Paint Ball

[tinmanjuggernaut]

I'm working on a short motion graphics demo of a ball of paint bouncing around a room (or maybe a paint covered rubber ball). Here are some pics. I'm not using physics, but rather hand keying the bounces and stretching of the ball.

#2 and 3 shows my progression of a brass type material on the lamp. #2 I couldn't get it quite right, it looks like some cheap painted tinny material. Then I realized I needed colored instead of white reflections, which you can see in #3.

These are low quality renders and there is lots more to do.

The hand rail and floor will be smoothed and reflective like polished wood.

What do you think of the wall texture? #1

Also what about the ball? I want it to look wet; ideally like a gallon of liquid paint that is held together in a ball shape by some force. Right now it's such a perfect sphere that it looks hard. It's fine for a rubber ball, but I'm thinking about a slightly jelly ball. If paint were held together by some force and could bounce around, how might it look on a still frame in between bounces? Maybe a subtler version of that jelly material I posted in the material library?

Fortunately dynamic paint will take care of all of the paint splotches on the environment when I get to that point.

Re: Paint Ball

So Dynamic Paint already works fine or need some additions to script?

Re: Paint Ball

The script needs the ability to handle image sequences as texture maps in animation mode. Even though the option is there, it only works properly for stills.

Dynamic paint and the v-ray exporter don't need to interact with each other. Dynamic paint bakes it's textures into an image sequence. Then if I export and render say frame #40 of the animation, frame #40 of the image sequence is properly mapped onto the object, 41 for 41, 42 with 42. However if I check the animation button, then export and render, every frame of the animation uses the last frame of the image sequence. e.g. Frame 40 of the animation, uses frame 100 of the image sequence, Frame 41 uses frame 100 of the image sequence, etc.

Also, unrelated to dynamic paint or image sequences, often when I click the render button in animation mode, it plays through several frames, or all the frames, then causes blender to crash. If I reopen blender and run it again before doing anything else it often will work. However sometimes I have to render only a handful of frames at once because of this.

Re: Paint Ball

Hm... don't know sequence was broken - fixed =)

Re: Paint Ball

Hi, this etude "sounds" interesting. I can think of this ball as a balloon filled with water - to behave flexibly to the max...
I like this slick shine on the ball surface, and I would like it also in final effect.
But I would divide the scene to two styles of visualization: 1 - the ultra realistic one for the ball and key actor objects - paintings, artworks, etc.
2 - very basic, but very aesthetic shading for the interiors (maybe toon?)
that would give a contrast and lead the spectator to the most important content of the video.

I don't know what the detailed motivations for the aesthetic style are in this case. So these are not "must have/must change" suggestions.

Re: Paint Ball

Interesting ideas, thanks!

Last night and this morning I rendered a first pass of the animation with AO so I could see where I'm at with it. Lots of work to do! This has been slowed down a little
