What’s happening ladies and gentlemen,
this is Minh from Architecture Inspirations.
Today I’m going to show you how to create Fire
in Vray 3.6 for Sketchup. Let’s get started.
So here I have a model of a Cabin in the Forest
that I’ve been working on for my members on Patreon.
I wanted to create a night scene
with a fire pit on the exterior
that light up the model like this.
So In this video,
I’m going to show you how I created that effect.
Here is the fire pit that I used in the model,
as you can see, it render quite nicely.
Now I’m going to change the time of day here
to switch it to a night time
I’m going to create a box around my fire pit like this,
and delete one of the faces so I can look through it.
This box is to let me see how
the fire affect the surrounding environment later.
Now we need to add a light.
I’m going to use this Omni Light here
and add it right on top of these firewood.
Then I can open up the asset editor,
go to the Lights tab, and increase the intensity here.
But first, I will change the decay to Inverse.
And now I can increase the intensity to 3000
and change the shadow radius to 100
so the shadows will be softer.
Next, I’m going to click here, and enter these values,
to the light will be more of an orange color.
Now we need to find some images of flames.
I just use textures.com,
go to the FX section, Fire, Flames.
Here you have a lot to choose from.
Just download a couple of them like I did here.
Next, we need to turn these into PNGs
with transparent background.
So I will open one up in Photoshop.
Now I can alt and left click
then drag the image up like so to make a copy.
Then I will press Ctrl+Shift+U to desaturate the image
Now I will press Ctrl+L to bring up the levels,
and adjust these sliders like so.
Next I press Ctrl+A to select all,
and Ctrl+C to copy this image,
and turn this layer off.
Go to the original image,
and click here to add a layer mask.
Then Alt and left click the layer mask to isolate it.
Then press Ctrl+V to paste the new image here.
Now click on the original image.
There we go, it looks transparent now.
Now I can go up here and Export it as a PNG.
Let’s go back to Sketchup
Go to File - Import
and we’re going to import the PNG as an Image
Next we need to rotate it like so,
then right click, explode it.
Then we need to make this a component.
I’m going to click here then set the axes
at the bottom center of the flame like this
Then I’m going to check this “always face camera” box
And click create.
There we go,
you can see that wherever the camera move,
the image is always facing it.
This is called a face me component.
Now I’m going to place it on top of the fire pit.
Then bring it down a little
There we go, looks good
Let’s do a test render.
As you can see, the flames look really dark.
So let’s open the asset editor, and find that texture.
I will name it as Flame 1 to make it easy to remember.
Then go to the Quick Settings tab,
and change the type to Emissive
Next, move the Transparency slider
all the way to the right,
we also need to uncheck this “color opacity” box here.
There we go!
Now I can change the intensity here to make it brighter.
30 is too bright, so I will change it to 2.
Looks good!
Now let’s move the camera over here.
As you can see, the flames look really flat,
but if we stop the render and start it again,
then it looks correct!
Pretty cool huh?
Now just use this workflow
to add more flames textures.
Just use Photoshop and turn them into PNGs
Then Import them into the model.
Rotate them.
Turn them into face me components.
Then place them in the fire pit.
You don’t have to line it up perfectly with the first texture.
You can offset the three textures like this.
Now I can use the previous workflow
to edit these new materials like so.
After that, run the interactive render.
And now you can change how the fire looks
by positioning the individual flames textures like so.
Now if I go to a different point of view,
and re render it, you can see
that the look of the fire is completely different.
As you can see, having 3 different flames textures
just make the fire a lot more dynamic.
Once I’m happy with this, I can now group them
and bring this into my main Sketchup model.
There we go, that’s how you can create fire
in Vray 3.6 for Sketchup
If you want to get this model,
sign up on Patreon before the end of this month,
which is May 31st, to get all the files for 5 dollars.
Otherwise, you can get it on Gumroad
but it will be for $15 dollars instead.
And that’s all for today guys!
