What’s new Rigid Body Dynamics - SideFX
The DOP Import Field grabs all fields from a DOP network through Presets for saving them out to disk immediately. DOP Import 2.0 The DOP Import is used to get data out of DOP networks. The new 2.0 version is faster and has a more streamlined UI, while the parameters didn’t change.
DOP Import Fields - SideFX
Imports scalar and vector fields from a DOP simulation. The DOP Import Fields SOP is designed to streamline the common operation of importing many fields from fluid simulations into SOPs. Compression When importing simulation data, you may have extra attributes that you do not need to save to disk. The delete attributes will cull these attributes.
I don't know how to use "dop io and dop import". - Reddit
Dopimport is usually used to fetch or transform geometry based on a simulation. Something like a particle sim, rbd sim or a softbody sim. DopIO is usually used to import fields from a simulation. Mostly from fluid sims. So with a dopio you can import the density, temperature, velocity and any other attribute that you make. 3 [deleted] 3 yr. ago
DOP I/O vs DOP Import Fields - General Houdini Questions - od
Dop Import Fields is built to... import fields from DOPs. Dop I/O has built-in controls to automatically cache import fields to disk and then read them back, just like File Cache. It's a convenience node; up to you if it's worth using for your own workflows. 2 1 Author Posted October 31, 2025 Thanks Henry.
Dop I/O vs Dop Import : r/Houdini - Reddit
DOP Import is typically what you'd use for POP, Vellum, RBD, things without fields. They're specifically importing only fields or only the Geometry subdata from the simulation, which is what you'd use to render. This helps keep your cache sizes at a minimum.
- What is a DOP import field?
- This can also be the area where you can find the ball park the values needed in the shader to get the same look. DOP import fields isn't locked into just volumetric fields as under the hood most data groups are referred to as "fields" which is the Terminology they used at sideFX when creating DOP code.
- How do I import scalar and vector fields from a DOP simulation?
- Imports scalar and vector fields from a DOP simulation. The DOP Import Fields SOP is designed to streamline the common operation of importing many fields from fluid simulations into SOPs. When importing simulation data, you may have extra attributes that you do not need to save to disk. The delete attributes will cull these attributes.
- Can I import multiple fields with DOP import?
- Although you can import fields with DOP import you usually want to import multiple fields in the one go with DOP import fields, which also allows you to choose how the data is visualise. However this visualisation is very basic so you don't get what you saw in the Sim.
- What is DOP import SOP?
- The DOP Import SOP imports geometry from objects or relationships in a DOP network, or can create points representing the object’s transforms (for use with Transform Pieces). The Import Style parameter can be used to select between the different modes of operation. DOP objects have two distinct transforms associated with them.
- How do I select a field in a volume compress SOP?
- Each group can use the @name=density style group field to select the desired fields. Detailed descriptions of these options is found in the Volume Compress SOP. The DOP Network to extract the fields from. All the objects created by this node will be imported. This is the equivalent of the dopobjscreatedby expression.
- What is DOP import & how do I use it?
- DOP import is good to use for simulated objects where you just need to collect the transforms e.g Rbdsimulation with low-res pieces-> DOP import (import style: create points to represent Objects) ->transform pieces (moving hi-rez pieces)
