Hi everyone! Let me know if you have any questions about normal or displacement maps in the comments below! :)

[@alexnelson206]

It would be awesome if you could do a tutorial detailing how to edit materials with roughness to have rough, bumpy edges as opposed to straight! I know different programs likely need different tutorials, but if I was able to pick which ones you did a tutorial for I would choose SketchUp for the modeling portion and Unreal Engine for the rendering portion. Thank you for everything you do, you're a great help!

Hey, great video, but I'm using Vary 6, so any chance that you do the same showing how to use it in Vray?

Hello, I want to upgrade my current laptop with a new one. What graphics card should I look for, for rendering, Nvidia RTX 3060 is efficient or should I look for RTX A2000 (quadro)?

[@eastudio-K]

this is a good topic, I still use "Materialize" (from your previous video) sometimes, but still not that good at this

[@maximo_SA]

You are the best. Thanks you

[@aneeshkulathunkal7388]

Hello brother, while starting enscape for intrior renderinh ma wall showing too much brighting like whitenig. its very disturbing, how to fix this? and please kindly do a tutorial for basic render setting for a bignners like me .

[@aneeshkulathunkal7388]

please make enscape basic render settings tutorial for interior render and exterior render.

I've never really looked into the different maps, I just use displacement by default 🤭. Sometimes I end up downloading AO maps, but I have less than no idea what they are!

[@SkillipEvolver]

Yeah .. the problem I have is that if I were to explain the differences, I would struggle. Even though Justin explained it pretty well. ... I would still not really know when to use each type of map. It's clear to me that there's some overlapping functionality in what each map can do. Has anyone ever messed around with sketchfab as a way of adding textures? I tried it a few times but I found performance too slow on my machine. Going from the preview area, then saving, checking the results... I would probably do better with vray or one of these others

Say you had a surface with a hole in it and then shined a light on it. In addition to the sharp shadows cast by the rim of the hole, you would also see a more general darkening the deeper into the hole you got, because less ambient and bounced light would be reaching those points. That’s ambient occlusion. It’s a way to simulate depth by darkening certain areas. Enscape doesn’t use AO maps, but you can use them in a pinch if a texture pack doesn’t come with a roughness map. Inverting an AO map (so that the dark recesses are light and vice versa) is a decent enough fake of a roughness map, since smooth surfaces will reflect more and recesses will capture more light.
