Hey Justin, what you were doing was actually copying a NORMAL map into a Displacement map. And in all honesty, you're not supposed to do that. Displacement maps are only black and white which is meant to tell the software to either go up or down (often compared to a height map). Think of the mortar between the bricks. While Bump map and Normal maps are quite similar but they're meant for details, like the small bumps on the brick. So when you copied the Normal maps to the displacement, you were telling the Mortar AND the small grain details of the brick to be pushed and pulled. Not to mention the Displacement map is not supposed to read the RGB Normal map, you can fake it with a bump map but it's still not recommended. That's why the render of the bricks looks really odd up close. In practice, we do use displacement maps a lot, especially in combination with the Normal or Bump map. There's a great article explaining these 3 maps on Plural Sight ^.^
Thanks Minh - I really appreciate your knowledge in this area. I think I found the article you were talking about here - www.pluralsight.com/blog/film-games/bump-normal-and-displacement-maps . I am curious though when you say that it's not recommended to use the bump map for your displacement - if you don't have a texture with a full-on displacement map, what's the downside of using a greyscale bump map for the displacement? Is it just that the details (like you mentioned before) get pushed and pulled? Thanks again!
The Rendering Essentials yeah so it depends on the bump map. There are usually two scenarios, one is that the bump map is meant to add the small detail And the big detail, in that case, there's no need to use a displacement map. This is what most of the built-in vray material uses. As for the other scenario, the bump map is used in combination with the displacement map. In this case, the bump map won't add the "big detail" like the mortar lines, or spaces between wood planks. It will only add small details while displacement add the big details. So when you're copying the bump map in place of the displacement map, for the first scenario, there needs to be a lot of adjusting to make it work correctly, but for the second scenario, it would be hard since that bump map doesnt have the big details. VizPeople has a collection of free wood floor maps, you can download and see the difference between bump and displacement maps.
Thank you so much..... Currently I am a student at university in Vietnam. And I had difficult about finance, so I did not learn Vray in lerning center. But through your videos I can learn many thing about vray and construction. And right now, I really feel happy because I learned many thing about you. Once again, I just want to say thank you very much......
Hello Justin, it went well with Bump part, but not able to apply displacement on single color, since I'm using SketchUp Vray 5 which has a different asset editor. Would be great if you ever have time to upgrade tuto to V5. Thanks for your great teaching.
Great tutorials as usual 👍,really thanks I started an interior model and I added some spotlight from Vray spotlight tool , but when I go for rendering, the spot light is not appearing in the seen ( other light features appeared very well), I changed the intensity to different values , also I changed the camera exposure value many times, but it seems like the light is not there at all, advise me please.
Hi, I am following the steps and have used a bitmap displ. in graytones simulating pebbles. The preview in the vray material properties looks like it should and changes based on ammount and all that, but when rendering the scene there is no change in the material in question. Even when trying only a simple face, it renders it as nothing was applied. Any help? ::)
Hey man appreciate your work! It would be great to see a video on how the displacement has changed since Vray NEXT. I am struggling to get displacement to work. Am i right in thinking that the method has changed since then?
is it possible to use multiple bump maps on a single material? I'm trying to use the VrayEdges material (so I dont need to use the round edges plugin) but I still want to have the roughness from a bump map. I'm not quite sure how to use them at the same time
I applied the maps correctly,they are even visible in the materials preview window but for some reason the bump doesn't appear in rendering buffer window,can you please give a solution to this
Thank you Justin for the great tutorials.I'm new to SketshUp and you ARE my teacher. I wonder if we can use this method, to apply the generated texture (by displacement map) to the actual model geometry in SketchUp (not just In V-Ray renders), so we can get a (textured 3D print of it?) or if there is any other way to do that, I hope you make a tutorial dedicated to that! Thank you again.
I'm not aware of a way to do this - you might be able to load the displacement map into Bitmap to Mesh - ua-cam.com/video/s6EM1MQTlrw/v-deo.html - never tried it though
Hey, I m really interested to know your laptop or PC configuration and also want to know what will be the sufficient configuration for the laptop which can help to work remote place. Really need your suggestion.
I'm curious to know where you store your materials on your hard drive. I often create my own materials in Photoshop and never know where to keep them where Vray can easily find what I've imported into my SU scene. Thanks so much.
At the moment I store them in a folder on an external hard drive, but I also haven't done a whole lot that's required me to create a true Vray library of files. If you work with tons and tons of materials, I'd think you'd want to store them in whatever way makes the most sense for your workflow...
Thank You so much, very nice video. BTW, why the many standard maps have such blue/purple color? And not only standard. So many external textures use the same color. What's the point? )
The Rendering Essentials I think I can certainly justify it. I did a decent render of this room I made years ago. It is excellent and fast. Twilight Render is good but doesn’t offer GPU rendering. I got a 2013 Mac Pro with dual GPUs. Set the render time to 2 hours and it did a smashing job in those 2 hours. The same room might’ve taken a week in Twilight at even a medium quality. I tried Vray a few years ago but the demo didn’t install right or something didn’t work properly for some reason. This time it installed flawlessly.

I might not use this often, but am happy to know about it.
Thanks.
Thanks very much! It's always good to know about your options just in case you need them :)
is it possible in new vray to do that the edge of geometry is not change by displacement? i want it on plane but not in the edges of model:(
thnK u JUSTIN ur tutorials are very much helpful....!!

if u need to change the scale of te materil is he bumpmap follows it?
Nice tutorial, as always, dude.
Thanks very much! :)
@@TheRenderingEssentialsI didn't get to say it but the most enlightening element of the tutorial was from 6:50 onwards i.e. V_Ray UV Tools.

Depends on what program you're using - www.therenderingessentials.com/mypc

hey can you link in the tutorial for rounding edges , like you mentioned in video , Thank you
Thank You so much, very nice video. BTW, why the many standard maps have such blue/purple color? And not only standard. So many external textures use the same color. What's the point? )
Those are normal maps - they store the coordinate information in an RGB format, which makes them more accurate
Sold! Now I gotta get Vray. Twilight Render is nice but Vray does so much more and it does GPU rendering.
It definitely does have more features - if you can justify the cost... :)

thanx for this video
very helpful
great video sketchup wizard
I don't have bump and displacement maps, how can i make them?
Hello Justin, I know you are busy but I really need your help to fix something in unreal engine project exam. Thank you
How do you change the scale of the bump or displacement map?
I found the option under Texture placement in the Repeat U/V values.
If you make any video of V-ray in which you explain about UV Repeat and UV offset please paste the link here.
good for close up :) thanks !!
Thanks very much - glad you found it helpful!
in my system, bump and displacement are not working, please give me suggestion ---- Please reply
"It's not working" doesn't really give me enough info...
where can i download those for bitmap? need it badly.. please
They usually come with the materials when you download them if they're PBR materials...
You can copy maps easier by RIGHT clicking the litlle box from 12:10, then press copy. Right click another box and press paste.
Cool - great tip!
Good job! Thanks a lot!
Thanks very much!
Thank You Sir.......
yeappp you are true, bumppppp mapppping is usefull
:)
why do you always reverse the faces?
What about a "Rough" map? Texture Heaven has Bump, Displacement, AND Rough...
i can't find maps window in v ray next .. sk2019
same here
@@carrie4944 i found it hahah
@@samisaeed9287 where is it. Lol. I m using vary 4.2
Do fabric texture for realistic rendering
Thanks for the suggestion - will add to the list!
