Making progress.
Been able to set up basic cycles using flipbooks and basic crowds using flipbook and planter… results are decent but need to figure out how to have the flipbooks start at different frames to make them look out of sync.
But in terms of video. I was able to figure out how to import webm video which supports alpha channel. There’s a setting in the player that allows you to select the decoder. So if you enable the webm player in plugins, the player gets a additional webm decoder under its options section. But unreal craps out if your webm doesn’t has a sound layer. So its kinds useless unless your webm has audio. There’s another player called wmfPlayer… that one seems to also be able to play webm, with or without sound.
Of course now I have to come up with a streamlined solution for exporting my webm videos if I’m to work with that format. So i revisited the whole chromakey thing. I was able to get somewhere with it but its still not perfect, but i can see that with some tweaks I may be able to get somewhere. I’m thinking the chromakey route might be the better solution, since i don’t have to preprocess any webm files.
Oh, also i figured out how to use PNG sequences as video, but seems like it bogs down the system whene ever you have a few hundred frames, it give prefect transparency but also audio is not keep synchronized.
