I'm setting up a project where I need to rotate and move large objects in modeller. Are there any plugins that can replace objects with bounding-boxes on the fly?

Set Open GL transparency Off and you will big speed improvement while manipulating large objet in modeler…

odtools has one.

Thank you for input... pixym, OpenGL transparency was already turned off :/ Asticles, the plugin you mention is for LW Layout.

You can divide the object into parts and save them separately to work on a certain section of a large object without the modeller's lags. There no instances function for modeller yet.

in Modeler, no.

not solutions, however, 2 tricks...

moving objects to Layers can help, if applicable >

Thank you, however it's not OpenGL speed that is the problem. It's mesh manipulation thats slow, and in Modeler rotation and movement is a mesh manipulation, unlike many other 3D-programs. To make matters worse, mesh manipulations is quite slow in Modeler, I tried the same object in Maya, and editing the mesh was much faster in Maya. However, Chronosculpt is quite fast (super fast when just editing points, but slower when transforming the entire object).


Does anybody know if there are any plans for integrating the Chronosculpt mesh system in Lightwave?

at this time, no.

there have been substantial upgrades to Layout, where part of the code got integrated, that's all we know.

the Modeler road-map is a bit uncertain.

blender?

Actually, I downloaded Blender after your post, to check it's speed with the same operation, but it was unable to open the FBX-object (!?). Neither Modo, Maya or Chronosculpt had any problem with the object.

As blender is open source and fbx is not an open format blenders fbx support is a bit picky and doesn’t open all fbx files. Try to resave the fbx in another version and try again.

I just loaded a fbx in blender from rhino v.6 today with 47 million polys and it worked perfect.

Unless, of course, they're into that sort of thing. :devil:

I'll just add, that edit heavy objects in Blender is not faster than Lw. Blender handles large object quite good in object mode (like layout) but in edit mode (like modeler) its just too slow if you have medium to high poly models. I think without tested myself that Maya may be the king, if you want to edit large poly models.

manipulating a fbx with 5 million polys.


Blender

Import file: 1 min 46 sec
Select one point: 7 sec (time for click on point until it highlights)
move point: 14 sec (time for start move mouse until the point actually move)

LW 2018

Import file: 35 sec
Select one point: 1,6 sec (time for click on point until it highlights)
move point: 8,5 sec (time for start move mouse until the point actually move)

Something needs to be done with this. In Chronosculpt it's almost instant. The lag of working with large objects in LW is a problem these days. Both final render and live OpenGl-view are up to speed on modern computers, while object manipulation is so slow that it hurts projects and working hours.
