This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

Apache tutorial, Dynamics part - MultPP attributes

Hi ,
on the Apache tutorial animation disc, he runs through what he did to create smoke and heat distortion.

In his expressions he refers to some constant attributes called spriteTwistMultPP and spriteScaleMultPP.

I cant find these in the general list of perparticle attributes to add...so did he create these...and how do you do that properly?

It's my first experience with expressions so would appreciate any help.

Thanks

I haven't got Maya open so am not sure but they sound like custom made attributes that would be connected to the sprite scale and sprite twist attributes.

Thanks...I realised I was being stupid and added the attributes and mapped them with a ramp.
