with the current key light, or sun, turned off. In fact, we would probably see the effect of these mesh lights much more clearly if we also opened up the Render Setup dialogue using the F10 key and then disabled GI as well.
When we take a render now, the only direct light sources contained in the scene are the V-Ray mesh lights that we have just created. And do keep in mind that all of the standard V-RayLight controls that we have already looked at in this chapter are available for use with these mesh light types. Now of course in this scene, we have only used a fairly simple piece of parametric geometry for our mesh light. But hopefully, we can easily imagine how, if using a more complex mesh, we could create some very cool, very interesting lighting effects using this particular operating mode of the V-RayLight.
