"Generate Mesh Using Points" always has wrong uv sets

[jwu]

Hi,

I just find and fix a problem when "Generate Mesh Using Points", it will not copy the correct uv since the code miss checking the _uvsAttr.Length.

Here is the bug line:

HoudiniEngineForUnity/Plugins/HoudiniEngineUnity/Scripts/Utility/HEU_GenerateGeoCache.cs

Line 1852 in d795c19

if (geoCache._uvsAttrInfo[u].exists && geoCache._uvsAttrInfo[u].owner == HAPI_AttributeOwner.HAPI_ATTROWNER_POINT && positionIndex < geoCache._uvsAttr.Length)

just change the code from:

for (int u = 0; u < HEU_Defines.HAPI_MAX_UVS; ++u)
{
  if (... && positionIndex < geoCache._uvsAttr.Length)

to

for (int u = 0; u < HEU_Defines.HAPI_MAX_UVS; ++u)
{
  if (... && positionIndex < geoCache._uvsAttr[u].Length)

will fix the problem.
