UE .csv import Nov. 16, 2018, 11:45 a.m.

It's a conflict with how UE4 wants to use csv data. Just change your extension to .hcsv and you should be good!

RBD Sim - Issue with sub-object rotations when exporting from vertex_animation_textures (UE4) Nov. 15, 2018, 1:14 p.m.

Hi. I made a couple changes to your file.

1. Object merge all the geo from the fbx import. This is a lot easier to manage than the bazillion nodes you have coming into the dopnet. This also sets up the local space of the transforms which could have been causing the issues you were having with everything ending up at the origin.
2. Use a dopimport to extract the sim geo to a geometry container and use that as your export. I think pointing to the dopnet directly doesn't play nice with the Vertex Animation Texture node.

GameDev Tools Updates Nov. 12, 2018, 2:56 p.m.

09 Nov 2018
New Tools
  • Adding UV Transfer SOP and UV Fuse SOPs
  • Adding OSM Filter Node

  • Changed how override of number LODs in LOD Hierarchy works. Tool no longer requires user to manually set number of LODs for export to get the number of LODs to be the number of inputs.
  • Made detail mesh more robust. It will convert the tile mesh to polygons before trying to project it.
  • Added Alpha to MotionVector shader in viewport.
  • Adding Reality Capture Plugin to the GameDev Tools. Minor Updates to Mapbox, Readding missing parameters on AO node and adding switch to enable merging small islands on gameres node
  • PhysicsPainter added volumetric brush feature
  • Changing some defaults on Measure Curvature and Color Gradient, and reworking Calculate Occlusion with better logic
  • Animation Impostor Improvements
  • Added concave support for Static Input Mesh. (Resolves issues with very uneven terrains producing useless collision meshes) Also added support for Convex Decomposition in H17 PhysicsPainter HDA and example hip
  • Adding some better error handling for cleaning up meshes before sending data into Zbrush
  • Removing hard coded file1 deletions
  • Resaving VoxelMesh for 17
  • patching up gameres node
  • Adding new UVAutoSeam to AutoUV SOP
  • adding GoZ to the shelf
  • VAT: Updated parameter names to work in Houdini 17.

Bug Fixes
  • Games Baker - Fixed long time gamma issue for greyscale maps such as Roughness, Metallic etc Simple Baker - Swapped old material assignment logic with Quickmaterial. Will now be a more accurate representation of pre-bake. This also fixed the flipped normal Y in viewport bug LOD Create - Above fixes benefit tool overall. LOD after material consolidation looks more like LOD0 now.
  • Fixed LOD Create Permission err0r when using the tool to extract source textures checked into perforce. (Files being read only)
  • Simple Baker solved Cage issue. Also fixed resolution parm
  • Fixed no cage issue for custom export channels in Games Baker
  • Mesh tiler fixed post solve attribute cleanup. Will not delete any user attributes such as Cd anymore. Also updated demoscene to include a color example.
  • Fixed render issue in H17 LODCreate. Added LOD Debug option.
  • Fixing unit test issues with Calculate Occlusion node, and some cleanup of the Mapbox node
  • Fixed bug in QuickMat. Multiple materials supported again.
  • Fix GoZ for Houdini 17
  • Texture Sheets: fixed flip green attribute name
  • Fixed turntable tool. Rotate around Origin toggle was not hooked up to logic.
  • Fixing cage bug in Simple Baker
  • Fixing several broken commands on the shelf
  • fixing principled shader warnings on osm buildings node
