Hello SESI,

According to Houdini Help, neither mattrib() function nor texture3d() support matrix type arguments. Is there any chance their functionality can be extended?

I think at least of 1 case where we may need that - to output Pref(16) attribute to texture3d, created by Rest SOP - so that to keep metaball spacial transformations and get those to shading context.

Thanks.

Hmm… as a work-around, would you be able to use the prim_attribute() function (which does import matrix attributes)?

The other work-around would be to split the matrix attribute into 4 vector4 attributes and then combine them when evaluating. Which isn't very pretty.

I've submitted an RFE (27923) for this.
