Hi,
I'm still working on a realflow importer that I will open source if I ever manage to finish it :) But I have a big problem with the texture coords cluster and I need some help.
The geometry generator works correctly, but in the uv operator, the cluster property doesn't have the correct number of elements in the OutputTarget or the InputPorts. Here's a simple test I did : connected the geometry generator, created a projection with the default
op frozen (it becomes an ExplicitUVW) and connected the uv operator this way:
Output Port : the uv ClusterProperty
Input Port : the parent Primitive
Input Port : the same uv Cluster Property
Input Port : the parent Cluster
In the update function, I traced the elements count of all input port objects :
- Primitive.GetGeometry.GetSamples.GetCount is the correct value
- Cluster.GetElements.GetCount is the old value
- ClusterProperty.GetElements.GetCount
is the old value
output target:
- ClusterProperty.GetElements.GetCount of the OutputTarget is also the old value so I cannot write the updated UVs.
I also checked the Cluster flag IsAlwaysComplete and it is true, so I concluded that the clusters are out of sync with the geometry when I receive them in the operator. I assume it means the clusters are not updating at all if I change the geometry with an operator.
Any idea ? I there a way to force the clusters to sync their sizes ?
Thanks,
Etienne Pellerin
