In order to essentially 'draw' in Photoshop over a frame of your animation... then 'camera project' it onto the geo and have it 'stick' .. you'll need to do the following (Frank may know other ways, but this is what I do):
- camera project with 'project3D' node onto geo w/ UVs - unwrap UVs with scanline renderer set to UV - place same geo below unwrapped UV rendered map and input directly into this readGeo node - render this from the shot camera via another scan line renderer ------ This is the only way I know how to draw on a given frame in 2D, then project it onto geo and have it stick exactly as it's drawn Is there a simpler method? At Blue Sky I wrapped this up into a tool called GeoPaint, love to evolve it if possible cause caching sometimes creates issues depending on what's upstream Ari Sent from my iPhone > On Dec 6, 2016, at 8:41 PM, anshul anshul <anshul_e...@yahoo.com> wrote: > > Hi frank, Ari, > When I started this, I start this with UV pass using stmap only but as soon > as I give map/Photoshop work this converts into horizontal lines.
