Ben Lumumba Posted December 23, 2003 Share Posted December 23, 2003 Hi It's maybe strange question but I have to ask with a reason. In another 3D software if I model in 2 units,as 0.12, 1.45 up to 2.00 as lets say human I 2m high or 1.85,after some geometry editing and transformations the programm crash or causes creases in my models or at rendering time,or editing changes don't occure at all The reason is that after I model in 2.00 units,model editing of control vertexes,knots,points,weights... are in 0.009123 and that causes problems(for that metter in Animation Master or Electric Images Universe,but in no way that I critic or promote those programms ) So,I was suggested(on EI forum particulary) to model in 100's of units,i.e. in EI Modeler I model my character 200 units high,and than at editing level,changes occure in 1.5734, 0.25 or or alike,i.e. EI NURBS modeler you change knots weight,control cage weight editing,CV's ot points... or alike And the problem are gone Very often it is a case in weight editing,skin or alike So,I think when animating in Houdini,i.e. animal skin,weight ,mass deforamation or muscle simulation shouldI consider that or Houdini adopts itself to parameter changes Any suggestion?

Jason Posted December 24, 2003 Share Posted December 24, 2003 Hi Ben, We at DD always treat the units in Houdini as meters, and it seems to like working in that range of precision. I guess that you could stand to go up 10x or 100x if you pleased, but to establish some consistent space is quite important, especially if you're going to import models and such from other sources. Maya's default units are centimetres, I think. I think Johns remarks are quite correct, your issue is more about GUI sliders/handles than about technical precision.

Ben Lumumba Posted December 26, 2003 Author Share Posted December 26, 2003 Hi,Jason Just for your confirmation I created new geo with default x,y,z, value 1,1,1 and exported as dxf,(Alias) or obj. wavefront and when importing in EI Animator I had to zoom 10x times to get it in default view,than the same geo scaled 500 times got in EI at default view,weird I just use EI too. Read article about one of DD animator, Brian J. Pohl at www.electricimage.com/artists/pohl.html Happy hollydays Best regards, Ben Quote Link to comment Share on other sites More sharing options...
