Hi everyone,

I am wondering about uses for the surface VEX output variable. I'd like to see if I can use it to do a custom motion blur in compositing. Anyone have any info on how to do this?

Also I will be trying to match up zdepth from houdini with zdepth from lightwave. Has anyone ran into any problems with this?

Any insights would be greatly apprciated.

You could always render a deep raster image of your velocity and use that in
a custom vex COP.

Hi,

I don't seem to see anything about a velocity attribute in the deep raster options. Do you have to define the variable elsewhere in order to render it through deep raster? I would also assume that it would be a “vector” type, correct?


Thanks again!!

The menu only lists some common variables. I think one is supposed to be able to just type in a name. However, the options don't get enabled if you do that. So pick something like Of first and then just change it to your attribute name. This assumes that your shader exports the attribute as a vector parameter of course.
