Mash local transformation

[Anonymous]

Hello, 

is there a way to make mash use local transformation, instead of world transformation?

I have imported some objcts that came in their right position i wanted to use the expolde node, to make they grow using a falloff, but the problem is that all the transformation originates from the world center.

Hi Giorgio,

I haven't worked with the explode node much, but have you tried doing a Modify->Freeze Transformations on your imported objects before you apply the MASH node?

Hello, pshwayka!

Yes i tried that, but all the transformation happens in relation to the world coordinate. I also tried that trick, grouping the objetc, it did not work. 

Thank you!

Btw, that problem occurs not only with the explode node. I think its kinda of a limitation of mash plugin?!..

Okay...I had a few minutes to play around with this. I see what you mean. The only way I found to make an explosion local to an object away from the origin was to create the explosion at the origin and then move it to another location in the scene.

Sorry...I know that's not the workflow you wanted to use.

Yes, and thats the problem!! Actually to make this work, we need to "rebuild" the scene completly 😞

Ok, i ve got the solution from Ian Waters, its simple, just bake the pivot point befora you create the mash network!!

Nice!  Right from the chap who created it.  Thanks for posting the solution.  I am really wanting to get into using MASH so it's good to know some of the gotcha's first.

Strange...I can't get that to work. I've imported a basic poly sphere that was saved in a position away from the origin, and if I bake the pivot and create the MASH network, it jumps back to the origin. Am I missing something?

It's weird that the solution came from a NEW MEMBER with a vary similar name to the original poster.  What's up with that?

[pshwayka]

Ha! I didn't even notice that...good eye.

Interested to see if the solution works for the OP.

I have 2 accounts here, and i forgot to login with the orinal account from the original post.. I am sorry!

To make this work, you need to use the inial state mode.

I figured it was something like that.  Thanks for the update.  Let's see if pshwayka get's that to work.

[pshwayka]

Ahhh...much better. Thanks!

[pshwayka]

FWIW....I'm finding that if I use the initial state mode without having baked the pivot before creating the MASH network, the explosion seems to work just fine. Have you tried that? (Sorry to bother you again.)

[giorgioadolfoQPPNU]

Yes i tried that, but all the transformations were related to the center world. And after baking the pivot, they were local. Another thing i noticed, is that after you bake the pivot, create the mash net work, theres no way to change the pivot and bake it again, it will mess all the transforms. So you need to delete the mash network, change the pivot were you want, bake it, and create the mash network.

Hey I just created a sphere, then with a cube a created a mash network and used the sphere as a mesh, then added and audio node, I want the cubes to go away from the normal with the audio, but theys just go up in y, I checked the local transform, but doesnt seem to work, any ideas?, I have all baked and freezed transforms, I even grouped the cube. thansk
