- In today’s video, I wanted to talk about how to add grass to your renderings in Vray for SketchUp using Vray’s fur creation function!

In this case, I’ve created a bit of rolling terrain using sandbox tools within SketchUp, and it’s in there as a grouped face.
To designate this as a Vray grass object, go up into the Vray Objects toolbar and select the option for “Add Fur to Selection.”
This will designate your selected object as a grass object - notice that you get little icons around your group indicating the fur object.
Now, if you run an interactive render and zoom in, you’ll notice that Vray is adding fur to your object within your render, even though the geometry doesn’t physically exist within SketchUp.
Now, let’s make a couple changes. The first thing to change is that we want to add some color to your grass. To make changes to Vray objects, we need to go into the asset editor, then go down to the material dropdown. From there, you can apply a material to your grass. I believe that for a color to show up in your dropdown, it may need to be in your model, so you can just create a quick face and apply the color you want for your grass, then it will show up in the dropdown.
One thing you’ll notice is that the grass doesn’t have a background color. We can change this by applying a color to the outside of our grass group. In this case, I’m actually going to apply one of SketchUp’s grass materials rather than a solid color to break up the surface a bit more.
Now, let’s take a look at some of the actual grass settings in our model. The first section allows you to adjust the amount of grass being applied to your face - larger values add more grass, smaller values less.
Length, thickness, taper, gravity, and bend all adjust the way your grass looks. For example, if you want longer grass, you can adjust the length slider.
Thickness adjusts how thick the actual grass blades are.
Taper will adjust if your grass goes from thick at the base to thin at the tip.
Gravity and bend will change how much your blades bend over.
Global scale adjusts the overall size of each piece of grass.
Curl will add curl to the fur.
Level of distance will adjust the amount of grass that’s shown as the camera gets further away from the camera. This can make your renders faster as Vray doesn’t have to calculate all the

Thank you so much !!! your video is so useful i was trying to make my carpet it was not happening as i want but after watching your vid i got that ✨
Thank you once again for your epic tutorials. Dont know where i would be without these.
Really glad they're helping - thanks!
Thank you very much!!! Really very useful!
Greeat Video man, helpfull!
Justin! One again, you're the man.
Thank you! :)
Hi Justin !
Thank you for the video.
I should play more with " grass " in V-Ray.
Not just grass - it can also be used to add fur to objects! There's some fun ways to use this one. Thanks George!
Nice grass intro Justin.
Thanks very much!
Thank you!
Used your info to make my grass in Rhino 3D. Thanks so much!
Glad I could help!
Does this fur option animate when you create an animation? If not which I am assuming, how do you make it so that the fur animates to natural wind properties when rendering an animation?
I'm assuming you'd have to incorporate some other animation program - possible Unreal Engine or Unity? SketchUp does not have this level of animation functionality that I'm aware of. Thanks!
Thanks a lot Justin! best tutorials in youtube man!
Glad you think so!
thank you
Fur not showing up. Reverse faces, nothing changes. Any idea?
Thank you so much
Thanks for watching!
Hi, thank you for great tutorial. Btw: how to avoid grass growing through an object?
Very helpful and concise video
I'm finding it difficult to get that Vray fur!
WHUUUUUUUUUUUUUUUUWHATS UP GUYS!!!!!
and how do you deal with the fur appearing on the wrong side of the geometry ?
It’s happening with me too
how do you flip it?
Great help, Thanks
Thanks for watching!
I have follow your guides but the grass didnt change the colour..it stays white..why
Hi, thanks for the video! Grass in the texture is light green and grass in the render turns out to be a much darker green. Is there a way to keep the brightness of the texture in the render?
I have same question
Were you applying a colour separately to the grass, like Justin shows? What works well for me is to apply a grass texture to the face and let the Vray grass take the colour from the texture. If I apply a grass texture with mixed colours, then the vray grass uses the colour from the texture, so I end up with a nice mix of shades of colour and looks more natural.
Thank you!!!
very helpful,THANKS...$$$
Hey Justin great vid as always...just a quick one if you can...for objects placed in grass/fur how do you get them to displace the grass/fur around them? I have a scene with recliner components in the grass and it's popping up through the chair itself. Is there a solution to this? Thanks in advance.
Honestly I'm not sure on this one...
Pls I need your help guys, the fur keeps growing in the opposite direction on plane surfaces and contours like instead of it to grow up it grows downward
had the same problem a few minutes ago... just right click the group you want to add the fur on and go to flip along then select Groups Blue axis..it should reverse the surface..it's not official way of fixing but it worked for me..Good luck :)
@@ralpheccentric5717 yh so I actually figured it out u are making your grass on a back face that's why u need to make sure it's properly oriented then make group then add fur
@@luiskwegan1088 thanks..i realised and just reversed the face along the blue axis
Pls do more videos on fur @Justin
What specifically would you like to know?
Vray fur functions in interior design!! Thanks @Justin
Do you have any idea why do the grass appear on my opposite surface? I know i can flip the blue, but since my model is not a flat surface, it’s a little bit burden me. Thank you in advance!
If you flip it, does it fix it?
I don't know why but vray 3.4 and up is seemed to be very hard for me. For that I am using vray 2.25 on sketchup 2016. For modeling I am using 2019.
How to avoid fur to that tile or certain area?
I have a different option in the asset editor. The is no material option
What version of Vray do you have? If you have a version other than 3.6, it's probably going to look different...
Why I don't have the fur
No clue
fur comes bottom of plane why
Did you try reversing your face so the other side faces up?
Hi! I'm following all your steps and the color is not applying to the grass... Do you know why?
Did you apply the color directly to the geometry inside the group, or to the outside of the group?
What's up guys? Justin here with Theee Rendering Essentials dot com.
Hello! How many RAM do you have?
Thank you. I've learned so much this quarantine because of your videos!

Why is it so hard to add fur?!?!? Sometimes it works for me and sometimes it doesn't. I reverse the faces, I make a group AAAAGGGHHH!
