no problem...take your time... there are always little things to pick up along the way.

Thanks to Rob for another Live Saturday tutorial! I agree that the Oswald cartoon was artistically superior to Steamboat Willie...interesting observation. Thanks for pointing it out. BTW- Is there any chance of you posting the video of today's class?

OK ..thanks..

I only have v 19 on my computers... If you are so inclined, maybe you could try it on 17 tomorrow(?)

I'm guessing the fluid properties can be animated so the gravity is normal and then zero gravity takes effect when the blob hits the surface ...

I didn't know that was possible... Will that effect everything in the scene or just the specific blobs?

Yes, his "action" paintings were all done horizontally but I was just looking for an example to describe the animation of something splattering against a wall or other vertical thing. Do you think that is possible to make a blob (or other particle or sprite) stick to a vertical surface?

I have been trying to figure out how to replicate a character flicking paint off a paint brush onto a canvas. Think, Jackson Pollock onto a vertical canvas. I can sort of figure out the flicking of blobs but I don't know if it is possible to make those blobs stick onto something... Anyway, I hope to be there tomorrow. Tom

Rob- Discovered that the Simple Scatter Plugin allows the user to fill various shapes using a drop down menu. We were puzzled why some of the leaves dropped through when we were filling a circle. Excellent that anything can be filled!

great effect!

Very cool! That approximates what Andy was showing us yesterday! So you are just changing the size of the funnel over time? Or just adjusting the size of the Magnitude?

Thank you!!

Interesting...will give it a try. And thanks again for hosting the session today! BTW-Are you able to post a recording of the session today? I always find little steps and tricks that I missed the first time...

Here is the new leaf project rendered to 400 frames. As you can see there is not the cyclic quality of the v12 version. I wrote to Steffen and asked if it was possible to reproduce the original version where the leaves cycle continuously. BlowingLeaves.mp4

Thank you! Very smart to turn off particle collision and leave object collision on!! I never would have thought of that! Thanks again! Tom

Hello Hashers- I had an idea of leaves being emitted as sprites and I wanted those leaves to swirl in a curlicue past the camera. I created a curlicue model as a guide for the sprites to follow and made it 80% transparent so I could see if it was working, and if it did work, I would make the guide 100% transparent for the final render. I made the sprites react to collisions and thought I set everything properly. I even had an animated force fanning the sprites inside the tunnel. The force moved one leaf but the others stayed behind. Unfortunately all the leaves glommed up at the beginning of the "wind tunnel guide" as you can see from the video. I wonder if there is in fact a way to direct the path of moving sprites along specific areas? Many thanks for any help! Tom WindTunnel.mp4 WindTunnel.prj

cool... If I come up with any interesting I will post it! Thanks! Tom

Interesting videos! It occurred to me that the "GreenGas" project you created a while back looked very cool. If you could somehow have the streaks hanging in the air then a vortex force could swirl them around as a character walked by. The only thing is how would you get those streaks to "hang in the air" long enough? Maybe have a very slow emittor on the ground like mist rising? Maybe a Saturday Live Chat topic?

Nice flash light effect... So if you have a misty graveyard scene and Frankenstein (or Thom) walks through it, the mist will not part or swirl around the character? That will have to be done with some sort of particle setup?...and I have no idea how that would be achieved...

This is off topic to what we were discussing above..... ...but I was playing around with Dust,Mist and Steam this morning and it looks like none of those are affected by "Forces". Is that a correct assumption? I'm guessing that "Forces" need some sort of particle to affect for "Forces" to work... I'm thinking about animating "wind" and I'm guessing it needs to be some sort of particle for it to animate...(and be visible) Do you know if anyone has done a "wind" project? Tom

Thanks for posting! An interesting comparison. In the Disney animation school I've heard that the fledgling animators have to make a bouncing, 1) Bowling ball 2) Basketball 3) Ping pong ball to show they understand the significance of spacing. It might be a fun exercise to try adapting the parameters on those three balls to match the Disney test. Thanks again. Tom

Thanks again to Rob for hosting another session which upped my AM IQ! I received a nice reply from Steffen with an updated version of the leaf blowing project using Bullet. His reply is shown below with his attached new project! From Steffen- "Select the Choreography , than -> Plugins -> Wizards -> Add Bullet Constraints to multiple models -> in the plugin dialog set the Hulltype to Box and hit Select all , hold down ctrl and left mouse button on Shortcut to Ground (to deselect the ground) and than create . This will create the needed bulletconstraints for the models . Than You can simulate. Maybe you need to modify some values for the constraints . This can be done with another plugin . Selected chor -> -> Plugins -> Wizards -> Modify Bullet Constraints on multiple models" Blow_start1.prj Leaves1A.tga

All excellent suggestions! Will have to play around with those ideas... (That errant dollar bill sticking behind must be due to inflation!😄) I know he is very busy but I did write to Steffen and asked if he was able to update that leaf project ......because it is SOOOOOO Cool! What he had going on with those Forces is remarkable. Thanks again, Tom

Many thanks for taking the time to troubleshoot this! I might contact Steffen and see if he is able to clarify how it would be done in the new build. Tom

Yes, the one I posted was re-saved in v19. I found the original zip file and it was from 2006 !!!.(attached) It still beggars the question of how can a v19 user recreate the simulation that was set up? Or does a person need to start from scratch? leaf.zip
