So I solved it by make file->new asset and make it python type and write like

and then use boolean to export selection.

worked like a charm!


script like this

def onButtonPress():
    node = hou.pwd()
    geo = node.geometry()
    
    #group Node
    Box = hou.node('/obj/Dressing/box1')

    BoxSize = 100
    BoxX = -100
    BoxZ = 350

    #fbx node
    fbxNode = hou.node('/obj/Dressing/fbx_out2')
    exportPathBase = hou.parm('/obj/Dressing/exportLevel1/exportPath').eval()
    Index =1
    Level = "Level2"

    exportButton = hou.parm('/obj/Dressing/fbx_out2/execute')
    
    #looping and exporting
    for x in range(0, 6):
        for z in range(0, 6):
            #update group selection
            Box.setParms({"tx":BoxX+x*BoxSize,"ty":0,"tz":BoxZ-z*BoxSize,})
        
            #update fbx node and export
            newExportPath = exportPathBase+str(Index)+".fbx"
            fbxNode.setParms({"sopoutput": newExportPath})
            exportButton.pressButton()
            print newExportPath
            Index +=1
          
    
    hou.ui.displayMessage("------------------->Export Finished<-------------------")

Hi!

Here you can se empty fbx files in Unity. Its supposed to be a complete square!



I have a big mesh I need to slice up and export multiple fbx files instead of one. I have a solution but it is not stable. Often fbx files are empty! This is my solution to export multiple fbx files. I press Animate frames same amount as I have fbx files to export. If you have som light to spread on this matter, then I am very grateful! Example scene is able for download. thanks!

Houdini Engine for Unity » Smart way to populate Unity GameObjects to Inputs on HoudiniAssetOTL (DigitalAsset)

So I solved it to tag all the collider objects and with this code populate the list “prUpStreamGeoObjects”

static void PlaceColliderToScene()
{
//get all colliders in scene
sceneGameObjects = GameObject.FindGameObjectsWithTag(“Collider”);
curObj = Selection.activeObject as GameObject;

curOTL = curObj.GetComponent<HoudiniAssetOTL>();

for (int i = 0; i < sceneGameObjects.Length; i++)
{
curOTL.prUpStreamGeoObjects = sceneGameObjects;

}
Selection.activeObject = curObj;
}

Hi!

(100 is just a random number, it need to be dynamic)

So I got 100 GameObjects in Unity Editor Scene with tag “Collider”. I have made a Digital Asset where there is a merge inside and 100 inputs for all of them.



Instead of drag and drop 100 times that also will happen multiple times I want to populate it with code. I'm almost there I think. It seems like I need to convert my GameObject to HAPI_Transform. I'm stuck.

Does anyone have any idea please? :-D

this is c# code in Unity

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;
using Houdini;

public class CollectTagColliders : EditorWindow
{
    public static CollectTagColliders curColliderWindow;
   // public static GameObject curDGA_ColliderAsset;
    public GameObject curColliderParent;
    public static GameObject[] sceneGameObjects;


    public static GameObject curObj;
    public static HoudiniApiAssetAccessor curAccessor = null;
    public static HoudiniAssetOTL asset;
    public static HoudiniAssetOTL curOTL;
    public static HoudiniParms curParms;
    public static HAPI_ParmInfo[] parmInfos;




    [MenuItem("Spelprojekt 8/CollectColliders",false,7)]
	public static void InitWindow ()
    {
        curColliderWindow = (CollectTagColliders)EditorWindow.GetWindow<CollectTagColliders>();
        GUIContent titelcontent = new GUIContent("ColliderTool");

        //get all scene GameObjects with tag Collider
        sceneGameObjects = GameObject.FindGameObjectsWithTag("Collider");

        
    }
    private void OnGUI()
    {

        if (sceneGameObjects.Length == 0)
        {
            GUILayout.Label("There is no Collider Tags in scene");
        }
        else
        {
            if (GUILayout.Button("Print All Colliders in Debug", GUILayout.Height(40f)))
            {
                for (int i = 0; i < sceneGameObjects.Length; i++)
                {
                    Debug.Log(sceneGameObjects[i].name + "  index--> " + i);
                }
            }
            if (GUILayout.Button("Print All DGA params", GUILayout.Height(40f)))
            {
                PlaceColliderToScene();
            }
        }
    }

    static void PlaceColliderToScene()
    {
        string assetPath = Application.dataPath + "Assets/DigitalAssets/B_addon_Collider_Parent.otl";
        curObj = new GameObject("B_addon_Collider_Parent");
        asset = curObj.AddComponent<HoudiniAssetOTL>();
        curAccessor = HoudiniApiAssetAccessor.getAssetAccessor(curObj);
        asset.prAssetType = HoudiniAsset.AssetType.TYPE_OTL;
//        asset.prAssetType = HoudiniAsset.AssetType.TYPE_INPUT;
        asset.prAssetPath = assetPath;

        asset.buildAll();

        curOTL = (HoudiniAssetOTL)asset.GetComponent<HoudiniAssetOTL>();
        Debug.Log(curOTL.prObjectTransforms.Length + " geo count!! ");

        Debug.Log(curOTL.prGeoInputCount + " geo total slot count!! ");

        curParms = asset.prParms;
        parmInfos = curParms.prParms;


        for (int i = 0; i < sceneGameObjects.Length; i++)
        {
            curOTL.prObjectTransforms[i] = sceneGameObjects[i];
        }

        Selection.activeObject = curObj;

    }
