Hash Fellow robcat2075 Posted November 8, 2020 Hash Fellow Share Posted November 8, 2020 Re: our discussion today of buffers in OpenEXR... Here is a tut that shows how to make the detail of an OpenEXR depth buffer visible to the naked eye... A subsequent test of OpenEXR render in v19 and v17 indicates something is wrong in v19. For now, do your OpenEXR Rendering in v17 if you need buffers. Quote Link to comment Share on other sites More sharing options...
Tom Posted November 8, 2020 Share Posted November 8, 2020 Thanks for the tute! I was having trouble creating exr files in either v15 or v19 so it's good to know I'm not crazy ... Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted November 9, 2020 Author Hash Fellow Share Posted November 9, 2020 Answer to another question... what is a shadow buffer for? A shadow buffer will contain the image of just the shadows in the scene. This can be composited between a render of a CG object and a background photo to make it appear that the CG object is casting a shadow in a real environment. When not rendering to OpenEXR, buffers get saved in their own separate files in what ever format was chosen. Quote Link to comment Share on other sites More sharing options...

Hash Fellow robcat2075 Posted November 10, 2020 Author Hash Fellow Share Posted November 10, 2020 This was composited in After Effects which is better suited for this than Photoshop. 1 1 Quote Link to comment Share on other sites More sharing options...

Hash Fellow robcat2075 Posted November 15, 2020 Author Hash Fellow Share Posted November 15, 2020 I was able to re-create in an A:M Composite Project a simplified version of the composite we made in After Effects. It could probably be duplicated exactly if i investigated A:M compositing modes more. Quote Link to comment Share on other sites More sharing options...

Hash Fellow robcat2075 Posted November 16, 2020 Author Hash Fellow Share Posted November 16, 2020 I found the pic I spoke of during LAT but couldn't find. In addition to this image I took to use as the background... ... I shot this one also, with a real object standing-in for where I intended to place the model. With this I could judge the proper length and angle of the shadow, how much ambient light was on the dark side, and what "vertical" looked like. It would have been better to put the camera on a tripod and shoot them both from exactly the same perspective. Quote Link to comment Share on other sites More sharing options...
