Hey ppl! I'm trying to extract transform, scale and rotation from one geometry and apply it to another with VEX. In my case I'm extracting from a grid (2nd input) and applying to heightfield (1st input) which only takes Y rotation. Help me figure it out? Thanks! transform.hipnc

I'm trying to make simple patterns/tessellations like the first image (randomized 1 axis rotations, etc.). But my geometry won't lie flat or line up with the grid. I've tried many different orient values, but I can't seem to do a simple 1 axis rotation. It always looks like I spilled potato chips on the ground. Am I just using the wrong quaternion values or is there something wrong with each shapes anchor point? Do I need to nest each triangle in a square plane before rotating them? triangle_grid_v4.hiplc

Hi! This is like a mixture of rigging and effects. I'm trying to add some cool dynamic parenting behavior to a working system that I have (the inputs from the locked null) but I hit a wall and I can't figure out how to solve my problem with all the attribs that I have (I created custom attribs for the Transforms). The problem is that I cant get the parenting to work with my current logic, I failed I used a dirty trick that gives me what I want but its just for that geometry with that size and distribution, so yeah its not really useful but at least it gave me a clue, but I'm still lost. Maybe some magician can help me out with this! Thanks! I'll share the file. PolyTransforms_Problem.hip -
Hello, I'm working on a project and I'm a bit stuck on matrix transformation. I don't have a strong background in matrix manipulation. Here is what I am trying to do: I have a packed alembic that has been created from an external program. The alembic has a fullpackedtransform intrinsic that contains my translate, rotate, scale and shear data. I want to shatter this alembic geometry, pack the shatter pieces and use the original alembic transform to animate the pieces which will then be input into a rigid body simulation. I'm having trouble extracting the relevant data from the 4x4 matrix on the alembic. I can get my points to translate, but I don't yet understand how to make them rotate. I hope my diagram makes sense.

Hey guys, I have been having troubles with extracting transforms from an incoming alembic and apply it its vdb. My guess is, that you extract transforms using transform matrices in VOPs and apply it to the position of the vdb. But I don't know how. Can somebody help me with it please? -bf -
i have a object level DA which suppose to accept multiple inputs from nulls and build a curve inside the the asset. my problem is the first object will serve as the parent of the DA and it moves the whole container. is there a way to prevent that behavior inside the asset like how the muscle object node handles multiple inputs?. or another node that came to mind was the fetch node option "use parent transform of this node" toggle.

Hi there. I got this setup for a dandelion which works perfectly, but then I collapse everything into a subnet. Now, if I move the subnet around, the particles sim doesn´t work properly. I looked inside and both the emitter and a group bounding object seem to be transformed more than the rest of the subnet. Is it a bug that I must report or am I doing anything wrong? Could you guys take a quick look. It´s all setup already. StrangeParticlesCoordinatesProblem.hipnc
