Hi

Eventually found the solution to making particles only appear on the white areas directly, courtesy of post by Doug Y, thanks Doug!

– Set the ‘Emitter Size Z’ parameter to 0.

Thanks Creative Cow!

Thank you Michael for you reply

I will file a ticket to Maxon.

Your advice about using the same texture as layer emitter unfortunately only partially worked, the particle stars are appearing in the ‘relative’ area of the white morse code now, but not staring birth on the white area, see jpeg, so I need to find that reason.

Thank you again

See jpeg. If you look closely the stars only appear over the morse code. I have to work on the project again, and of course as Trapcode has been…

Thanks Graham, I have thought about this, the size of intended projected frog will quite large, probably 6 foot swimming across a floor, and the viewer would very close to it, yes I have my pond with ripples and reflections, but the focus would be on the frog, if there is a slight chance the result is cartoonish I can’t get away with that. I…

Thanks Walter, I have tried this already, and the result is ok, but not good enough for the project. I haven’t found really good footage to work with as well. But will continue looking.

Thanks Ian

Hi, I’m wanting to create a realistic swimming frog in AE, looking from above or birds eye view, but can’t find any green screen type stock-footage anywhere. I need to key out on to a pond environment. I wondered if any one had any suggestions, or in the C4D world which AE has the plug-in for. I don’t want a cartoon style movement, it needs…
