willow wafflebeard Posted March 19, 2015 Share Posted March 19, 2015 hello fellas, lately i been needing a good way to composite smoke on a burning live action actor,i animated a geometry to match the motion of the actoras you might imagine neither the motion nor the proportion match, but most of the time its good enough for sourcing smoke.#ACTUAL PROBLEM#however i find it hard to obscure/mask/matte the smoke since proportion and motion is not a complete match.#CURIOSITY TORMENT#im looking a deep images for the moment( im very new to it) ive tried the DCM seem to be a good candidate for my situation.i got it to work and the recoloring logic, but the file size is huge 700mb for a single exrcontaining rgba, deep, objidbut i dont understand DSM at all,i kinda expecting a depth shadow map looking thingas my lights are also using depth map shadowswhen i import it in nuke it looks empty.(deep channel only has (inf, inf) for (front,back)deeptopoints crashes as soon as i plug it.please share to me some workflows Quote Link to comment Share on other sites More sharing options...
Guest tar Posted March 20, 2015 Share Posted March 20, 2015 You can roto/matte the character in Nuke then use DeepFromImage and set the z to be in the correct position of the deep render. Please see attached Deeper.zip Quote Link to comment Share on other sites More sharing options...
willow wafflebeard Posted March 20, 2015 Author Share Posted March 20, 2015 ok got that, thanks marty!!, by the way do you have an idea how to use DSM?. is it obsolete version of DCM, i read around and found out that its use for self shadowing object..but it show nothing to me in nuke compared to a DCM map.thanks dude!

Guest tar Posted March 23, 2015 Share Posted March 23, 2015 Sorry, haven't used Deep Shadow Maps; I've only read that Deep is/was very similar tech wise to DSM and is why it was first rejected by Siggraph IIRC. Quote Link to comment Share on other sites More sharing options...
edward Posted March 23, 2015 Share Posted March 23, 2015 Deep Camera Maps are kind of like a generalization of Deep Shadow Maps. Quote Link to comment Share on other sites More sharing options...
