Hello All- Trying and experiment and not sure if it is possible. I have a cube with another smaller cube making a Boolean cut inside the large cube. I also have a blue cylinder sticking out of the cube (like a pipe sticking out of a wall). I would like the blue cylinder to be unaffected by the Boolean cut.... but as you can see by the picture, the Boolean cut effects everything (notice hollow area on blue cylinder). The question is, ....is there a way to make a Boolean cut selective to only one object in a scene, while ignoring other objects inside the "cut area"? (I tried playing around with different bone hierarchies but, no luck yet.) Thanks for any suggestions! Tom BooleanTest1.prj

Didn't know that...thanks!

You're probably right about the settings...and I wonder if there s any advantage or disadvantage of using one or the other...(?)

Thanks to Rob for another tutorial! BTW- I decided to compare the older "Rigid Body" and the "Bullet Rigid Body " using identical setups and there is quite a difference. I'm not sure why that is but it is something to play with. Tom Comparisons.mp4

Great explanation! Thanks!

Excellent, That fixed the problem! Thanks Rob! Why does that occur? Does the "target" exert some kind of force? Thanks for any info...

Hello Hashers- I created a simple project of some flat pieces of paper blowing away..... however in the first few frames, the entire group of paper bounces in the air. I can't figure out where the setting is that might cause those papers to bounce.. Any ideas? Many thanks, Tom bounce.mp4 BounceTest.prj

Interesting...thanks!

Thanks ...I'll check it out!

Thanks for the suggestions! The first suggestion sounds especially interesting. Can you demonstrate how to use an expression to link a slider to the Chor Glow Properties? That is beyond my ability... Tom

Another question which is unrelated to our discussion yesterday......but it has me stumped so I thought I would put it out there. I'm trying to create a pose slider to turn on a street lamp. Sounds fairly simple...I want the slider to make the outer" lens" of the lamp become about 35% transparent and I want the inner bulb to start glowing...all just by sliding the pose slider. The problem is the Glow feature seems to only have parameters that become visible WHEN you are rendering in the choreography.....so how do you set up a pose slider when the parameters you want to tweak only appear when rendering? many thanks for any insights...

Thanks Rob!

I have uploaded a very simple project which might present an area of discussion on Saturday Live. I am familiar with setting poses for "percentages" but I am less knowledgeable about Poses that are "On/Off". I am wondering if the topic for discussion can be adding an On/Off pose to this simplistic arm with one Pose being IK and the other Pose being FK..? PoseTest.prj

great insight! BTW- I dropped a note to Steffen and asked if there was a way to make Streaks cast shadows...will post his reply if there is.

very good...thanks for the reply!

Rob- I signed into the forums on my phone and didn't remember my user name password so it listed me as the guest... shown above... however, I would be interested in your personal opinion of when to use streaks and when to use sprites? What is your view of their strengths and weaknesses?

Thanks for the reply Rob! What is interesting is I was fooling around with trying to get streaks to cast shadows and I clicked on the little red "X" to opened up the drivers connected to the Streaks in the Choreography window and all of a sudden it looked like it was giving me the option to choose, "cast shadows" in the properties window...but when I went back to look for it, it had disappeared and I was unable to find it again...so maybe I was hallucinating or something. I will remember your method for the future but it might be a nice feature to have streaks cat shadows like the other particles.

Hello- I know that the particles listed as "Blobbies, Hair, Sprites,and Fluids" all have a "Cast Shadows" selection in their properties menu. I believe "Streaks" are able to cast shadows IF certain things are done. I believe it must be a Klieg light with ray traced shadows. There are also other steps one can take but the correct order escapes me at the moment. Does anyone know how to make Streaks "Cast Shadows"? Thanks! Tom

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?
