The idea for this post came from a simple need. That is the need to have a high quality, low poly foliage model. Main reason for this is that if we go in an import raw assets the poly count goes way up. Coming from a 3ds Max background, when needing to create grass and foliage i would use Forest Pack Pro. The main difference is that in Max you are rendering still image so having many instances is not an issue. Well the answer on how to get that quality into Real Time is what drove the idea for this post.
Creating the Low Poly model
When creating a low poly model, or any model for that matter Reference is king. This means that you always want to have an image of what you are creating at hand. We will try to create a fern model like the one above.
Creating something like that means that we will need a texture to start from. In general you can either take the pictures on your own, and prepare the textures. Or you can go over on Google and search for a texture with an Alpha map. Or alternative route would be to go to a site that sells textures like that. In my case i chose a texture from Megascans as those textures are high quality 4k images. You will see me set up the textures, then individually cut out all the leaves. After this i will show you how to get a controlling points with the help of bend modifiers. And in the end we will even see how to add vertex color. The vertex color will later be used in UE4 for simulating wind. Knowing all this check out the video below to see how i did it.
Creating the UE4 Material
After creating the asset in 3ds Max we will jump over to UE4. Generally creating a material if you have all the nodes is a pretty easy procedure. You take all the nodes and plug them into the material and you’re done. You will see me create a system for the Vertex Color that will control the wind. Another thing that i will show you is how to increase the normal map strength. And we will also see how to control the diffuse strength with the help of scalar parameters. Even though it’s not that complex, some of the tricks there are pretty cool so check them out.
Creating this post i have to admit was fun for me. Main reason is that i did a bit of research as well so i picked up some skills. I would like to say one thing to everyone out there, don’t be scared of trying new stuff. I have received multiple messages of people telling me that UE4 looks too complex. Well honestly, it’s really not that complex as long as you approach it with an open mind. Another driving force should be the fact that UE4 is going to be the main tool for Archviz. Maybe this will take some time but it will get there. So with this post i showed you the basics of creating foliage so you can use it in your scenes. I’ll see that in the future i make more videos about modeling, and then using those models inside UE4.
Until then though, everyone stay safe and keep on learning.
Here we are for what is probably the last post of the year. This post actually came up as a sort of a way of me making it easy on myself. I had to explain how to help get smooth rounded edges without adding extra geometry. And on top of that there needed to be some randomness to the edges roughness. With this in mind i decided to create this tutorial that might help some of you ou there as well.
For the video i actually decided to go with a simple model of a table and bench. I’ll go over the difference of using chamfered edges over sharp edges. After that we will see how to get the illusion of rounded edges without actually adding in extra geometry. We will see how using a VRay Edges Texture can be used in the diffuse and the bump slot. And later in the video we will also see how to take this one step further and add variation. All in all it was a simple, yet fun video to make so i hope you guys enjoy it.
After watching this video you probably have an idea of how to use this in your future projects. And with this we end today’s post and this year’s last video as the date this got posted is 31 of December. So as i am finishing up this post i would like to wish everyone a Happy New year and may the next year bring you happiness and prosperity.
Well in short this post came to be as a direct request from one of the subscribers. Namely i was asked how to create a realistic car paint material. Initially i thought it would be a short and boring topic to cover it for a video. Needless to say i was wrong, so very wrong.
Starting at the base
As soon as i started taking a better look into the car paint shader it started to get interesting. To get a realistic car paint shader you would need to approach this as it was in real life. If you have ever bothered to read about car paint, you will learn that it’s a multple layer color.
In the image above you have a case where the paint of the car is getting damaged. This actually allows us to see that even though this is a metallic shader, the base is actually very glossy. This means that the first layer will control the color and doesn’t need reflection. As soon as we get that done we can go over and create an additional layer for the coating. Once we have both of the layers created we can call it done or we can push on.
The next step was to create the flakes you see in the metallic color when it’s sunny outside. To get this result i used Vray stochastic flakes material. This is a new addition to Vray since 3,6 . That means that if you want to get the same result as me you would need to have that version. So if you want to see how i did the basic shader for the car paint material check out the video below.
Creating the Pearlescent color shader
After creating the basic shader i thought about pushing it a bit more and create a pearlescent version. That is basically a paint that changes color depending on the angle of viewing. You can see how that looks check out the image here.
As you can see it looks cool and it’s really not that hard to achieve. What i did was mix a different diffuse color base with a different mix curve and got the result. But since rarely are things in Max that simple you can see me doing it in the video below.
So if you followed the two videos you now know how to create a basic and a pearlescent shader. And with that we put a end to today’s topic. As always if you enjoyed it make sure you like the videos, comment and share. And don’t forget to come back for more next time.
