Hi Roice,
Thank you, now it makes sense. So starting edge for "EndRotation" is unpredictable?
I made four puzzles based on {10,3}. Three of them are copies of spherical and hemispherical puzzles and one (18 colors) looks like new one. Configuration files are here: https://www.dropbox.com/s/j32xshxy0nefk46/%7B10%2C3%7D.zip https://www.dropbox.com/s/j32xshxy0nefk46/%7B10%2C3%7D.zip

Hi Andrey,
Sorry for the delay. I was camping this weekend and disconnected from the interwebs.
To find working values, I looked at your file and compared your coloring configuration to the one for the hemidodecahedron. Two tags needed to be changed:
"UseMirroredEdgeSet" needed to be set to false. That is true by default, but I’ve noticed it generally must be false for non-orientable puzzles. The hemidodec also had "EndRotation" = 1. Here is a working file, which only differs from your file by those two tags:
http://www.gravitation3d.com/magictile/4d_cubing/%7B10,3%7D%206C%20edited.xml http://www.gravitation3d.com/magictile/4d_cubing/%7B10,3%7D%206C%20edited.xml
I wanted to note that there was one required alteration to the hemidodecahedron coloring config. The elliptic puzzle had "InitialEdgeSet" = 1, but for the hyperbolic puzzle, this needed be left as the default (initial reflections across all edges) so it could fill out the whole plane. It is so interesting how the spherical puzzles can be expanded to hyperbolic tilings.
Hope this helps!

Roice,
can you help me with this example: https://www.dropbox.com/s/bkb1runsvpyzooh/%7B10%2C3%7D%206C.xml https://www.dropbox.com/s/bkb1runsvpyzooh/%7B10%2C3%7D%206C.xml ?
It gives correct pattern of white faces, but keeps saying that all other tiles have the same color. But there should be 6 different colors (it’s hemidodecahedron expanded to {10,3}). I tried different values of EndRotation, but they don’t help. What do I do wrong?

Here is the documentation page for configuring colorings (made for Eduard a while back):

I’ll be the first to admit that creating new colorings is not the easiest thing. I’m happy to answer questions though, or to discuss how it might be improved.
Cheers,
Roice

OK, good to know, thanks Andrey. It surprises me a bit that puzzles with more colors are harder. That seems counter to the pattern where for example, the Rubik’s cube with 6 colors seems harder than the Megaminx with 12. Hopefully Roice will jump in with additional documentation on his puzzle file format. I would like to see what sort of fascinating new puzzles you come up with.

Melinda, I’ve solved some of puzzles a couple of months ago, but there was nothing new for me - just versions of tetrahedron and cube. For something new we should try new coloring (with 12,24,36 colors etc.). Unfortunately I don’t understand Roice’s notation of puzzle definition, and can’t add good puzzles to MT.

Dear Cubists,
It’s been a while now since Roice added several (approximately) infinite
polygons to Magic Tile under "Hyperbolic > Large Polygons", and I’ve not
seen or heard of any solutions to the ones with more than three colors.
Has anyone done that? Even with 5 random twists I find myself hopelessly
lost, but then I’m not a strong solver. These new puzzles sure look
fabulous. How do they compare to the rest?
