cribbidaj Posted August 1, 2012 Share Posted August 1, 2012 I am rendering a scene with 2 models and a targa imported as a layer in a choreography. The tga image appears with a "white" outline when rendered. I have edited the image in photoshop, making sure all of the edges of the image are black, and included an alpha channel and played with the layer's options settings - "flat shaded", "occlusion", etc. - but the white outline continues to render. The image I've attached is a render using the"white render" settings I just found in another post in these forums (very beautiful, soft rendering style! - thanks, Jason!), but this "white outline/edge" I'm describing appears on the targa no matter what rendering options I choose. How do I get the image layer to render without this outline? Thanks. horse0.tga Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted August 1, 2012 Hash Fellow Share Posted August 1, 2012 That does look like an alpha channel problem. Can you post the image? Quote Link to comment Share on other sites More sharing options...

Hash Fellow robcat2075 Posted August 2, 2012 Hash Fellow Share Posted August 2, 2012 I think it's a case of the alpha channel not being tight enough. I took it into PS and saw there were still areas where the alpha channel wasn't quite making it to the black edge of the drawing. For a quick fix I... Under "Selection" I did "Load Selection" of the the alpha channel with "invert" checked", did "Grow" several times, Filled the selected area of the Alpha channel with black resaved Black_Dog_revisedAlpha.zip Some parts like the tassels still have a white edge, they would need to be tightened by hand some more. Also drawing a black border all around the perimeter of the figure would ensure the alpha channel is catching no white pixels. Quote Link to comment Share on other sites More sharing options...
cribbidaj Posted August 2, 2012 Author Share Posted August 2, 2012 Thank you! I guess I have some preference messed up in photoshop where a pasted object is placed several pixels askew from the copy. Really appreciate the help & the edited file! I think it's a case of the alpha channel not being tight enough.
