MASH map helper and projection axis
Steve Davy
I'm a bit confused about the relationship between the Strength Map's Map Projection Axis attr and the Map Helper.
When a Map Helper is created, this provides a plane that visualizes the direction of the Strength Map's projection, and is also very handy for animation purposes.
However, I would expect that this would then disable the Map Projection Axis attribute, or at least cause the Map Projection Axis to have zero effect. However, this doesn't seem to be the case -- the Map Projection Axis attr remains accessible, and changing its type even after creating a Map Helper seems to affect how the Strength is being calculated.
Ian if you're listening can you throw some light on this, or anyone else?

Wait, duh, I think it automatically switches to UV when you create the Map Helper, but the other options remain available. It's obvious now.
Here's another question -- should an animated texture as the Strength Map have stable results?
I've had good results with a baked frame sequence with a network of just a few hundred points. However, am now attempting one with about 10,000 points and an animated ramp as the source of the Strength Map. It's doing what I want but with a whole lot of jitter in the points.
Do I need to bake out frames?

That way the bounding box of the texture is fixed (and not dependent on the MASH network’s bounding box, which could be changing, which could lead to jitter).
Best,

Hi Ian,
First email seemed to die, so here it is again.
The texture, a radial ramp, is affecting a merge node between two networks with mesh distribution. The source mesh has scatter distribution, the destination is set to voxel. Have a look at the attached movie
The ramp is simply animating its black and white points in a sweep projected down the axis of the frame mesh. As you can see it basically works, but I'm getting weird behavior at certain frames (like frame 285) where a number of the merged points are popping to other places in the mesh, then back again. The "bad" frame numbers seem to be consistent.
Baking out a frame sequence didn't fix the problem so it seems it's not texture related. Should this work with a voxel-type mesh distribution?
