water rendering with arnold GPU

I am starting to look into water effects shading, this 1st simulation with Houdini solvers. the foam is a little over-the-top. but I think the shading itself starts to come together. with the new Arnold GPU updates it’s getting really fast., specifically when I am using Arnold Operators. I’ve created underwater bubbles in extra simulationContinue reading “water rendering with arnold GPU”

About Render Engines part 2

Each render algorithms has different benefit in different Scene / Light Situations.  Some common Render engines using following Algorithms: Here is list Pro and Con based on my own Experience :    Pathtracer Pro : easy to use best for exteriors great characters and outdoor renderings Con : bad for caustic not so good forContinue reading “About Render Engines part 2”

About Render Engines part 1

This is a quick overview of current render Engines for Houdini and General in terms of MotionGraphics and VFX usage.  There are different RenderEngines out there, each one is unique and uses different method to solve a problem. I am looking into Arnold, RenderMan, Vray, Octane and Redshift. For comparison reason I added Indigo RendererContinue reading “About Render Engines part 1”

marble rendertest

Inspired by great Marble renders and Shader hack by Lee Griggs. I’ve decided to recreate some tricks with different render engines, a little render Comparison. The basic idea, using a glass shader for outter shell and an inner sphere with textured volume to fake depth. this way, you will save a lots of work withContinue reading “marble rendertest”

light simulation

I’ve made a simple scene to test the physics of light. for proper light calculation, I used spectral render Indigo and Octane. Indigo has multiple Engines, standard Spectral Path tracer on CPU or GPU and Bidirectional path tracing with MTL sampling (metropolis Light Transport). Octane has only default Spectral Path tracer on GPU but includesContinue reading “light simulation”

Reference for vfx part 1

currently i am working on FX book. here a little sub chapter of it. To create special effects digital you don’t have to recreate or simulate physically correct like in real world. its not possible anyway. you do not need fancy, custom made solvers. in most cases you just need ordinary standard tools which everyContinue reading “Reference for vfx part 1”
