View Full Version : fluid texture coordinates

Can I access the fluid texture coordinates with the getFluidAttr, and setFluidAttr commands?

The documentation says the valid attributes are, "force", "velocity", "density", "falloff", "fuel", "color", and "temperature". I would like to try some tests manipulating the texture coordinate grid. Any help would be appreciated.

I still have not found the attribute name to use with getFluidAttr, for texture coordinates. Has anyone else managed to do this, or is it even possible?

Hey Derek,

if you right click in the numeric field for that attribute, and choose create expression, won't it tell you the correct syntax to control that attribute?

Thanks for your reply.
Unfortunately I can not find a numeric field that displays what the texture coordinates are for a certain voxel. Please let me know where I could find such a field.

Perhaps someone from Autodesk can answer?

Hi Derek,
yeah i dont know if you can do that with existing mel commands.
however if you cache the fluid then you can use fluidCacheInfo

from the help docs

-attribute(-at) string
Modifier to the "hasData" flag, used to query whether a cache has data (at the current time) for a specific fluid attribute. Valid attribute values are "density", "velocity", "temperature", "fuel", "color", "coordinates" (for texture coordinates), "falloff".

Thanks for taking the time to reply, phildog.

I took a look at the fluidCacheInfo command. It returns a 1, if the cache has any data for a given attribute at a given frame, or a zero, if it does not. Unfortunately it does not return any info about what that data actually is.

I would love to get a definite reply one way or the other about this.
