Pyro look development - SideFX
To get the exact temperature range of your effect, import the temperature field into a geometry network using the DOP Import Fields or DOP I/O surface node and turn on Compute Min/Max on the node. This creates primitive attributes on the field containing the minimum and maximum value of the field.
DOP Import - SideFX
When importing DOP Objects as points, this option is disabled. The DOP Object overall velocity is always assigned to the point representing that object. The Transform Pieces SOP can create a velocity point attribute on the transformed geometry. Parameters DOP Network The DOP Network to import objects or relationships from. Objects
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.
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 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 happens if I use fetch geometry from Dop network?
- If you use Fetch Geometry from DOP Network, then the DOP Import node will ignore anything that's connected to it. In this situation, it will simply just import all the information found inside the dop objects. -- Do not use this parameter because it is depreciated. -- Don't know what "packed" geometry is?
- 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 import geometry from a DOP object?
- The subdata path for the geometry to import from the DOP objects. This can be a pattern or list of subdata paths to import geometry from. The same data path will be used for all source objects. If left blank, the object’s Geometry subdata is used. Creates a packed geometry primitive for each DOP object or relationship that is being imported.
