@Tristan: I studied computergrafics for 5 years. I'm making 3D art now since about half a year fulltime, but I had some experience before that. Its hard to focus on one thing, it took me half a year to understand most of the vegetation creation pipelines. For speeding up your workflow maybe spend a bit time with the megascans library. Making 3D vegetation starts from going outside for photoscanns to profiling your assets. Start with one thing and master this. @Maxime: The difference between my technique and Z-passing on distant objects is quiet the same. (- the higher vertex count) I would start using this at about 10-15m+. In this inner radius you are using (mostly high) cascaded shadows, the less the shader complexety in this areas, the less the shader instructions. When I started this project, the polycount was a bit to high. Now I found the best balance between a "lowpoly" mesh and the less possible overdraw. The conclusion of this technique is easily using a slightly higher vertex count on the mesh for reducing the quad overdraw and shader complexity. In matters visual quality a "high poly" plant will allways look better than a blade of grass on a plane.

Is this not like gear VR or anything else

Thank you!

Brushify - Multi-Biome Landscape Shader

We’ve recently shared an interview with Joe Garth about Brushify, the artist’s terrain library with 8k res meshes and terrain Alpha brushes that lets artist build high-quality landscapes directly in UE4. The artist continues to develop his toolkit with the biggest update being the Multi-Biome Landscape Shader. We’ve decided to ask him a couple of question about this cool new tool. 

What’s new with Brushify? is a Modular Environment infrastructure for Unreal Engine 4. Multiple Brushify environment packs are available for purchase on the Unreal Engine Marketplace.

In the last month, Brushify has gone through some big changes, with new packs and new features across all the products.

The biggest update is the Multi-Biome Landscape Shader. This advanced material allows all the Brushify biomes to be blended together seamlessly. For example, you can blend desert, beach, grasslands, snow all in a single scene.

Here’s a 10-minute tutorial showing what’s possible with the shader:

Why is a landscape material like this important?

For open world games and MMO’s, it can be really difficult to build massive worlds. Especially when the terrain materials available are so limiting. Sometimes terrains may look good, but they aren’t modular and can’t be edited. Other times dynamic solutions like auto materials can be very performance intensive. Brushify aims to both look good and run well even on low spec systems.

It’s also usually not possible to blend multiple auto materials together. So you may have a perfect desert biome in your game, but have no way to blend it into the grasslands area that’s a few kilometers away.

What about performance?

The landscape material is optimized for Consoles and VR scenes. With close attention paid to overdraw and draw calls for the assets.

The more landscape layers in an area, the more the overdraw will increase. But thanks to the fact that each Brushify layer already handles, 3 levels of detail, automatic slope texturing and cover texture for snow or dirt, there isn’t as much need to paint down a lot of layers by hand. You can still easily combine 5-6 biomes in one location without a huge performance hit.  

What’s the future of Brushify?

My plan is to expand Brushify into as many biomes as possible and eventually into large kitbashing kits for various game genres. I’m also working hard to include modular photogrammetry assets in future packs.

Interview conducted by Kirill Tokarev

“Brushify is a next-generation terrain library. It contains high-resolution terrain created from real-world data. Terrain packs are available as modular environment packs for Unreal Engine 4 and source assets are available on Gumroad and Sketchfab. They come with unique 3D mountains that can be used to build 3D landscapes and game levels quickly and effectively.”
