@radulphi Hey, I'm a 3D modelling student looking to get into voxel modelling, but I can't seem to find any free voxel modelling programs. Can you suggest any?

[radulphi]

@Ringwaul I'm sorry, I don't know of any that are free =( - you're probably already aware of 3D Coat. Should you decide to buy it, the youtube channels PILGWAY3DCoat and philnolan3d offer great resources for learning.

[radulphi]

Thank you all for your interest, feedback and kind words.

how would shadowing work with voxels? If an object is loaded at whatever resolution of voxels but its shadow is being cast into an area that demands a higher resolution (i.e. closer to the camera), would the shadow appear blocky?

[radulphi]

@MakAttak101 Both shadow mapping and stenciled shadow volumes compute shadows in a pass separate from the final rendering pass. Therefore, you can choose a different (appropriate) level of detail for the voxel model during the shadow computation phase.

@radulphi I get it now, thanks. How would you solve the model cracking problem instead of by expanding the affected voxels? Wouldn't you're current method cause a loss of detail of viewed closely?

[radulphi]

@MakAttak101 Sry for the late reply (youtube didn't tell me that I've got messages). Answer to your question: Not necessarily. After being resized/stretched and before being drawn, the size of the voxel is evaluated. If the renderer considers it too big for the screen it will traverse the voxel's child nodes (if it has any) to achieve the desired level of detail.

@Ringwaul Blender is free and awsome, it includes fluid,smoke, cloth, and soft body simulations. You would have to learn python in order to try out your own algorithms. It is open source so may be able to find many different addons as well.

probably we don't know how to character rig via voxels...but does foliage won't crash/kill system to make real time rendering?

@Geoxile there is Qubicle Constructor and Slab6

@Ringwaul Voxel modeling doesn't mean the final product will be a "voxel model". 3D coat uses voxels for sculpting but in most cases it converts and outputs the sculpt as a poly mesh. I don't really see why you're seeking a voxel modeling program in particular, especially since there is little application for voxel models. There is always voxelizer
