Creating attributes in Shop VEX

[Macha]

Is it possible to create point attributes in a shop vex network?

It is possible in SOP with the add and parameter nodes but it doesn't seem to work/exist in shop.

During rendering the shaders are called for each sample, not point, so I think I understand why we can't create or add attributes that way, but is there a workaround?

The reason why I ask is because I am dealing with millions of points. If I could calculate color or scale or other properties in a shop vex then that would save me a lot of memory.

Not really a work around, but maybe to bounce something off with. Create the points before hand(even if it's just a single point) and you can modify the attributes in the shader, to be more than just that one. Like assigning Cd and then modifying that color, or turning it into a vector. The values don't need to be anything too important if you can complete change them, once you have somethign to work with. I think I saw a bug fix a little while ago that let you pull in PTNUM, but I could have been dreaming.

I like all of my look attributes in the shader, I hate it when people earlier in the pipeline have locked that stuff in(disp, color, which shader) so I've had to modify a few things like above that way(mostly breaking stuff).

Scale as a physical attribute to geo can not be changed(displacement, but that's proably your enemy when you talk about that many points), but for a sprite you can just have them at the largest setting and scale the uv of a sprite card, for alpha.
