Have only just found your page and HOLY CRAP! I have been struggling to find good new resources that can improve my skillset with Redshift and these short form explainer videos are just the ticket! Will be bookmarking and coming back weekly to see what other brilliant tutes you have in the future. CAN NOT THANK YOU ENOUGH!!!!

[@renderbaron]

You´re welcome! :-) Next video will be on Wednesday, 15th Nov.! For a lot more other publications check this: www.renderbaron.de/publications.html

Man I love your voice over on these vids really easy to understand and follow, congratulations :)

[@renderbaron]

:-D Thanks man!

[@AA-fs5uy]

You really are doing gods work, genuinly couldnt find better short videos getting into the details of redshift than the ones you provide!!! Thank you so much!!

[@renderbaron]

Thank you! Trying to nail down question and answer as compact as possible :-)

[@GrumpNL]

Mind blown... again.

Mööp:)

[@margoyle6742]

Finally some decent explanation! Thanks a lot! But One question still remains: what are some Real-world Representations for Metalness Values below 1? Why would one gradually reduce it in the first place?🤔

[@renderbaron]

An example would be a greyscale texture map controlling the Metalness, e.g. for partially corroded or painted metals. But in this case me I´d rather use the Material Blender Node or stack multiple material tags.

[@margoyle6742]

@renderbaron Ah, OK Thanks! Still, this strikes me to be more like an On-and-Off Situation, than a smooth blending, but I get it. I would also use the MatBlender in that case.

Hi. Can you tell how to properly connect reflection/specular map of PBR material in Redshift standard material? When i connect specular map in to reflection color, it almost completely disable all reflections.I feel like I'm missing something.

[@renderbaron]

If you´re using the Specular Workflow you should plug the map rather to Reflection Weight than to Reflection Color. :-)

[@peacefulman2196]

@@renderbaron Strange. Reflection weight and color provides the same amount of reflection. Still very weak reflection compared to original material preview from website. Maybe some texture conversion needed? Its free pbr material from cgaxis.

[@renderbaron]

@@peacefulman2196Did you check, that the texture node has color space set to „Raw“?

[@peacefulman2196]

@@renderbaron Its substance material node, cannot find texture color space for reflection. When using extracted texture, yes, raw gives better reflection. Thank you.

[@antoniopepe]

I never noticed this node. When was introduced? 😂🔥

[@renderbaron]

I guess at the latest with the Standard Material Node, as this doesn´t provide the IOR Advanced mode of the Material Node.
