Re: ICE - How to quickly build low-poly geometry on high poly meshes
Polygon reduction does a pretty good job for this kind of thing really especially as you can preserve volume etc. Maybe you just need a basic script? Select some objects, duplicate, rename apply poly reduction to them? Would that be enough?

Thanks Simon, I'll try it out soon as possible, and I'll take a look at the script to see whats going on there :) Thanks again! 2013/12/18 Simon Reeves si...@simonreeves.com Actually mine didn't work with multiple objects as it reassigns selection during the script, school boy error here it is fixed http://pastebin.com/hxTjBvLr Simon Reeves London, UK *si...@simonreeves.com si...@simonreeves.com* *www.simonreeves.com http://www.simonreeves.com* *www.analogstudio.co.uk http://www.analogstudio.co.uk* On 18 December 2013 12:20, gareth bell garethb...@outlook.com wrote: try this ( I hacked some of from Steve Caron's script here - https://groups.google.com/forum/#!msg/xsi_list/-mDMXnp28aI/9YB0ue8xP9AJ ): import win32com xsi = Application coll = win32com.client.Dispatch( XSI.Collection ) coll.AddItems (xsi.Selection) #get first objects name so you can use it on the new mesh once it's made meshName = coll(0).Name ops = xsi.ApplyGenOp(MeshMerge, , , 3, siPersistentOperation, siKeepGenOpInputs, ) # ApplyGenOp returns a collection, if there is a count then the operator was successfully applied if ops.Count: op = ops(0) op.tolerance.Value = 0 # get new merged object mergedMesh = op.OutputPorts(0).Target2.Parent xsi.ApplyTopoOp(PolygonReduction, mergedMesh, siUnspecified, siPersistentOperation, ) #name the new mesh mergedMesh.Name = str(meshName) + _merged -- Date: Wed, 18 Dec 2013 12:53:49 +0100 Subject: Re: ICE - How to quickly build low-poly geometry on high poly meshes From: 3dv...@gmail.com To: softimage@listproc.autodesk.com @Simon: Yes, for my purpose that would be enough I'll try by best to create a simple script that allows me to do that, and also adding a shrink wrap which is a good advice ;) In case I'll bother you guys with some help for the script :D Thanks 2013/12/18 Mirko Jankovic mirkoj.anima...@gmail.com can also even add another shrink wrap on top of it to get reduced mesh closer to original one if needed On Wed, Dec 18, 2013 at 12:33 PM, gareth bell garethb...@outlook.comwrote: Yes, I agree with Simon on this.

Select some objects, duplicate, rename apply poly reduction to them? Would that be enough?

I'm doing something similar by duplicating by meshes, join some of them together, and then apply the polygon reduction tool in order to have a low poly mesh of the object I would like to make a quicker way to create low poly meshes, maybe by creating a compound that can be shared among the high poly meshes ( or applied to a group of meshes ), and if possible be able to rename the created low poly mesh with a suffix named UCX_ ( which renamer do you suggest to batch rename meshes?) I haven't tried yet to build geometry in ICE, so I was wondering if something like this can be done quickly in ICE Cheers -- www.matinai.com
