Hi Dan,

Unfortunately Cubiquity for Unity3D does not currently work with Mac OSX as it relies on a Windows native-code .dll. We really need to make this clearer as you are not the first person to be caught out. We hope to support other platforms in the coming months, once the Windows version is a bit more polished.

Looks interesting, but can’t seems to make to run on OSX, do you have an installation/demo tutorial?

Awesome, thanks for that 😀 Great insight 🙂

Yes, it using separate texture units. This does put a limit on the maximum number of textures but practically speaking I don’t think it’s a problem. I also sent you an email with a couple more details for the blending.

I just watched the video, and that’s one hell of a material system you’ve got there! Excellent work! How on EARTH do you get smooth, soft blending between materials like that? Does it rely on newer graphics card features like texture arrays?

Oh wait, is it as simple as using 4 different texture units? Because it looks to me like you’ve got it limited to 4 materials per terrain. Still, it looks really great, so I think it’s worth it! 😀

Is the method ended up using for material blending a secret or can you tell me? Did you just end up splitting the meshes and blending along joins, as described in your Game Engine Gems article?

For smooth terrain it’s currently 128^3 and for cubic terrain it’s currently 256^3… but we are currently considering doing something different with the free version. The price of the full version is also a little unclear but I think we’ll launch at about $200 per seat and see how it sells. It’s really not fixed yet though.

Hey this voxel library looks pretty cool, thanks for sharing!

On the project it states that Cubiquity can be used for free with a limited size, would you mind sharing what this size is? Also for larger volumes how high is the fee?

Thanks Marek, I think that’s a nice idea. Actually I saw something similar once but I had forgotten about it: http://youtu.be/dEJtR_uy4zs?t=2m18s

I imagine it only works well for certain textures (rocks, etc) but I think we can make it toggleable per-material. Thanks for the tip 🙂

Hi David,

one suggestion: if you want to reduce repeated/tiled texture patterns on voxels, you can look on how we solved it in our voxel game (it’s open source)
https://github.com/KeenSoftwareHouse/Miner-Wars-2081

Basically, when calculating texture coordinates from XYZ, we just scale it to close distance or larger distance and then blend these two. Our pixel shaders are in that github archive.

Bye
Marek
