Patreon Tutorial #38 - Transmission & Caustics - Part 2 (Patreon)

In this second part of our Patreon Tutorial #38 we will continue where we left off using the concepts we picked up from part 1. We will now be using more objects with out our example scene and further developing the materials and lighting. I will also use a quick RBD Bullet Sim to scatter some objects around.

Eventually we move to shading and how the roughness of a surface in particular has a great impact on the look of the caustics generated from the object. Towards the end I go over framing our shot using shadows and how our object distance from the light and surface affects our penumbra which is also how our caustics get influenced. Finally I go over how we can export and cache out our Photon Caustic Map and Irradiance Point Cloud GI to quickly re-use the cache while we adjust samples for our final render without having to re-calculate the Caustics.

Thanks again guys for all the support, have a great day!
