hey what's up guys Nuno here in today's video i want to show you some simple
things you can do in photoshop to increase the realism of your 3d
renders so this will be some small details that will head to the render
and these small details will add a little bit of more immunization to your render it just takes
about five to ten minutes to add all of this and it really increases the realism of your render
but before we start i want to let you know that i have a free training called my top 10 secrets to
achieve realistic 3d renders i'll leave a link in the top right corner and in the description
below this video so without further ado let's get started so in this video i'll show you how you can
increase the realism of your render just by adding some small details in photoshop so first head over
to this site it's called textures.com and here as i told you before you can create a free account
with this free account you have 15 credits that you can use daily so here i'm just going to type
decals and it will show up a lot of these details that you can use it can download but on the left
side you also have here decals and i prefer to use this on the left side because here you have
categorized by bottom damage leaking rust spots etc so let's go here to the bottom now here you
can see that a lot of these already come without the background which is great so we can use it
immediately in photoshop without having any extra work and if i click on this one you can see that
they have a lot of different resolutions and the free ones are usually the small ones but
for what we're going to do the small ones works perfectly we don't need more than that
and so i already downloaded a couple of these from the bottom from leaking as well it's very
important these ones and i'm going to show you how you can increase the release when your renders now
in photoshop with these textures so here i have my render and the first thing i'm going to do is to
go here and just drag and drop from your folder the texture it will show up like this just press
enter and now i'm going to actually press ctrl t again to move it press
enter i'm going to place this one this is a bottom one i'll place it about here actually going to
increase just a little bit more and to fix the perspective we can click right click and go here
and distort and now just move this one slightly up about here try to line up this more or less
okay like this is fine but now this part is on top of the bike and on top of this box as well
so i have here my color map this is why it's important to let me show you this first to have
the color map when you are rendering so you have to select this one because like this it helps you
to do some small adjustments in photoshop easily so let me go back here and now i can just go here
i'll select this bike and this box as well now i'm just going to click this eye icon to the select
and i'm going to go select this one and i have to go here to select this marching ants again and i'm
just going to right click and select inverse now with this texture selected i can simply go here
and add layer mask click ok so now we don't have on top of the bike neither on the box
now we're going to select this and put multiply and so for this one you see that it adds a little
bit more of this mouse here you can go here to the fill and try to reduce a little bit to
match a little bit to the background but actually for this one i like it at 100 okay let's go back
for example this part if you have a tree next to the building for a long time maybe to start
to have some dirt here so i got some from this leakage area and i'm gonna place it here
about here and again i'm just going to the mask and i'm going to mask out this part
so i'm just going to select inverse and make the mask the same way we did before okay and now i'm
going to put this as multiply and with this mask selected now i'm going to the brush tool
here and with a large brush with a softness at actually the hardness at zero percent
i'm going to start to erase some of these areas
you can use your numpad to type in 100 10 10 20 and it will start showing here changing here
the the opacity like 35 50. so i'm always using this so 100 to first remove a lot then i put it
at about twenty percent and head back a little bit and now you can uh press x on the keyboard
to swipe between black and white and so the the the white will add and the black will erase so
so let's just on some parts so it's a little bit more
uneven the color so not everything is completely dark
and another thing i'm going to do i'm going to go here and add uac iteration
and press alt oops press alt let's zoom back
so it just affects this mask this layer here
and i'm going to increase the lightness and this saturation so i see what i'm doing
and actually i have to press colorize now lightness and saturation
okay now you see that it's giving some color so i'm going to give it like a brownish color
and a little darker okay so before and after
so if you feel that this is still a little bit too much you can go here and on this field just reduce
a little bit but here i think it's fine let's see it without and with okay that's looking good
now let's go here to add one more let's go to the liquid licking and add this one and this one
is all red why because i place it on bottom of this part so i need to move it up and now i can
just alt and make this to the bottom again so now it's fixed now let's add on this area here
and try to match the best that line there and go to distort move it up
if you hold shift it will just move this vertically so try to maintain the the perspective
for this one i'll put it at multiply and already is already the fill just a little bit
i'm about here it's fine i'll add again the mask and i'll erase some of it
so it's not on every part of the building
and i'm going to duplicate the same one and i'm going to place it about two
out here
now i'm going to erase this part so it's less visible there and a little bit here as well
okay let's see before and after before and after so you see that starts to add a little bit of this
details to the building and gives an idea that it's already a little bit where so actually we can
add one here just slightly like so well actually
it should be like this and now with the distort we move this down holding shift
okay and now just multiply and on this one i want just very slightly effect and just in some areas
okay actually you see that this is too much on this area so i'm going to reduce a little bit more
okay now another thing if you have usually a tree for a couple of years right next to
the building it will start to create some dirt right so on this area i'm going to add this one
and about to here let's line up and now let's go to the distort again shift and shift
and just hold like this okay so it's a little bit distorted but it doesn't matter because
it's just to give some color here some dirt on this area so multiply and let's just first
erase this bottom part here okay now erase a little bit here because it's too too dark
make it a little bit more even more random
okay i think this looks good all of this has to be
settled if you put this effect really really strong i think it will kind of
break the the idea of this which is just to give an extra detail on top of the render
another thing we can do we can go back to the website and here let's search for graffiti
so you can see you have a lot of graffitis here
that you can select and i already downloaded a couple of these and now load here this one
okay now we need to go here right click and rasterize and now we need to press ctrl
i so it inverts and now let's make it multiply and press ctrl l so it loads up the levels
and let's push it until we don't see that frame okay press ctrl u for the saturation because if
i increase you see that's too red so let's just decrease a little bit about 40 percent is fine
and now let's move this down to about
here and let's reduce the feel just a little bit
and lastly another thing i want to show you it's this area here even though it's the same
glass as this one and as this one it didn't cut any reflections so one simple thing we can do you
can just go here and with this mask select this window and now select this render and press ctrl c
ctrl v now we can move this actually first let's delete this part and let's
increase a little bit this place it like this and now let's go back here and select this glass
and now here with this marching ends you press the mask okay and let's change it to screen
and now we can change the opacity lower a little bit about here it's fine and so without and width
so just a slight change but it really gives this glass look that you didn't add anything before
and now you can see that it's a glass and so now if i select all of this and place it in a group
if i hide this you see that all of this starts to add a little bit more to the render right and this
is just some small things that you can add and of course don't forget that to have this realism you
have to have as well these proper textures and if you want to know how to create these realistic br
materials i also have a video for that i'll leave a link in the top right corner and in
the description below this video and so this thing takes what about five to ten minutes to add them
and they really add a little bit of extra detail to your render and that's it for today i hope you
