V-Ray Dome, what a powerful tool

V-Ray Dome is an IBL tool, that means it has a lot of interesting features: it works with and without global illumination, it offers a lot of controls on the maps and this is not all! It is also optimized, faster and finally offer better results.

All the techniques we have in 5SRW Course are perfectly applicable to this tool, considering is primary or secondary light is not a problem. The focus is always finding the right place for this light into our ligh hierarchy.

CONCEPTS :

  • Use HDRI maps through VRayDomes, using the HDRI node
  • To get sharp shadows use HDRI maps with a clear spot light
  • Enabling “Store wih IM” corresponds to using HDRI in Environment rollout (F10)
  • Portal and Simple could be used to reduce render time, losing some details
  • In case of splatches created by portals, increase VRayDome samples to 30-50
  • Create Matte Objects enabling: Matte – Matte for refl/refr – Shadows
  • Enable Spherical (full dome) option when using HDRI with sky and ground
  • Avoid GI splotches disabling GI (in general or for the single matte object)
  • Disable GI when secondary bounces have no impact in the scene
  • Let perspectives match using Ground Projection
  • Ground projection only works for Environment maps
  • Use Radius and Position to tune the projection

(*) Lesson realized using 3ds Max 2014 / V-Ray 3.00.07, slight differences could appear with other versions

 

UNWRAP MATERIAL
In case you want to create a Matte Object using a material, you can use the VRayMtlWrapper, setting the same options you watched in the video. Remember that this material works only with a VRayMtl inside:
