4.26 and Chaos are now supported. Chaos cooks collision 4.7x faster than PhysX!
Upgrade Notes
M_VoxelMaterial_Colors is not flat shaded anymore, enable Flat Normal on your voxel world if you want it to be
M_VoxelMaterial_Colors_NormalShading is gone, M_VoxelMaterial_Colors should be used instead
C++
VoxelWorldGenerator has been renamed to VoxelGenerator. All the relevant naming have been updated too (eg VoxelWorldGeneratorPicker -> VoxelGeneratorPicker).
Voxel Graph parameters
Voxel graph parameters have been refactored to be easier to use.
Instead of the Set Voxel Graph Parameter nodes:
You now need to use the Set Generator Parameter node. It takes a wildcard and works for all parameter types.
Voxel graph parameters are now always exposed: if you had a float constant node, it will be converted to a parameter.
Changes
Landscape Materials support
You can now use landscape materials directly on voxels! See Materials for a quick how-to.
Splines
Splines are a powerful way to add tunnels/caves. Both additive and subtractive splines are supported.
To add a spline to your scene, make sure you are using the FlatWorldGenerator and add Voxel Content/Blueprints/VoxelSpline. If you change its channel in its detail panel to Channel 1 it will be additive.
Generator properties can now be edited inline. This is a huge productivity boost! Works with both voxel graphs and C++ generators.
No Clipping Component
When the voxel world is loading, or when the player is adding voxels beneath its feet, it can sometimes clip through the world and fall to its death.
To prevent that, I've added a new No Clipping Component: just add it to your character, and whenever it's inside the world geometry (even if not loaded yet), it will be teleported to the nearest safe position.
You can place the component closer to the character feet for better results.
Flat Normal option
You can now do flat normals by using the Normal Config dropdown on the voxel world:
This will create additional vertices to ensure each triangle has a single normal.
I've also added MI_VoxelMaterial_Colors_WithShift to the examples materials: this material will shift the colors based on the normal.
Combined with the Flat Normal option, it can give some very interesting looks like this:
It now directly reads the palette from the .vox - no need to manually export them anymore!
It is now correctly converting the colors to sRGB/linear space as needed.
Tools improvements
Sphere Tool
The sphere tool can now paint with a falloff.
Smooth Tool
The smooth tool can now smooth paint data (only works with RGB data for now).
Custom Tools
Custom tools are now listed below the regular tools:
Custom tools are really powerful: for instance, the Graph Tool with the NoisyColors generator lets you paint noisy patterns like this (it's named Graph Tool, but works with both voxel graphs and C++ generators)
Behind the scenes it's just a color with some value shift by some white noise:
New Noises
These new noises are available as nodes in voxel graphs, and as functions of FVoxelFastNoise in C++.
Crater Noise
This noise adds craters. It looks really great when used as a fractal noise.
It's a relatively expensive fractal noise. An example is available in /Voxel Content/Examples/VoxelGraphs/Erosion/VG_Example_Erosion
The noise node takes derivatives (tick Compute Derivatives in the details of a supported noise node) and outputs an erosion value that you can then add to your original noise value.
There are purely a visual thing, similar to Break/Combine struct pins in Blueprints. You can combine any 3 consecutive pins that end with X/Y/Z and have the same prefix (so it works with a lot of nodes).
Height Splitter node
The new Height Splitter node is especially useful to do height based materials. Check /Voxel Content/Examples/VoxelGraphs/MultiIndex/VG_Example_MultiIndex for an example.
Batch compiling
You can now batch compile graph from the context menu:
New Examples
Craters
This map showcases how to use data items to add craters. This lets you handpick where you want the craters to be - however, it doesn't work too well if you have too many craters.
See the crater noise above for that instead.
Dunes
This one is a very simple graph generating dunes in a controllable direction
