Hello everyone,

I am new at Houdini and I have some issues about the “if” in the texture field.

I want to call different image textures after 200 frames, and for that I wanted to use the if operation.
I've tested many syntaxes for it, but it's not working:

$HIP/assets/bouche_`if($F >200){echo padzero(2,$F%33)}else{echo padzero(2,00)}`.jpg
`if($F >200){return $HIP/assets/bouche_padzero(2,$F%33).jpg}else{return $HIP/assets/bouche_padzero(2,00).jpg}`
if($F > 200, $HIP/assets/bouche_padzero(2,$F%33).jpg, $HIP/assets/bouche_padzero(2,00).jpg) )
if($F > 200, $HIP/assets/bouche_`padzero(2,$F%33)`.jpg, $HIP/assets/bouche_`padzero(2,00)`.jpg) )
if($F > 200)then
	echo $HIP/assets/bouche_`padzero(2,$F%33)`.jpg
else
	echo $HIP/assets/bouche_00.jpg
endif
if ($F > 200):
   $HIP/assets/bouche_`padzero(2,$F%33)`.jpg
    
else:
   $HIP/assets/bouche_`padzero(2,00)`.jpg

Could you help me please ?
Have a great day.

Ps: I used `padzero(2,$F%33)` because I want to loop an image sequence.

you haven't tried the correct syntax though.

In many cases the texture field cannot be animated, so be wary.

The correct syntax for an hscript expression would be `ifs(condition, valuetrue, valuefalse)` for values that are strings. Keyframes or animated attributes may also be more suitable.

Do we know why that is? It's always struck me as mysterious.
