Playing with cloth sim. Using just the automatic vertex groups, for some reason changing the muscle slider makes the hat deform in odd ways.

I decided to try out this addon that lets you create loops in cycles nodes.
There's something naturalistic/biological about the results. Like splattered paint on a wall, or like a holographic material. (The one on the left doesn't use the loop node but it's there anyway because it looks cool.)

wow, iterations! Fractals... Thanks for mentioning this promissing addon.

Edit: I've got something for you: The Texture Mapping Node does not provide sockets to drive the translate-, rotate- or scale-values by say other textures, but we can replace its functions discretely: translating is just adding values to the x- y- or z-channels of the texture noodle,

Color ADD


scaling is multiplying the vectors by something,

Color MULTIPLY


and finally, rotating is a bit more mathematical (with sinus, cosinus and all the evil stuff),

the order matters


but luckily some smart people already did those replacements for us (look for the three nodes inside the blend).

Being able to drive the mapping is a powerful feature:

If you want to combine say a translation with scaling, just align them in the nodetree, one after the other, like adding up effects.

Whoa, good idea! I think that will be very useful.

Lately I've been trying to do perspective matching from photos (and anime backgrounds....)

I tried these addons for a while but it wasn't quite working out. Most of the time it would seem to match up with the perspective locally, only to deviate as you get closer to the edge of the photo.
https://github.com/stuffmatic/blam
https://blenderartists.org/forum/showth ... Rectangles

When searching for an alternative, the 3ds Max perspective matching feature looked good, so I went an installed the student version, just for that one feature.

(Google sketchup is also said to have camera matching, but google's search engine hasn't yet told me if that feature is available in the free version. )

The 3ds Max perspective matching has a better interface than in the blender addons. I figured I could use it to get the camera parameters, then create a similar camera in blender. 3ds Max specifies focal length and field of view independently though. Altering the sensor size to get them to match up didn't help. So I ended up making boxes in 3ds Max, and exporting them to blender. The results are pretty good I think, for something I whipped up in a new program.

Interesting. I experimented with the camera matching plugins available for blender a while back without much success. I ended up with a random scale or y being the up axis.

Inspired by titleknown's awesomely weird posts, here is some weird stuff I did earlier this year. I think almost all of it was done with the default targets.

Hair tool x blender + GMH2 x maya + $$$ + tinkering = generated textured polygon hair

Hair tool to generate the ribbon hair mesh, and GMH2 to create and bake the procedural hair texture. (the human was not made by me, and comes with the hair tool addon. the hair strips were generated from one of the base mesh hairs in the addon, too.)

I think there was supposed to be a way to fade the edges off each hair strip, but I have to figure out what that was. (other than the cumbersome method of using rotated gradient textures.)

If I learn how to get better results, i could do more of these. But since my maya is the educational version, the textures could only legally be used for personal non-profit uses. Still, if anyone reads this post and wants this hair, I can export and send it. (both hair plugins can also produce actual physical/realistic hair tubes, but those would be harder to add to MH, I think. )

I also need to try using the new surface deform modifier from 2.79. It could potentially be used to have cloth sim of the base mesh drive animation of the fancy generated hair mesh.

Sounds like this has some potential, having more hair assets would really be great. I hope there are some hair textures out there with CC-like licenses, it seems like something that should exist. Are the textures from the current MH hair assets of any use with these tools?
