cascade question - sprite origin

cw

Hi folks,

I've been a-googling, but I have had little luck. Is there a way to set the particle sprite's origin to be not the centre?

If there is no way to do this in cascade itself I could try something in the vertex shader but i'm not overly optimistic.

I ca work around it but I thought maybe one of you folks would know the answer offhand.

Have you tried the initial location node in Cascade? This node will allow you to offset the VFX to any position you want.

Hey thanks, but what I mean is to be able to rotate a sprite around its corner rather than its centre. The workaround is just to have loads more overdraw I guess.

This can be done with an Orbit and a Initial RotRate.
Example:

You set the orbit to have matching Max and Min, on Offset and Rotation, use the Initial RotRate as a negative version of the Orbit's Rotation to keep the sprite from 'moving'. Keep in mind that this is really just an illusion and if you were to look at it from the side it is a much different effect.

The example above has the following stats:

Orbit:
Offset Max and Min: X=0,Y=20,Z=0
Rotation Max and Min: X=1, Y=0, Z=0
Rotation Rate: X=1, Y=0, Z=0

Initial RotRate
Rotation Max and Min: -1

if you're after a pivot offset in cascade the short answer is no, you can't iirc. you can make something in the texture, like you said, using a dynamic parameter and plugging it into the time input of a panner node to move the texture within the sprite but it does create more overdraw. (remember to set the texture to clamp UV rather than tile so you dont get wrapping)

Thanks for all the infos guys. Much appreciated.
