7Losses Posted August 6, 2016 Share Posted August 6, 2016 How exactly does attribute interpolate work? I have the following network but when I change the mountain SOP the points jump all over the place! I've turned on Prim Num attribute and sourceprimuv attribute in the scatter SOP.

acey195 Posted August 6, 2016 Share Posted August 6, 2016 (edited) I think the scatter on the left must be done without going through the mountain SOP. Or maybe the other side, but I think at least one side should skip the mountain SOP Edited August 6, 2016 by acey195 Quote Link to comment Share on other sites More sharing options...
7Losses Posted August 6, 2016 Author Share Posted August 6, 2016 I thought that skipping the mountain SOP with the scatter was correct as well. But when I skip the mountain SOP the points don't move at all! Quote Link to comment Share on other sites More sharing options...
mestela Posted August 6, 2016 Share Posted August 6, 2016 The idea is to make sure the scatter doesn't change over time, so either directly connect it to the torus, or put a timeshift before it and remove the default expression so that it stays locked on frame 1.

7Losses Posted August 6, 2016 Author Share Posted August 6, 2016 I am trying to make the points stick to the surface of the geometry as it is deforming. Here is the file with both methods. interpolate.hipnc Quote Link to comment Share on other sites More sharing options...
Malf Posted August 7, 2016 Share Posted August 7, 2016 I just had a look at your scene. You need to have the attributes you want to interpolate filled out on the node in the 'Point Attributes' parameter. It defaults to * but your nodes have nothing in there, you will at least need to have P for it to move the points. 1 Quote Link to comment Share on other sites More sharing options...
