Thank you, that was what i needed to change to fix it. But now i get a new error saying,
"// Warning: arrayToPointColor1: inRgbaPP array length does not match the point count."
Whenver i plug the "VDBAttributeFromVDB" node into the "arrayToPointColor" node. I have checked on point position in the "pointAttributeToArray" and i have specified i want the vel grid in the VDBAttribute node.
Thanks in advance.
EDIT: I managed to fix the issue. I HAD forgotten to check on point position, sorry for the trouble.
