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”

Renderman Spline rendering

I’ve tested RenderMan with spline rendering. it’s much faster compared with baked Geometry. the spline primitives are very good in Renderman. I’ve stopped the test with mantra after 10 minutes, it is super slow even with optimized render settings. the Renderman images rendered for 3:20 on a 6 core Xeon 2.7ghz with pxr pathtracer. 4kContinue reading “Renderman Spline rendering”

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”

maya sprites rendertest in rendeman

its a simple render test of maya sprites in arnold and renderman Studio. it uses a simple noise pattern on a 2d ramp with 2d ramp displacement. one simple noise plugged into a ramp can give a really complex shading behaviour. the extreme displacement come from a simple ramp, this give the smoke more depth.Continue reading “maya sprites rendertest in rendeman”
