Well if you set the horz and vert size to the same number your output will be square.

I was asking myself if another parameter on Shapes actor that let get alpha instead of "fill color" when "line size" is used could be a good feature...

You can already do this programmatically Line Size = Alpha Fill.izz

Thanks a lot, your patch makes the stuff very clearly !

@michel Thnx for that answer
Think I was not clear. 
WHat I mean is; my projector is full HD, so 1920*1080
I'd like to make a shape that stays a circle & doesn't go oval. I understood that I then set the horz size & vert size in the shapes actor to the same number (Mark uses 1280) 
The result I then get is that my shape is in a 1:1 aspect, but it's not to been seen in the sides of the projection (only the 'middle')See my patch to see what I mean.
I have the same in the Guru#4 patch....

If you set the horz and vert size of the shapes actor to 1280, you get a video output of 1280 x 1280 pixel. That's it. Your projector will then convert this to 1080 x 1080 pixel. No chance to reach anything beyond.

This 'two sine-wave generators with 25% phase shift' thing will ONLY give you a circular motion on a square stage. If you want a circular motion full screen, you have to take into account that the -50 to 50 for the 'horz pos' is worth (in your case) 1920 pixel, but for the 'vert pos' only 1080 pixel.

As I don't like the generator thing anyway, attached my old school approach.

Here's my attempt - it's not exactly what I wanted to do - I wanted to try and use the layers in the projector actor so each movement would reveal the colour under it but I couldn't work it out.  As it is, each new shape starts from black.  Ideas on how to do this would be ace.

@timbrunsden

Just change the blend mode of the projectors to 'transparent' and it should work like you want.

I am not sure if I understand what you are looking for but in this patch my answer to what I understood.

@Reinhard @jfg Thnx for clarifing that.

Had a look your patches & thank you :)

HI - I managed to solve the layering colours problem by not using the layers on the projector but just switching on/off the different projectors once the shape movement was complete.  A bit of a long way round but it works as I'd envisaged.  Guru2-shapes-TBrunsden.izz
