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
The scalar or vector field to extract from the object. It will be properly named, ie, the vel field will create vel.x , vel.y, and vel.z named volumes. It will also be in a group named after the DOP object. While this is designed around importing fields, any geometry can actually be imported here.
I don't know how to use "dop io and dop import". - Reddit
Dop IO or Dop import fields are needed to import fluid simulations. Especially when you want to import density, temperature, burn, heat, rest fields and all that goodness. DopIO also has a file cache node built in so if you want it cached you can use that. Dop import is for geometry importing or transforming. For particle sims or Rbd sims.
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.
What happens if you use dopimport instead of dopio or
You can import simmed geometry using DOPimport fields by of importing the dopnet-> the dop object -> enter the field "Geometry" DOPimport fields usually default to importing everything in the object so you'll see geometry without entering the field initially.
- 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.
- What is a DOP import?
- The key to understanding the DOP import is understanding the purpose behind each import style. The DOP import can simply import geometry from DOPs, and it can also apply transform data found in dops to things in sops. Also remember that in DOPs, your geometry is stored within your "objects" (ex: static objects, rbd objects, cloth objects, etc...)
- 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.
- Why do I need a DOP import node?
- Because it uses either the primitive group or @name, it allows you to speed up your simulation with low res, while applying the transform data to high res. -- If you use Fetch Geometry from DOP Network, then the DOP Import node will ignore anything that's connected to it.
- How do I use object transform in DOPS?
- This applies that data to the resulting sop object. -- In Dops, there is usually an option called "Use Object Transform" which tells the object to listen to any transformations that have been made on the obj level. If you check that box on, then you need to also be sure that is also checked on for the transforms to work properly.
- What happens if a DOP object is untransformed?
- When in transform mode, any primitives that do not have a corresponding DOP Object will be deleted instead of being left untransformed. This is useful if your solver deletes objects over time. In general, it advised to not rely on velocity when calculating motion blur because it will not curve. Instead, refer to the Curved Motion Blur quicktip.
