From abde0d4efb897581df2a6a7be591de2224611b90 Mon Sep 17 00:00:00 2001 From: Robert Adams Date: Tue, 26 Mar 2013 15:02:10 -0700 Subject: BulletSim: prevent asset fetching loop when the fetched asset fails to mesh. Check for the case where the fetched mesh asset fails meshing (degenerate triangles or no physical mesh). In this case, the asset is marked 'failed' and BulletSim doesn't keep trying to fetch over-and-over trying to get a good asset. --- .../Physics/BulletSPlugin/BSShapeCollection.cs | 116 ++++++++++++--------- 1 file changed, 64 insertions(+), 52 deletions(-) diff --git a/OpenSim/Region/Physics/BulletSPlugin/BSShapeCollection.cs b/OpenSim/Region/Physics/BulletSPlugin/BSShapeCollection.cs index a6e20a8..b6ac23d 100755 --- a/OpenSim/Region/Physics/BulletSPlugin/BSShapeCollection.cs +++ b/OpenSim/Region/Physics/BulletSPlugin/BSShapeCollection.cs @@ -929,67 +929,79 @@ public sealed class BSShapeCollection : IDisposable if (newShape.HasPhysicalShape) return newShape; - // If this mesh has an underlying asset and we have not failed getting it before, fetch the asset - if (prim.BaseShape.SculptEntry - && prim.PrimAssetState != BSPhysObject.PrimAssetCondition.Failed - && prim.PrimAssetState != BSPhysObject.PrimAssetCondition.Waiting - && prim.BaseShape.SculptTexture != OMV.UUID.Zero - ) + // VerifyMeshCreated is called after trying to create the mesh.
