Hi all, I’m using a multimaterial with the following pattern:

**var materials = [ material1, material0];**

**myObj.geometry.clearGroups();**

**myObj.geometry.addGroup( 0, Infinity, 0 );**

**myObj.geometry.addGroup( 0, Infinity, 1 );**

**myObj.material=materials;**

This works fine but not in case of intersecting objects with raycaster

**var intersects = raycaster.intersectObjects( myArr,true );**

The reason is the Infinity parameter, which brings the ‘end’ variable to an infinitive state an in turn the following for-loop never ends and the browser hangs [three.js - function raycast( raycaster, intersects ) lines 14396-14399 :

**start = Math.max( group.start, drawRange.start );**

**end = Math.min( ( group.start + group.count ), ( drawRange.start + drawRange.count ) );**

**for ( j = start, jl = end; j < jl; j += 3 ) { …**

My workaround is to use the first material and skip the multimaterial implementation

**var m= Array.isArray( material) ?material[ 0]:material;**

**… code for single material using variable ‘m’ …**

It’s a functional workaround for my case because all groups overlaps, but not a generic solution!

So the question: any ideas how to solve this?

Thanks in advance
