Effects which add (build) or subtract

[Andrew Palmer]

Hi all,

Am I correct in thinking that the only way to create an effect which adds/subtracts to/from (i.e. modulates) existing attribute values is to use Shapes?

I can't find a way to do this using Keyframe Shapes or 'simple' Cues which appear to be limited to LTP or HTP.

I tend to busk using faders for intensity and pallets/playbacks for effects. However, Keyframe Shapes on the intensity attribute appear to always be LTP rather than add/subtract, which results in fixtures being on even when my intensity fader is on zero.

It is a shame if this is a limitation as Keyframe Shapes make it very easy to create great effects on 2D arrays of fixtures, which are not possible with normal Shapes. I'm sure normal Shapes will be sufficient for my needs, but it would be helpful to know if I should stop searching for a way to do it another way.

Cheers,

Andy

You are correct in that shapes are relative and key frame shapes are absolute. If you set the playback option to 'HTP Fader' (default) or 'Fader' the associated fader will control the dimmer level of key frame shapes.

Thanks for that. I now owe you two drinks!

In the wiki at https://www.avolites.de/wiki/shapes:start you'll find some more information about shapes, the patterns used, as well as some more patterns and shapes, e.g. shapes which ONLY add resp. subtract.

Thanks for that suggestion.

I had looked at the possibility of modifying the shapes.xml file but didn't want to run into problems when Avolites updated the file themselves. However, just looking at the file is a good way of understanding what all the shapes do.
