Hi There,
I'm doing a custom ICE node with four outputports, two scalar and two
vectors, all per point data.
It's compiling fine, the last output port is working, but I'm getting those
error with the three previous ones:
# ERROR : 2427 - Access to a custom ICE node output port failed. This can
occur when accessing the port from the BeginEvaluate or EndEvaluate
callback.
# ERROR : 2429 - Access to a custom ICE node index set failed. This can
occur when accessing an index set from the BeginEvaluate or EndEvaluate
callback.
# ERROR : 2389 - This custom ICENode is in an invalid state and will stop
evaluating:
There are no Begin or End evaluate at all, and once this appenend,
disconnecting and reconnecting any output port of this node is crashing SI.
I also tried in single threaded mode with and without direct indexing and
got the same result.
Finally If I have only one output port it's working fine
If someone have an experience with this, here is simple example source code:
enum IDs
{
ID_IN_geo = 0,
ID_IN_pos = 1,
ID_IN_norm = 2,
ID_G_100 = 100,
ID_POS = 101,
ID_OUT_A = 200,
ID_OUT_B = 201,
ID_OUT_C = 202,
ID_OUT_D = 203,
ID_TYPE_CNS = 400,
ID_STRUCT_CNS,
ID_CTXT_CNS,
ID_UNDEF = ULONG_MAX
};
CStatus RegisterMyCustomICENode( PluginRegistrar& in_reg )
