Hey Houdini heroes,

In an (probably stupid) attempt at unifying my gamedev pipeline is it possible to simulate the Standard Shader (Unity 5) in Houdini SHOPs?

In Houdini I'm not sure how the parameters for Roughness (reflectivity) and Metallic (metal-ness) translate. The roughness parm on the Mantra Shader doesn't seem to work as expected and as to what ‘Metallic’ actually means is anyone's guess?!

Ideally i'd like to create a shader that is roughly comparable with the basic set-up in Substance Designer in PBR mode

All my tests in Houdini with PBR and an Env light seem to look poor in comparison to the real time PBR in Unity 5 / Substance Designer.

Could any shading guru give me any pointers as to where I should be looking (Blogs / videos etc) or which parms in SHOPs I should be investigating?

Many thanks,

Rick.

You might want to check out Wolfwood's Disney-style BRDF, http://forums.odforce.net/topic/20682-bsdf-bonanza-ggx-microfacets-disney-brdf-and-more/ [forums.odforce.net] - it has metallicity built in.

Fantastic!

Thanks eetu - i'll have a play around with these,

Much appreciated
