hey what's up guys Nuno here! Today it's a special video
it's a request that many of you asked and it's actually quite simple to do how
to add megascans vegetation in lumion i'll show you step by step two ways to
make this and i'll show you how to avoid a common mistake people make when
importing these vegetation assets into lumion
but before we start if you like to learn more about how to get those realistic
renders have a free training for that that you
can sign up for i'll leave a link in the top right corner and in the description
below this video
so as i said in the beginning of this video this is a pretty simple thing to
do and you can just go here to the quixote
bridge you can download this quixo bridge
at the quicksole website and once you install you'll see it like this
and you can go here to collections and here you have vegetation so they have
these collections aquatic craters grass ground cover
tropical for the purpose of this video we're going to select this tropical one
now let's see what we have here maybe this one this one
so i'm gonna select this one here you can click here to maximize
okay so you can see better how it looks you can see the textures
and also how the model looks the geometry
so it's with this here because this is the geometry
it will have an opacity mask so let me go back here
and i can close this up now if you go here to this gear icon
you have download settings for lumion what i
add is the albedo okay i always select the jpeg
we have the gloss the normal actually this one
away and displacement and then for models i have the load 0 so it's the
model with the highest resolution and i also have here eyeballing source
if they have a high poly source i like to have this as an option but
for this case i don't think they have so let's just
leave this on and of course as fbx and let's go back and now we can just
press here this button download so now let me show you here i have so
this is the folder with the preview
okay that just downloaded and you have several variations each variation comes
with a different lod so different uh resolution of the
model itself of course the load 0 will be the most
costly in terms of performance but for this type of models it will be
running quite fast we have no problems so you have four
different variations for this plant and you have the textures here as well
so the textures as you know we have to load them
into photoshop and here in photoshop as i've been telling you for a long time
already you need to invert the the green in the
normal map and actually many people ask me about
this and if you don't invert the green on
this channel you'll have some issues with the lighting
this particular model will be within correct lighting
so always do this in the textures that come from
mega scans and from polygon and then the gloss map
i'm just going to press ctrl a ctrl c i'm going to create on the channels
here on the channels you will click here on the bottom
and create new channel okay now we have this empty channel i'm going to paste
the texture okay that's it for this i can just press
save and i will save this as targa
and white target because targa has the 32-bit channel
and it's just with a 32-bit channel that we can have this uh
out gloss map as alpha channel so let's do this
and we have here 32 bit channel okay if probably by default it will be like this
for the 24 you just press here 32
okay now let's go to lumion
and i'm going to save this i'm going to go here so now let's go
here to import and i'm going to select the folder and
so i'm gonna select this one load zero let's open
and i think we can name this cat palm so let's
cut palm plot zero okay
all right replace it
okay here it's fine okay you can see the model
and now let's slow the textures let's select the
material standard and go here choose color map
and now go here to textures atlas and select the albedo so this albeit
with the color map in lumion
and it's all dark and weird and actually you can still see all the
geometry why so the first thing the dark is very easy
to fix just go here to the colorization and
reduce all the way okay now this one we need to take the
texture to photoshop and apply the opacity mask in the alpha
channel as well of the albedo so let's do that
and if you notice i don't have here any opacity mask
and why because i forgot to tick here on the
export settings here download settings the opacity mask so don't forget you
also need the opacity mask for this vegetation assets okay so now we can go
back and download this again so i already
have here my albedo now i'm just going to go here to again
to channels create alpha go here to the opacity mask
ctrl c to copy it and paste and now i'm just going to save it
and save okay
now let's head over to lumion and select again the color map
and now let's load the target file which one the one that has the alpha channel
okay now we can see that it's transparent this area
and we just see the the leaves itself okay so
now let's remove first this normal okay because it was the normal map that lumin
created automatically but we don't need that because we have
our normal map and we're going to actually
and we're going to select it and open
okay so you can already see more or less how it looks
okay so what i usually do here it's i adjust just a little bit the
the reflection so if i want a little bit more or less
and also the weathering i leave it in the stone and increase a little bit if i
want more a little bit more contrast here in
these areas on the shadows and lastly it also depends on the type
of plant but if it's a plant that when the
sun for example like this it's hitting from
the the back it will have more of this subsurface uh
which means that it's the light passing through the leaves so
if i want that i can just adjust here this waxiness okay
so you can see a little bit of difference here but for now i'm going to
leave it off and
let me just go to the render
move this more to this position
so you can see that this is looking great but i said that i wanted to show
you a common uh mistake that people usually
do with this type of assets and it's this if you look
from the back the lift disappeared okay here you can see here there's
nothing okay nothing nothing nothing and from
the top you can see and why is this happening because you
just have on one face don't have double sided the material and
so you just it's just drawing on one side okay so
this side no and this side is drawing so how can we fix this there is actually
one very easy way to do all of these types of assets
and we're going to do this with lime exporter
so let's get back here to quick saw bridge
and if you open 3ds max and now you go back to bridge with the
same asset i'm just going to click here to export and now this is going to
open this asset in 3ds max
okay here i have the asset i think it's with a lot of
a lot of these different versions together so let me just separate a
little bit this okay i'm gonna delete this one this one
is fine actually i'm gonna move this one here
and okay something like this
so for this i'm going to use the lime exporter version 2.
it's the one that works best with this type of assets
and so here what we can do to fix this issue we can select the
models one two three and we can just click here
correct model okay now you'll see this a little bit of
this triangulation here but it's it's okay this uh the model
will be fixed now you can even click here uh show model
error i actually have to select show model
error and then correct the model okay let me
go back to perspective you can click simply
click here show textures okay like this actually
here okay this should be the top view okay
and now with this i'm going to click click here whole scene
so it's asking me to save the scene before because this scene wasn't saved
anywhere it just exported directly from from
quick so bridge so let's save it i'm gonna call this
bobcat
okay now i can export the scene
so once it's done i'm going to ask you to download the file so i'm going to
click yes and it will go to your browser and so
this is the file i'm just going to place it on my folder
okay now here in lumion let's load again this
so okay now we have here the new one from lime
okay and let's see so as you can see now from all the sides you have leaves
okay it's not happening like this one and this one
already disappeared and this one here is still there see
okay so it's clearly one of the benefits of using lime
because it does all of this automatically
and now let's go here to the material and
standard and here it's already as well with the
opacity as you can see so i don't have to do this again and
with the normal map i'm just going to load that
normal map that i created before
okay just going to adjust the parameters again
a little bit actually on this one i'm going to increase the waxiness all the
way just so you can see the difference let's
go to the render
okay
actually let me just move it more to this side
okay actually let me just adjust a little bit of lighting
here
and i'm also going to remove now the
waxiness so you can see here all of these
elements
so and you can do this with a lot of different assets
i have here already a couple of mega scans library
so even this a lot of this ferns
so you can place all of this and start creating your
environment
so
and so you see that one thing that you need to pay attention is that
these assets are made for video games so they don't have a lot of geometry even
though they are quite detailed they are not as detailed as you find
from sites like max tree for example or even in polygon you have some
very very nice plants so this these elements are nice for example
especially since they are light as i said to use in video games
to use at more elements like this on the on the background at a little bit more
distance so because it will not have such an
impact on your performance as the others they also look quite nice as you can see
here all of these elements
and by the way if you want to learn a little bit more about mega scans and
what is mega scans i also have a video for that and i'll leave a link in the
top right corner and that's all for today let me know if
you have any questions the best place to ask me it's in the comments below this
video i hope you like this video and i'll see
you in the next one
