Could anyone tell me how you reset the dyn?

When i hit play i get strange behaviour, when i rewind i also strange behaviour, like dyn is not reset to default/start position of hair, looks like it only resets when i scroll timeline with a mouse??????

I have been in fx world for more than 10 years and non of the dyn engines/systems were reset this way?! So if anyone could tell me how this thing works would be great :), btw i watched all the tutorials on ornatrix...

 

thanks

 

Are you trying to reset pre-recorded dynamics or live dynamics? Going back one frame will reset the live dynamics.

well im trying to play the time range, and when i click on << rewind button in maya, hair doesnt reset to start possition, maybe it was a problem with DG mode? i mean ill try to switch to DG mode and try again...

let you know asap

cheers

nope not working as im expecting :)

and its not the probl with DG, definitely something is wrong or im not sure i know how to use it...

i will record a video, i think thats the best...

I suppose this is the same issue as the other thread, I will post there.

The reason the hair is already deformed at first frame is because one dynamics step is already when you add the operator. I might change this.

For me, if I scroll the timeline, scrubbing back in the resets the simulation properly. If I click the go to start button in playback controls I get the same behavior as you: hair shape resets but the dynamics doesn't. I will look into this. Meanwhile please try scrubbing through the timeline by dragging it.

I understand what you are trying to say, but thats not the way that dyn works, you cant scrubb the timeline with mouse, what will happen if u scrubb a bit more than you should, like skip 5 10 50frames, what will happen with dyn?

if you want my advice, please remove everything related to scrubbing, and the only control that user should have are the player controls, Play, Stop, Rewind...

cheers

Scrubbing is more for a real-time preview not an accurate reflection of the result. Recording the dynamics is a better way of getting the result. I will have a closer look at the controls.

i mean, its stupid, what am about to write/say, but take a look at the other hair systems and see how their dynm work :)

cheers

Thanks for the tip. Aside from what you already mentioned, do you have any specific things you want to see?

Let me play a bit more, these are 1st impressions when i started using dynm.... :)

you are already crowded with stuff to be done, from the video i send you, so if its ok with you we can go step by step

 

cheers

 

Please check the latest nightly (8833+). I fixed the scrubbing bug when using the go to start buton. Also another issue with clearing recorded data is fixed.

Hi Marsel, i already did, and i think i have the same problem i had before... It was late last night when i tried but it looked to me like nothing was fixed, but let me check again, and ill let you know

When try orn hair dynamic I have some problem .....hope fix it  ,or add a start time for dynamic

Hi guys, i finaly got some free time to check out the latest build, and not sure i can say i like anything about the dyn...

 

here is a video, and desc:

so, when you hit play and dyn starts and you leave it like 10-15f to calc, when you rewind to 0 and you hit play, hair starts from that last 10th frame as a start point????? Im not sure i understand this part, why does it takes the last calc frame when you rewind/reset it?

Thank you for recording the video. Did you try this in the latest build? I thought I fixed this problem, I will make sure again. Do you get the same problems when hitting record button?

Hi Marsel,

i think its the latest one from few days ago, ill download it again and try..

let you know in few min, just to download it again :)

cheers

yes its a latest ver,

but you are right it doesnt record the preview issue with taking the latest frame as a start point, sorry for false alarm :)

cheers

p.s. moving forward, and testing other interesting stuff in this great plugin ;)
