Hi all, any help with this much appreciated.
Is there a way to take a primitive (or point I guess) attribute on an object and pass it through to mantra without involving the shaders?
This is to create an id pass on a scene I have picked up without opening up the huge array of materials in the scene. I can of course go in and add bind exports and the like to feed to the extra image planes but this would be rather painful.
I see we have the op_id option but the help states this will change on each run of houdini which would seem to render it useless for this purpose?
Many thanks,
Richard.

Hey all. Simple question I am sure if someone has a moment please!
I am after the syntax/expression to truncate X amount of characters from the end of a string in an attribute box.
Many thanks,
Richard.

Super thanks for this, most appreciated. A big help.
fyi when used with a carve before the curve I get a crash if the carve reduces the curve to 0 but a clamp to 0.001 on the value fixes that.

Ah, setting my file reading the cache back in to packed disk primitive seems to do it for reference.

Hi all.
Starting to get up to speed on projects with Houdini now and have a question if anyone can help.
I have a pyro sim cached out to bgeo.sc and am in turn bringing it in with the delay load procedural SHOP so I have a nice light scene and IFDs for the farm.
My question is, is there a way to apply a different material shader to an object that is referencing a DLP shop? My goal is to tweak the pyro shader's material after importing it via the delayed load shader.
Many thanks,
Rich.
