Hi!
My new sideFX Houdini tutorial is out, see that rather as a documentation that can help you move from one renderer to an other within Houdini, or simply get the shading fundamentals of some of the best rendering engine !
Showing the same process with each one of them :
02:20 : Material Builder / base Shader - Mantra / Renderman / Vray / Redshift
04:40 : Geometry Parameters - Mantra / Renderman / Vray / Redshift
06:07 : Displacement workflow / Mantra-Karma
07:26 : Displacement workflow / Renderman
09:09 : Displacement workflow / Vray
10:54 : Displacement workflow / Redshift
12:46 : Textures with UDIM / Mantra - Karma
13:30 : Textures with UDIM / Renderman
14:21 : Textures with UDIM / Vray
15:15 : Textures with UDIM / Redshift
15:45 : Correcting & Mixing Textures / Mantra - Karma
17:42 : Correcting & Mixing Textures / Renderman
19:26 : Correcting & Mixing Textures / Vray
23:40 : Correcting & Mixing Textures / Redshift
25:16 : Layer Shaders with Attributes / attribute setup
25:42 : Layer Shaders with Attributes / Mantra - Karma
29:36 : Layer Shaders with Attributes / Renderman
31:59 : Layer Shaders with Attributes / Vray
34:53 : Layer Shaders with Attributes / Redshift
Not here to argue which one is the best or the fastest, not even trying to make something "pretty"... Just wanted to bring some insights to help you "translate" either my tutorials or any others.
By the end you'll probably realize they are all working the same. So don't focus learning on one tool but its general workflow. Then you'll be able to adapt your skills with ANY renderer.
